1. Overview.

UFS Explorer Standard Recovery software (including its derivatives entitled UFS Explorer RAID Recovery and Raise Data Recovery) is intended for self service lost and deleted data recovery (after deletion, format, malicious software actions, data damage after hardware or software failure etc.).

Among all, the software grants access to files and folders located on inaccessible by OS or standard software file systems and storages.

Such kind of supported storages include hard drives, flash drives, memory cards of digital devices, files of disk images as well as virtual disks of virtualization software of major vendors.

Software supports files systems of major operating systems, including Microsoft Windows, Apple Mac OS, Linux, Unix, FreeBSD, Netware etc. More details about supported file system types may be found in software technical specifications. 'Raise Data Recovery' software has limited support of the file systems.

The software supports optional external modules (plug-in's) that extend software functions. These modules are supplied with the software and can be activated on demand.

UFS Explorer Standard Recovery and derivatives is distributed as commercial shareware software that can be activated. The rights to use the software are passed to the End User according to terms and conditions of public offer agreement – the End User License Agreement.

    2.5 Software settings.

    Software can be started before prior setup. After program is started you will be able to change software settings for more efficient software use.


    Software settings are available on the main software form as property sheet. Values can be changed by pressing 'Change value' button next to the value.

    Software settings will be stored under user profile folder in special '.ufsxsci.hbin' file (Standard Recovery and Raise Data Recovery) or '.ufsxrci.hbin' (RAID Recovery). The software will not save any data into operating system registry or configuration files (except software uninstall information if applicable).

    2.5.1 Temporary files path.

    Defines folder for 'Quick view' tool of Explorer. The software will write into this folder all the temporary files. More information can be found in 'Explorer' description. The changes will take effect immediately.

    2.5.2 Language.

    Allows to change user interface language. It does not apply changes to User Manual. The changes take effect immediately.

    2.5.3. Hexadecimal viewer.

    Defined default encoding for hexadecimal viewer to display symbolic bytes representation. This section also defines maximum number of bytes to copy via system clipboard.

    2.5.4 Explorer.

    Settings include maximum number of objects available on single 'page' of Explorer and maximum number of search results returned by single search operation. Lower values will save memory and increase speed, higher values will allow to operate more objects. The recommended settings are available in hint section (select field header to see).

    The changes will be applied to any next related operation.

    Additionally it is possible to set up default action for file 'Quick view': the actions include opening in hexadecimal viewer or file copying to temporary files folder (p.2.5.1) and launch using default associated application.

    2.6 Software activation.

    Available as a property 'Registration status' and as main menu button 'License'. It displays registration name and registration code entry dialog.


    You have to enter or paste your registration name (used to order the software) and registration code. The registration code must exactly match to the code supplied by reseller: it must be upper-case, include dashes, but exclude any leading/trailing spaces or unprintable characters.

    After valid data is supplied, the software should switch to 'Registered' mode and remove trial limitations immediately.

    If you have problems with software activation:
    • make sure you are using correct software version and edition (different Raise Data Recovery software as well as UFS Explorer Standard/RAID recovery require different licenses for each distinct software edition);
    • make sure if OS platform is valid for registration (different OS platforms require different software licenses);
    • make sure the registration code is copied as described above.

    If the problem can not be resolved, contact software support at http://www.ufsexplorer.com/contact.php.

    3. Operations.

    After software is started, it displays main window containing main menu (top), navigation tree (left) and contextual properties sheet (right). By default left panel displays tree of currently attached storages and properties sheet panel displays software settings.


    Simple data access does not require spacial knowledge: to access a file, activate required disk partition in navigation tree and software will switch to 'Explorer' form. Using explorer-style navigation you may navigate to a specific folder, find and select required file and save it using 'Copy to…' tool from main menu or using context menu option.

    The file can be also 'opened' just by activating it by keyboard or mouse. This will either copy file to folder defined as 'Temporary files path' (see p. 2.5.1) and opened with default associated program installed on your computer or opened in 'Hexadecimal viewer' window depending on your preferences (see p. 2.5.4).

    3.1 Storages tree navigation.

    The tree contains top-level container 'This computer', containing all the opened storages below. The storages will also include disk images and complex storages (RAID). Right side displays contextual properties sheet containing properties of selected object and tool bar with the applicable tools.

    3.1.1 Storages operations.

    The 'Open' tool in main menu and context menu of 'This computer' element allows to open any of supported disk image or virtual disk. More information about supported formats is available in the software specification.

    The 'RAID Recovery' software edition also allows to open saved RAID configurations as well as Runtime Software Virtual Image files (*.vim-files). This function is not available for Standard Recovery and Raise Data Recovery even if used with plugins.


    The 'Open storage' tool in main menu allows to open physical storage by specifying OS-specific device name. In Microsoft Windows you may open volume by supplying volume mount point (e.g. 'E:').

    To access physical drives you must run the software as local Administrator.

    The 'Close storage' tool allows to close the storage in UFS Explorer.

    The 'Refresh storages' tool resets tree of attached storages (closes all the opened storages and re-detects attached storages tree).

    After refresh the tree will only contain available physical drives, excluding any disk images or RAID. In case OS used software RAID, it will be displayed as set of its components. To open such RAID use 'Open device' tool and open the RAID by specifying device name or mount point (such as 'E:' under Windows or '/dev/lvm/vg0' under Linux).

    The contextual tool bar for disk contains tools for lost partition search and definition as well as to save disk content to an image file.

    3.1.2 Disk partitions.

    A disk may be divided into 'disk partitions'. Purpose of disk partitions is data isolation (from other data or OS), different OS installation on the same physical disk etc.


    The software will show disk partitions under 'disk' element (including those with unknown or unsupported file system). The partition name consists of combination of its parameters: file system type, offset, size (in GB). More details about disk partition can be found on partition properties sheet.

    The file system icon will indicate its state: green means file system can be accessed, yellow may indicate problems, red means there are problems and gray means file system can not be recognized. The partition state explanation can be found on partition properties sheet.

    It does not display any information about file system mount point. For example, drive 'C:' may be displayed simply as NTFS-formatted partition of required size.

    File system can be identified by disk and file system size, as well as by its files/folders content.

    After partition activation software opens 'Explorer' window for the file system.

    The contextual tool bar for disk partition contains tools for file system testing, data recovery and saving contents of disk partition to an image file.

    3.1.3 Making backup or disk image.

    If you suspect disk defects, it's strongly recommended to save a disk image file for further data recovery from disk image file.

    For this there are 'Disk image'/'Partition image' tools for 'Disk' and 'Partition' elements available in element context menu and contextual tool bar.


    This makes bit-to-bit copy of disk (or partition) contents to an image file. There are available option to save partial image file (selected data range).

    Entire disk image file can be opened with 'Open' tool and software can use it for data recovery instead of original disk.

    3.1.4 Defining missing partitions.

    The software allows to define missing partition both manually and by automated scan. In first case you may use 'Define partition' tool from disk contextual tool bar. The software will suggest to enter partition start sector and its size (in sectors). If that specific offset contains any valid file system, the software will be able to automatically adjust disk partition size.

    If the software is unable to find valid file system at the given offset, the software will warn about this.


    The lost partition automated search is available though 'Find partition' tool. It opens lost partitions manager dialog that allows to scan the disk for lost partitions in automated mode, save scan result or restore previously saved scan result.

    If new scan is started, software will ask for disk range to scan and file system types to detect. When scan is started and file system of given type is detected, software adds it to list of found partitions. Icon color will indicate the same partition state information as in the main form.

    To add partitions to UFS Explorer disk partitions tree you have to select partitions with checkboxes and press 'Use selected'.

      
    Important: information about partitions that were not selected will be lost if you have not saved partitions list to a file.

    Back to top

    3.2 Using Explorer.

    After selecting disk partition the software will open Explorer window for the file system. If the software did not recognize file system, it opens Explorer window and starts "Data Recovery" wizard automatically.


    Files and folders in Explorer are represented as sorted lists, containing file/folder name, type, size and modification date. You may re-sort the list by clicking to column header.

    To simplify navigation Explorer contains quick navigation panel with support of navigation by navigation history, navigating to parent folders or by typing full path.

    Left side of Explorer window contains folders tree.

    When folder is activated, software navigates to the folder. When file is activated, the software depending on preferences (see p.2.5.4) will either open it in hexadecimal viewer or will copy into folder for temporary files (see p. 2.5.1) and will open with installed associated application.

    Files and folders can be saved to a specific 'local' folder by selecting them and choosing context menu option 'Save this object to...' or using 'Save selection' tool in the toolbar.

    You may select multiple object in Explorer for copying by holding 'Shift' or 'Ctrl' keys when selecting object in list.

    In case you require more complex rule to copy files, use 'bulk copy' operation.

    3.2.1 Explorer pages.

    In case number of files and folder exceeds maximum number specified in software settings (see p.2.5.3) Explorer will use 'Pages' to show all files. At the bottom of Explorer it will show page number "links" to navigate through list pages.

    To copy all the data from such folder you may either use 'bulk copy' operation or apply copy operation for parent folder.

    3.2.2 Bulk copying.

    The option is activated by 'Define selection' button of Explorer panel. This turns both files list and folders tree to 'checkbox mode' to select files and folders for copying.

    The copying rule is defined as:
    • selected with checkbox file or folder will be copied;
    • if the checkbox from file of folder was removed, it won't be copied;
    • if folder is selected, it will be copied with its content except deselected files and folders.


    After all required files/folders selected, press 'Copy to...' to start copying process. Selection can be canceled using 'Cancel selection' button.

    3.2.3 Searching for files and folders.

    The function is available as 'Quick search': just specify sub-string of file name to search on quick search panel or as 'Advanced search': the tool on toolbar, folder context menu or 'Ctrl+F' keys combination.


    Quick search uses string as a part of file name and uses case sensitivity settings of the current file system.

    For Advanced search you may specify full mask for file name (including 'wildcard' symbols '*' and '?'). You may also define rule for file size and for inclusion of files and folders to search result.

    The file search starts in current view and continues until all sub-folders are traversed or maximum number of objects found (see p.2.5.4).

    Search result can be used to navigate to a folder containing found object or to copy found data.

    3.2.4 Data size.

    Before you start copying files and folders it's recommended to evaluate data size to choose matching target storage. You may use 'Evaluate data size' tool available from folder or objects group context menu. There is also "Test file system" tool that can be used for file system consistency quick evaluation.



    If file system consistency error is detected, it's recommended to continue with file system recovery.

    3.2.5 Folders tree panel.

    The panel contains information about currently opened partition, file system and folder for fast navigation. If folder is chosen in left panel, it will be opened in Explorer; this feature can be used for fast navigation between different folders.

    Folder context menu contains all the tools available in Explorer for folder record. If Explorer is in 'bulk copy' mode, you may select/deselect folders from tree by double-clicking them.

    If the file system was scanned with data recovery scan, scan result will be available as a 'file system instance' under partition item element with its own subfolders tree.
    Back to top

    3.3 Lost files recovery.

    Lost files recovery is the main purpose of the software. Search for lost file systems was described in p.3.1.4. This section describes recovery of lost and deleted files (including recovery of user-deleted files, recovery after format, file system damage etc.).

    Lost files recovery is available as a tool 'Recover lost data' in partition context menu or 'Recover' button in Explorer.

    Raise Data Recovery supports recovery only from limited number of file systems specific to software edition. See software edition specification for details. UFS Explorer Standard/RAID Recovery supports all the file systems supported by Raise Data Recovery software and fully covers their functions.

    3.3.1 Recovery process.

    After starting recovery process the software starts data recovery 'wizard' to collect data recovery settings and preferences. First of all disk data range to scan and file system type should be defined. It's recommended to leave data recovery scan range default.

    It is possible to change type of file system to scan (e.g. in case of file system format with different file system type).


    After general parameters are defined, you have to define scan preferences. These settings could be different for different file systems depending on file system specifics.


    These parameters may include search for deleted files, IntelliRAW scan stage etc. For some file systems the software offers 'force sector-by-sector scan' mode that is recommended to enable after file system format.



    Scanning of a file system may take significant amount of time. After scan is completed, the software will turn back to Explorer and show the scan result as a new 'file system instance' opened by default.

    3.3.2 Saving scan result project.

    To prevent scan result loss due to software or hardware failures, it's strongly recommended to save scan result project. If saved, you will not need scan the storage again that could be significant for large and slow storages. The tool is available on the main menu toolbar and scan result context menu.


    If you need to resume recovery after software restart, you will be able to simply load the scan result. This option is available from partition context menu as 'Load recovery scan result' as well as tool in the main menu toolbar.

    3.3.3 Saving recovered files.

    The scan result is available to browse and copy files just like an original file system. This means required files and folder can be saved using all the same tools available in Explorer.

      
    Important: never save just recovered files to the source storage. The file data (contents)for recovery is still read from the source drive; this means software may overwrite files contents Use separate storage to recover the data.

    4. RAID Recovery.

    UFS Explorer RAID Recovery implements all RAID recovery related functions, they do not require any prior activation and are fully available in trial. Other software editions support RAID recovery only via optional external RAID Access Plugin - RAID Builder module.

    The tool is available in main menu of the first form of UFS Explorer RAID Recovery as 'Build RAID'. In other software editions RAID Builder can be invoked though external module as 'Plugins'->'Build complex (RAID) storage'.

    RAID Builder displays new 'Build RAID' window that contains main menu, list of available components (left), list of RAID components (right) and RAID properties sheet (bottom).

    4.1 Building RAID.

    To build a RAID you have to enumerate all its components in the components list, set up RAID parameters and press 'Build' button to add RAID to UFS Explorer storages. For RAID5 supported reconstruction without single drive; for RAID6 – even without two drives. This still requires component specification as 'Virtual disk placeholder' to build RAID correctly.




      
    Note: Incorrect RAID configuration in UFS Explorer does not modify on-disk RAID configuration, however, makes data recovery with such configuration impossible. To start successful data recovery you have to build RAID correctly first. You may perform any number of RAID reconstruction attempts with UFS Explorer because it does not modify data on the source disks.

    4.1.1 Adding RIAD component.

    All opened disks or disk images are available on the left panel and can be used as RAID components. To add disk or disk partition to RAID as a component simply 'activate' it or use 'Add to RAID' menu tool. If you have added a wrong component, select it in the list and press 'Remove' button in the RAID Builder toolbar.

    To add placeholder for a missing drive (only for degraded RAID 5 or RAID 6) press 'Placeholder' button.

    And finally, to correct order of storage components, you may select item and use 'Move up'/'Move down' buttons to set correct ordinal position for selected component.

    If storage component has incorrect size or you have to adjust start position use 'Edit range' tool.

    The user interface behavior section of properties sheet defines how to filter list of available components (show disks or disk and partitions; show all disks or only not added to RAID etc.).

    4.1.2 RAID parameters.

    You may use any source materials to find correct RAID components (RAID board BIOS information, configuration files, on-disk structures etc.). Anyway, you have to specify correct RAID parameters in order to recover good data.

    Different RAID levels use different set of settings. The RAID builder properties sheet is adopted to selected RAID level and allows to specify only required RAID parameters.

    For RAID 6 there are additional parameters (related to redundancy algorithm and distribution) and they have to be specified only in case RAID is reconstructed with missing (failed) drives.

    4.1.3 Automated RAID reconstruction.

    Some configuration RAID can be parsed by the software and software can build such RAID in semi-automated mode. In case any of good component of such RAID is added (p.4.4.1) the software suggests to build RAID automatically.

    On success, the software loads RAID components in the right order and full set of RAID properties.

    In case of failure (e.g. in case of RAID configuration damage) you may cancel automatic RAID reconstruction and build RAID manually.

    4.1.4 Result.

    In case of successful RAID reconstruction with UFS Explorer RAID Recovery it will be added as a new storage in the storages tree. You may apply all the operations available for other storage types to RAID (including adding RAID as a component of other RAID).

    In Standard Recovery and Raise Data Recovery editions this requires activated RAID Access Plugin – RAID Builder module.

    If the module is not activated, it will ask for activation. In case of unsuccessful or canceled activation the module will not add RAID to UFS Explorer.

    4.1.5 Quick RAID evaluation.

    RAID Builder has quick preview tool for RAID that can be useful for quick RAID parameters evaluation for accuracy and trial RAID Access Plugin - RAID Builder module. The tool is available in main menu toolbar and allows to preview partitions located on the RAID as well as file system structure.

    4.2 Saving RAID.

    Available only in UFS Explorer RAID Recovery. To save RAID configuration, select it in the disks tree of UFS Explorer and use context menu tool 'Save RAID configuration'. You may load this configuration in future via common 'Open' tool.

    4.3 Correcting RAID configuration.

    Available only in UFS Explorer RAID Recovery. To change RAID configuration select in the disks tree of UFS Explorer and use context menu tool 'View/Edit RAID parameters'.

    This will display RAID Builder dialog with pre-configured RAID components and RAID parameters. When this RAID is built it replaces original RAID in the disks tree.

    The tool is useful to change (or guess) RAID parameters after incorrect specification.

    5. Legal aspects of using the software.

    6. Commonly asked questions.

    Q: Does software modify data on the source drives?
    A: Source drives are opened as read-only so software is unable to modify the data.

    Q: What is file system on my storage?
    A: In case file system is supported by UFS Explorer it will be shown like 'NTFS partition (sector 2048, 40 GB)'. Here 'NTFS' - is the file system type.
      
    Important: Raise Data Recovery in Explorer mode will warn if file system type is not supported even if recognized.

    Q: Does it support a X file system?
    A: This information is available in the software specification, Anyway, this can be checked by running software trial.
      
    Important: Raise Data Recovery in Explorer mode will warn if file system type is not supported even if recognized.

    Q: How to identify partition in UFS Explorer?
    A: Find the drive and file system of specific size. Anyway, you may open file system in Explorer and check it by contained files.

    Q: Windows dynamic disk was not recognized by the software. Where is problem?
    A: Most likely there is defined complex dynamic disk (e.g. span, stripe, RAID 5 etc.). UFS Explorer does not assemble RAID automatically. If such RAID is mounted by Windows as a volume, you may open it as a 'storage device' by specifying its mount point (NTFS path or drive letter followed by colon).

    Q: Data is stored on software or hardware RAID not recognized by OS. How to access the data?
    A: UFS Explorer RAID Recovery supports virtual RAID reconstruction and use such RAID as virtual storage to access the data. For UFS Explorer Standard Recovery and Raise Data recovery - use optional external module RAID Access Plugin - RAID Builder.

    Q: The disk image file is split into many fragments. How to access the data?
    A: Entire disk image from fragments can be combined using free RAID Access Plugin – Autospan module or via RAID Builder tool of UFS Explorer RAID Recovery as well as RAID Access Plugin – RAID Builder (span mode).

    Q: There are bad clusters. How to read the data?
    A: If the data is very valuable, it's better to contact data recovery service laboratory for data recovery. If data cost is lower than data recovery service fee, you may use the software to attempt data recovery.
    If there are file system errors, it's recommended to use file system reconstruction tools of UFS Explorer. Anyway, it is strongly recommended to access the data from such drive only via free 'Read-It-Once plugin'.

    Q: External drive was not recognized, what are my steps?
    A: Check data cable connection type and if there is enough external power for drive (e.g. 3.5' drives can not be powered via USB). To make software to detect the drive, make sure OS can recognize the drive as a device.
    In Windows: right click 'Computer' choose 'Manage'. Go to 'Storage' and 'Disk management'. Make sure disk is listed.
    In Linux and Mac OS there is 'Disk utility' in system applications section that can be used for the same purposes.
      
    Important: if you have connected disk from other OS to a computer with Windows OS, it is possible that it may ask for 'disk activation'. Decline this prompt in order to prevent data loss.

    Q: The OS recognizes disk but not UFS Explorer. What to do next?
    A: Make sure software is started using local Administrator user account (this is required to access physical drives).
    If other disks (except required) are detected, this may indicate bad cluster on sector 0 of the drive. In this case disk still can be accessed via 'Read-It-Once Plugin'.
