Data recovery from system partition
A new hard drive is normally splitted into several logical partitions to treat one disk as if those were multiple disks for convenience and better performance of the hard drive. Isolated partitions increase data safety as well: if one partition is corrupted, data on other partitions remain intact. Traditionally operating system and program files are separated from user files and stored on an independent partition referred to as system partition – C drive: for Windows, for example. As you buy a new computer with a preinstalled operating system you probably get a hard drive with the only partition which is the system partition with user files, program files and operating system stored together. Yet, system partition is exposed to viruses, sudden blackouts, software malfunctions, hardware failures and simple accidental deletion of files causing loss of essential information.
If you've accidentally deleted a crucial file from the system partition, you should bear one thing in mind: as a partition, where constant record is performed, system partition has extremely high possibility of deleted files being overwritten. Defragmentation, indexing, background optimization or OS journalizing as well as temporary files of working programs result in overwriting lost files. Thus, work should be stopped immediately and the working computer must be unplugged without shutting down. Nevertheless, but even an immediate interruption of all operations does not ensure 100% recovery from the system partition after all.
Operating system malfunctions and software or hardware failures may cause damage of the operating system. As a result, your computer will shut down and won't boot again. A blue screen, repeated system rebooting or no desktop indicate a damaged operating system. If the system partition contained nothing more valuable than operating system the problem could be simply resolved by operating system re-installation. But if important files were stored on the system partition or this was the only disk partition, the files will be gone after operating system installation.
Explorer software is a reliable assistant to retrieve your lost files after their accidental deletion as well as after operating system damage. Having shut down your computer, you can choose the most convenient way of the file recovery – using another PC for recovery or recovering from your computer using Recovery CD. In the first case you should carefully remove the hard drive from your PC and connect it to a second computer in a way described in the article "How to: Connect IDE/SATA drive to a recovery PC"
and then start the recovery operation. UFS Explorer Backup and Emergency Recovery CD with Linux operating system can be booted off your PC. It has an already preinstalled UFS Explorer Standard Recovery software with a set of all necessary functions to recover lost or deleted files. After finding and recovering required files, you can copy them to any external device or another computer via network and then re-install the operating system on your computer if necessary.
