LOSS OF DATA AND THEIR RECOVERY
Sometimes, for various reasons (changes in voltage, power problems or the like) that a disk loses guidance / partition and It also, unfortunately, to make mistakes .... to cancel a partition or format the disk wrong ....
The fact that we have lost the partition or the FAT (partition is present, but is blank and unformatted), it changes very little
In these cases because the data on the disc are no longer accessible, because in fact it was deleted (accidentally or by an accident) all addressing the same
In fact, the data are still on the disk and not just have to try to retrieve them, catching the addresses or simply catching up with a copy files to another disk
If you happen something like this council strongly, especially if the data are important, to avoid attempts propitiatory or without a logical.
The first thing is groped by the recovery partition and / or file system and eventually lost, failing, to try to recover the data, before we make attempts to restore operating system (a possible reinstall the operating system would overwrite areas contained data, making it impossible for future recovery)
In the absence of any abnormal situations and strange, usually, at least the recovery is for all, indeed, are often recovered files or fragments of files that were deleted long time ago ...
One might say that, unfortunately, as far as I know, the data contained in a RAID 0 is not recoverable, as the software described below, are unable to correctly interpret the information in the array
Clarification: If a file is corrupted, it means that the data within it are inconsistent, and generally the recovery is not possible, it is in this case an issue of integrity of the data and not the loss of his address on the disc
NB: this refers to discs that lost the routes and not physically damaged disks
In the event of damage to the physical disk, no software can recover the data, because the damaged area is physically unreadable, at best will be legible other areas still intact and thus can be a partial recovery
We distinguish between:
- Recovery partitions and / or File System
- Data Recovery
