Sometimes, for various reasons (format disks, changes in voltage, power problems or something like) that a disk loses guidance /partition, and it will lead to mistakes such as cancelling a partition or formatting a disk wrong. In result, it most time result in data loss.
The fact that we have lost the partition or the FAT/NTFS (partition is present, but is blank and unformatted), it changes very little. In these cases the data on the disc are no longer accessible, because actually it was deleted (accidentally or by an accident) all causing the same. In fact, the data deleted are still on the disk and not just have to try to retrieve them, getting the addresses or simply backing up a copy files to another disk, say, EASEUS Disk Copy is just a software enables you to copy the whole partition/disk to another.
If you happen to encounter something like this, especially if the data are important, do not try to retrieving your data without any utility. The first thing is groped by the recovery partition and/or files 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 and strange situations, usually, the recovery is for all, maybe the recovered files or fragments of files were deleted long time ago, so you should make a choice.
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 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
If you try to recover lost data, EASEUS Data Recovery Wizard is a most helpful software.
