If enough information is present for the recovery software to repair the file system and accurately locate previous files, you should be able to recover quite a bit. In the case of file system damage, the number of files that can be recovered depends on the extent of the damage and the allocation information available to the recovery software. Some file systems, like NTFS, have a higher likelihood of recovery if they're overwritten with the same file system, while others actually have a smaller chance if they're overwritten with the same system-writing XFS over FAT makes it more likely for the FAT files to be recovered. Similar to deleting a file, formatting a file system destroys information about the previous files and structure of the disk, but the amount of data erased depends on the system format.įor example, formatting with FAT destroys a large amount of data, rewriting that section of the disk with zeroes, significantly reducing the likelihood that you'll be able to recover your data. While you might not be able to use what you get, there's always a chance that you'll get a portion of the file back, which could potentially save you a lot of time in trying to recreate it. If not, you still might be able to recover enough information from the table to get some of your files back, though it depends greatly on the level of corruption.Įven if the files you're trying to recover have been corrupted, there's a chance that you'll be able to get usable portions of them back using data recovery software as long as the software can find the file, it will try to recover it. If you can successfully repair the partition table, getting all of your files back should be easy. In this case, it's just a matter of copying everything to another hard drive.Īnother problem that could get you to this point is a corrupted partition table, which might be possible to repair using the correct software.
If you attach the hard drive to another computer, you might find that only the operating system has been corrupted and that the rest of your data is fine. However, data recovery is still possible, even if you see those trauma-inducing words. You know how disheartening it can be to see the words "corrupt hard drive" error.

What You Need to Know File Corruption SSDs handle deleted data and data recovery differently from a hard drive, and you can read more about SSD data recovery further down the article. However, many people now use solid-state drives (SSDs) instead of hard drives. You'll note that the above relates to hard drives, the older, spinning platter devices found in millions of devices. Other systems, however, like UTF and FAT, destroy more information about the file when it's deleted, making it more difficult for file-recovery algorithms to guess the file's location on the disk.

For example, the Windows NTFS system retains file description information after the file has been deleted, making it relatively easy for file recovery software to find the file.
