If you have more than one partition on the disk, create a separate backup for each partition as some partitions may be more complete. All those LibreOffice documents are compressed which means they can be decompressed only up to the first missing block.Ĭlonezilla, as suggested, is one option. It is really only text files that you can read. The first sector of a file can be missing and make the whole file useless because software cannot decode most binary data unless the start is intact. The data from the files may be there but not identifiable as a file. When the recovery software collects a million sectors of good data, it could be missing the blocks that identify files. All good reasons for one fast pass to recover what ever is usable. Continuous reads of the same spot can break out more material that spreads to other locations. One of the reasons I use Linux to recover Windows disks is the horrible problem of Windows beating to death an old disk without any reports of errors.Įrrors tend to spread. Good recovery software would skip the error and recover all the tracks that have no read errors. The retries make the wear and errors worse. When you get a read error on a track, the software can report the error or just sit there retrying endlessly. CloneZilla might be a good choice, because it doesn't actually copy each and every bit of free space, which results in a lower image size, a quicker clone, and it's presumably less stressful for the drive. Unfortunately, even that isn't ideal, because you might waste valuable time recovering data you don't care about, but missing the important data which you killed the drive waiting to rescue. When you have a drive you suspect is dying, you could clone it with something like dd(1) - or a GUI version of it, if you prefer - then work with the cloned image, rather than risking further wear to the drive itself this is especially problematic with old HDDs, I imagine. In the past, I was working with a really old drive, and it actually completely died as I was trying to recover data from it. Personally, I'd try testdisk(8) on it, but the more you scan (use) that drive, the more likely you are to further degrade it. If it's a really old drive, it has probably just passed away - I'm sorry for your loss.
