  • +1. But The LBA number and bad block detection is total independent of the file system. Finding files is completely dependent on the filesystem. | I knew that, so maybe I have asked two questions seperately. Commented Aug 2, 2018 at 18:13
  • Can I use LBA lists instead of complete rescans? Commented Aug 2, 2018 at 18:14

    I don't understand the question. If you have an LBA list, you don't need to "scan" (badblocks etc.)- you already have the list. If you want files for a list of blocks for a non-ext filesystem, you still need tools for that specific filesystem. You can "scan" with fibmap, you can even script the scan to use a list of blocks and only touch each file once, but it's still an impractical way to do. It would help if you'd actually describe your situation (like "the harddisk has a FAT and a NTFS partition"), instead of asking general questions for which there's no definite answer.

    Yes. As I already wrote: You can use smartctl (internally reallocated sectors) and badblocks (currently non-readable sectors) for the first step. But didn't you already get the list from Guymager? I'd also advise not to work directly with the harddisk, but use ddrescue etc. to first make a copy of the harddisk (which will also detect bad sectors while doing this).

    I have no idea, I've never used Guymager. But if it knows the number of bad sectors, it should also know which sectors are bad. Just reporting their number isn't particularly helpful... Commented Aug 2, 2018 at 20:53
