Is exFAT's reputation for data loss/corruption unwarranted?
- cerved 5y agono, not journaled
- blarg1 5y agoI had an external harddrive with exfat that lost all its partition information. Worked one day, then few days later plugged it in and it was all gone.
- GoblinSlayer 5y agoJust write all your data twice, lol.
- simonh 5y agoIf one of them becomes corrupt in a non-obvious way, how do you know which it is? You need three copies to be sure.
- Zambyte 5y agoOr you could save a hash as well
- alias_neo 5y agoWhat if a bit flips in your hash file and changes that? Now you need to store your hash a bunch of times too! I kid, this is what I do. I've recently been backing up my family photos/videos to various media and I've been hashing each file and storing a hash file alongside the media to compare to in the future.
- wila 5y agoNot really. FAT32 is very simple and normally has a copy of each FAT table stored as well. When something goes wrong with the first FAT table, there's a reasonable chance you can still use the 2nd copy. [1] ExFAT is much more complex and AFAICT it does not have a 2nd copy of all of its data. [2] Anecdotal evidence is that I personally lost data on ExFAT file systems, but also have had many customers with problems when they figured to use ExFAT for my backup products. If I see ExFAT in a support bundle than -by default- my suggestion for fixing issues is to reformat to a different file system. More often than not, that's the end of the open support case.
