[Bug 1083080] Re: mounting USB flash memory corrupts FAT

Mon Nov 26 09:08:50 UTC 2012

** Description changed:

  With 2 USB flash memory sticks in 2 computers the stick became corrupted
  upon mounting.

  OS: Xubuntu 12.04.1
  Filesystem: FAT
  (1) The files on the memory stick were added in Windows, after deleting a few other files.

  Message at mount:
  Failed to open directory "6C52-B122".
  Error when getting information for file '/media/6C52-B122/2¥w≤û╬. ╗.': file or directory does not exist

  [NB, the second message could be "Error when getting information for
  file '/media/6C52-B122/2¥w≤û╬. ╗.': file or folder does not exist",
  because the last part was Dutch]

  Then I opened the stick in Windows and the files were lost. In Windows, the directory tree was reverted to the tree that existed before the files were added in (1).
  Opening of any file in the reverted tree was not possible.

  Back into Xubuntu I got the following message:
  Failed to mount "2.0 GB File system".
  Error mounting: mount: /dev/sdd1: can't read superblock.

  Reformat (in Windows) the stick to NTFS solves the problem.
