| |
Hi,
my office mate has a 1GB USB stick with a currupted vfat fs.
(I don't really know when and how it got currupted. I just mounted it, copied a file onto it, unmounted, unplugged. After that corruption showed up when accessing the newly copied file. I'm running 2.6.33.1.)
Mounting still worked but when accessing the new file the kernel log was filled up with
Apr 22 16:30:18 zzz kernel: FAT: Filesystem error (dev sdb1) Apr 22 16:30:18 zzz kernel: fat_get_cluster: invalid cluster chain (i_pos 34568) Apr 22 16:30:18 zzz kernel: File system has been set read-only Apr 22 16:30:18 zzz kernel: FAT: Filesystem error (dev sdb1) Apr 22 16:30:18 zzz kernel: fat_get_cluster: invalid cluster chain (i_pos 34568) Apr 22 16:30:18 zzz kernel: FAT: Filesystem error (dev sdb1) Apr 22 16:30:18 zzz kernel: fat_get_cluster: invalid cluster chain (i_pos 34568) ...

(~10000 lines)
It seems that fat_fs_error() generates corrupted output (on an Athlon 4850e dual core), and the excessive amounts of output are IMHO not useful.
BTW: dosfsck refused to fix it. BTW2: when my office mate plugged it into her MacBook it caused MacOS to crash ;-)
