Lost clusters and the like. fsck_msdosfs causes cross-linked files (at least according to Windows Vista chkdsk). I can provide you with a broken image that was created as described in the following section. Note that even a freshly created msdosfs file system is already broken. >How-To-Repeat: kamikaze@mobileKamikaze> dd bs=1m count=1024 < /dev/zero > test.msdosfs 1024+0 records in 1024+0 records out 1073741824 bytes transferred in 39.292063 secs (27327194 bytes/sec) kamikaze@mobileKamikaze> mdconfig -f test.msdosfs md0 kamikaze@mobileKamikaze> newfs_msdos -F32 md0 newfs_msdos: Cannot get number of sectors per track, Operation not supported newfs_msdos: Cannot get number of heads, Operation not supported newfs_msdos: trim 8 sectors to adjust to a multiple of 63 /dev/md0: 2096064 sectors in 65502 FAT32 clusters (16384 bytes/cluster) bps=512 spc=32 res=32 nft=2 mid=0xf0 spt=63 hds=255 hid=0 bsec=2097144 bspf=512 rdcl=2 infs=1 bkbs=2 kamikaze@mobileKamikaze> fsck_msdosfs -y /dev/md0 ** /dev/md0 ** Phase 1 -
