>Description:
newfs_msdos creates an invalid image. A side affect of this is Windows XP sees the image as being full. This error persists even after mounting and copying files to the image.
>How-To-Repeat:
# newfs_msdos -F 32 /dev/da1
/dev/da1: 2014208 sectors in 62944 FAT32 clusters (16384 bytes/cluster)
BytesPerSec=512 SecPerClust=32 ResSectors=32 FATs=2 Media=0xf0 SecPerTrack=32 Heads=64 HiddenSecs=0 HugeSectors=2015232 FATsecs=492 RootCluster=2 FSInfo=1 Backup=2
# fsck_msdosfs /dev/da1
** /dev/da1
** Phase 1 - Read and Compare FATs
** Phase 2 - Check Cluster Chains
** Phase 3 - Checking Directories
** Phase 4 - Checking for Lost Files
Free space in FSInfo block (-1) not correct (62943)
Fix? [yn] y
1 files, 1007088 free (62943 clusters)
>Fix:
(Run fsck_msdosfs after creation)
