ISSUE: vfat module unable to handle fat32 partition

[Pierre Baillet]

1-One-line summary of the problem:

  a fat32 partition cannot be mounted.

2-Full description of the problem:

 I'm currently using a Debian Linux with kernel 2.2.14 and recently
bought a 18Go ide hard disk. I then created many partitions on that disk
and especially a 13Go FAT32 partition. Under 98, I formatted this
partition and wrote some data into it, to ensure everything was going
well. This partition works perfectly well under 98.

But I've been unable to mount that partition under Linux. I've compiled
the kernel with the good modules (as I can mount a FAT32 partition from
another disk) but this big partition always seems to be a problem for
the vfat module.

Here is the partition table:

Disk /dev/hdb: 16 heads, 63 sectors, 34960 cylinders
Units = cylindres of 1008 * 512 bytes

   Device Boot    Start       End    Blocks   Id  System
/dev/hdb1             1        21     10552+  83  Linux
/dev/hdb2            22        42     10584   83  Linux
/dev/hdb3            43        63     10584   83  Linux
/dev/hdb4            64     34960  17588088    5  Extended
/dev/hdb5            64      2095   1024096+  83  Linux
/dev/hdb6          2096      4127   1024096+  83  Linux
/dev/hdb7          4128      6159   1024096+  83  Linux
/dev/hdb8          6160     34960  14515672+   c  Win95 FAT32 (LBA)

And here is the kernel message when i attempt to mount hdb8:

pbb22:~# mount /dev/hdb8 /mount/E -t vfat
mount: wrong fs type, bad option, bad superblock on /dev/hdb8,
       or too many mounted file systems

kernel console log is:
