howto mount logical fat32 partition? (Invalid argument error...)

[Tamas ZADORI]

Hi!

After browsing and googleing a lot I have no other idea how to mount my
logical partition. I'm using RELEASE-5.2.1 with a freshly compiled
kernel (yes, with msdosfs included).

The output of fdisk is here:

#fdisk ad0
******* Working on device /dev/ad0 *******
parameters extracted from in-core disklabel are:
cylinders=116301 heads=16 sectors/track=63 (1008 blks/cyl)

Figures below won't work with BIOS for partitions not in cyl 1
parameters to be used for BIOS calculations are:
cylinders=116301 heads=16 sectors/track=63 (1008 blks/cyl)

Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 7 (0x07),(OS/2 HPFS, NTFS, QNX-2 (16 bit) or Advanced UNIX)
    start 63, size 16386237 (8001 Meg), flag 80 (active)
	beg: cyl 0/ head 1/ sector 1;
	end: cyl 1019/ head 254/ sector 63
The data for partition 2 is:
sysid 15 (0x0f),(Extended DOS (LBA))
    start 16386300, size 100840005 (49238 Meg), flag 0
	beg: cyl 1020/ head 0/ sector 1;
	end: cyl 1023/ head 254/ sector 63

# file -s /dev/ad0s5
/dev/ad0s5: x86 boot sector, extended partition table

After I try to mount it brings up the following error:

root at cheetah:~# mount -t msdos /dev/ad0s5 /mnt
msdosfs: /dev/ad0s5: Invalid argument
root at cheetah:~# mount -t msdosfs /dev/ad0s5 /mnt
msdosfs: /dev/ad0s5: Invalid argument
root at cheetah:~# mount_msdosfs /dev/ad0s5 /mnt
mount_msdosfs: /dev/ad0s5: Invalid argument

Is there a workaround for this? As I mentioned I found nothing on the
web that could help me.

Thanks,
Thomas
