Bug 142667 – not able to mount vfat partition on amd64.

• Product: Gentoo Linux
• Status: RESOLVED DUPLICATE

[Description Karl 2006-08-03 08:57:30 UTC]

Hi, I'm attempting to mount a FAT16 USB flash disk under Gentoo64 and am coming up against a recurring error.

# mount -t vfat /dev/sda /mnt/usb
AND
# mount -t msdos /dev/sda /mnt/usb
AND
# mount -t auto /dev/sda /mnt/usb

all produce:

mount: wrong fs type, bad option, bad superblock on /dev/sda,
missing codepage or other error.

# DMesg | tail 
gives:

usb-storage: device scan complete
FAT: bogus number of reserved sectors
VFS: Can't find a valid FAT filesystem on dev sda.

# fsck.msdos /dev/sda 
returns:

Logical sector size is zero.

The USB stick has been formatted and reformatted several times and works fine under MS Windows (the stick belongs to a Sony PSP, which also believes the stick to be working fine).

All codepages are installed into the kernel as is MSDOS and VFAT support.

This issue does not appear to reoccur on Gentoo x86.

Any help would be greatly appreciated.

I'm not able to mount a vfat partition on my amd64. 
I get the error: mount: wrong fs type, bad option, bad superblock on /dev/hdc2,
       or too many mounted file systems
while trying mount -t vfat /dev/hd.. /mnt/..
I created a partition whit Partition Magic, windows, but it doesn't work.
When i try to do mkfs.vfat i get: mkfs.vfat 2.10 (22 Sep 2003)
mkfs.vfat: Attempting to create a too large file system



Reproducible: Always
Steps to Reproduce:

Expected Results:  
Mounting my partition so i can play some song ;)
