[LUG] Problems with USB pen-drive...

[Grant Sewell <dclug@xxxxxxxxxxxxxxxxxx>]

Hi all.

I just ordered a loverly 512MB USB 2.0 drive from Ebuyer - a nice Kingston job.  
Shame I can't get the thing to place nicely!

The instructions clearly state that it'll work with Linux 2.4 and above... well, I'm 
pretty sure that 2.6.10 qualifies as "and above".

Here's what happens... I plug in the device (either USB 1.1 or USB 2.0 - doesn't 
matter which) and the device registers itself apparently nicely:

and address 2

However... I can't use it.  Running "fdisk -l" as root shows the following:
Disk /dev/sda: 512 MB, 512753664 bytes
16 heads, 63 sectors/track, 993 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

  Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         993      500440+   e  W95 FAT16 (LBA)

Disk /dev/sda1: 2082.3 GB, 2082317979648 bytes
16 heads, 63 sectors/track, 4034749 cylinders
Units = cylinders of 1008 * 512 = 516096 bytes

    Device Boot      Start         End      Blocks   Id  System
/dev/sda1p1               1         993      500440+   e  W95 FAT16 (LBA)

I have never seen this last entry on a Linux system before, so I'm stumped.  I try 
"# mount -t vfat /dev/sda1 /mnt/pendrive" (pendrive does exist already) and I'm told 
the following:
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
      missing codepage or other error
      In some cases useful info is found in syslog - try
      dmesg | tail  or so

And interestingly, when I try that, I get a load more messages in /var/log/messages:
Apr 14 23:22:51 localhost kernel:  /dev/scsi/host4/bus0/target0/lun0: [CUMANA/ADFS] 
p1<3>FAT: invalid media value (0xb9)
Apr 14 23:22:51 localhost kernel: VFS: Can't find a valid FAT filesystem on dev sda1.

/dev/sda1p1 doesn't even exist in the /dev directory, so I can't access that.

Any thoughts?

Cheers.

Grant.
