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:

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.

I'm still very much a newbie where Linux is concerned but CUMANA/ADFS brought back strong memories from my BBC Micro days. Google has some hits on what seems to be the same problem.
