Are you able to mount the drive on a Windows system?

This Disk is partitioned and formatted with Windows. (Primary, 30 GB FAT32)

The Kernel Message on SME shows:

Run fdisk -l. It should show your external drive and type of filesystem it has.
Make sure usb disk is detected by system. Run dmesg |grep usb. It should display the information regarding your disk.
Cheers,
Akhil

Thanks for help, the system has detected the USB Disk on usb 1-1:

But the USB Disk is not in the /media folder.

I found this error in the var/log/messages:

I found some posts by searching google (http://www.google.com/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=8gy&q=kernel%3A+Buffer+I%2FO+error+on+device&btnG=Search) that imply that this may be a kernel bug or a problem with some usb interface chips.

I was unable to find any reference to a specific bug.

Post by: paul_NZ on November 15, 2007, 09:15:11 AM: I had (almost) the same problem as you yesterday and followed these instructions http://distro.ibiblio.org/pub/linux/distributions/smeserver/contribs/dmay/smeserver/7.x/smeserver-usb-disk-howto.htm and everything worked perfectly.

I then use a little utility that allows a linux disk to be mounted under XP and browse as per normal.

Please post the brand name and chipset of the case that didn't work for the benefit of other users who might run into the same problem.

Title: Mounting USB Disk - system sees it but can't list any files
Post by: pcowley on January 12, 2008, 11:00:12 AM: Hi

I pluged my usbstick into my sme 7.3 server to transfer OpenVPN client keys - here is what var /var/log/messages has to say:

Jan 12 22:25:48 spock fstab-sync[12561]: added mount point /media/NO_NAME for /dev/sda1

However when I try and list the files on it (and there are PLENTY!) it says:

[root@spock keys]# ls -al /media/NO_NAME
total 8
drwxr-xr-x 2 root root 4096 Jan 12 22:25 .
drwxr-xr-x 5 root root 4096 Jan 12 22:25 ..
[root@spock keys]# ls -al /media/NO_NAME
total 8

So it seems doubly strange that SME thinks there are 8 files (when there are many more including directories) but displays no files at all.

Anyone have any ideas?

Cheers
Pete
