I'm currently running RH7.3 2.4.20-28 kernel, and when I try to mount a 
USB Memory Stick, I get the following error:

[root at tazenda sunny]# mount /mnt/usbstick/
mount: /dev/sdc1 is not a valid block device

/etc/fstab on my machine looks like:

[root at tazenda sunny]# cat /etc/fstab
LABEL           /                  ext3    defaults        1 1
none            /dev/pts           devpts  gid=4,mode=620  0 0
none            /proc              proc    defaults        0 0
none            /dev/shm           tmpfs   defaults        0 0
/dev/sdb2        swap              swap    defaults        0 0
/dev/cdrom      /mnt/cdrom         iso9660 noauto,owner,kudzu,ro 0 0
/dev/cdrom1     /mnt/cdrom1        iso9660 noauto,owner,kudzu,ro 0 0
/dev/fd0        /mnt/floppy        auto    noauto,owner,kudzu 0 0
/dev/sdc1       /mnt/usbstick      auto    noauto,user     0 0


I've even tried changing that last line in fstab to:
/dev/sdc1        /mnt/usbstick     iso9660 udf,noauto,user   0 0

But no help.

Here's what gets logged when plugging in the USB Memory stick:

[root at tazenda sunny]# tail /var/adm/messages

Feb 24 16:28:24 tazenda kernel:  I/O error: dev 08:20, sector 0
Feb 24 16:28:24 tazenda kernel:  unable to read partition table


What should I do to mount this USB Memory Stick???

Thanks for all the help.
