I have been working with the USB drive on Redhat 7.1 (2.4.2-2) for a
year and I am happy with it until this morning.
I disconnected it and used it on a laptop (W98). In the meantime the
Linux box was rebooted.
When I plugged the USB Iomega into linux again, and tried mounting it
with :
# mount -t -vfat /dev/sdc4 /mnt/zip250
it gave me a "not valid block device" error message.
I then looked at fstab and found that after the reboot without the USB
drive, the entry was gone !?! I replaced the line , but got the same
error message.
Can anyone help , shed light ?
THX

Hi again.
Please bear in mind the ZIP worked well for a year until I unplugged it,
the box got rebooted and I plugged it back in, all in the same Friday
13th morning.
# dmesg has this to say ( which is a grave concern because I didn't
specifically nominate IRQ11 anywhere , so wherefor the IRQ conflict ? )
