Can't mount zip drive 100
Last modified: 2008-02-21 08:34:17 EST
Description of problem:
error message from mount:
mount: /dev/sda4 is not a valid block device
Version-Release number of selected component (if applicable):
util-linux-ng-2.13-3.2.fc8.src.rpm (this is for "mount")
NOTE: 2 kernels on my computer: 126.96.36.199-107.fc8 and 188.8.131.52-115.fc8-i686
Steps to Reproduce:
1. MAKEDEV /dev/sda4
2. mount -t vfat /dev/sda4 mnt/zip100.0
error message shown above
device should be mounted
Additional info: drive is powered, disk inserted, used to work with fc4.
Where are you getting /dev/sda4 from? udev should be automatically creating
devices when a device is plugged in, there should be no need to manually make
any sort of devices. Can you attach the output of 'dmesg' from your computer?

I see no evidence here that a zip drive is actually attached. Via what method
(USB, etc) is the drive attached?
There *is* a /dev/sda, but that's a 40GB hard drive.
It's a parallel device (zip 100.0), and always worked in FC4. Can't remember
whether or not I had to manually use MAKEDEV. If I manually edit fstab, I see
the device under "my computer", but can't mount it. Initially, it says "sda4
doesn't exist), implying that it knows sda4 is what's needed. If I then create
sda4 using MAKEDEV, it then says "sda4 is not a valid block device). Running
"file /dev/sda4", it says it's a block special (8/4). If I run "ls -al
/dev/sda4, I get
brw-r----- 1 root disk 8, 4 2008-02-13 12:10 /dev/sda4.
One of the main differences between FC4 and F8 is the introduction of libata -
so that all ATA disks get abstracted as SCSI disks. So there's some definite
collision if you were using /dev/sda4 before - that will no longer work. I'm
honestly surprised to hear that a parallel zip drive still exists :).
Unfortunately, the howto that Google dug up for me doesn't exist anymore, so I'm
not sure how to make this work. I'll try and ping some developers.
Well searching through my gmail archive of fedora-list, I found something that
looks promising. In one window, have a tail -f going of /var/log/messages. In
another window, type 'modprobe ppa'. There should be messages about finding the
zip drive with some luck. I really wouldn't count on this long term, because
I've not been able to find anyone who has done anything with parport stuff for
about 5 years. :)
Thanks, but no luck. I do notice in dmesg, however, this statement;ppa: Version
2.07 (for Linux 2.4.x). I'll just consider this device as being too old. It
still works on a windows computer, which is sufficient for my needs.
Thanks for your help.
I'll close this one CANTFIX then....
Zip drives can also be driven by the imm driver.
Tried using imm, no change. Thanks anyway.
