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.

Comment 5 Stephen Miller 2008-02-13 17:15:51 UTC
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.

Comment 6 Jon Stanley 2008-02-13 17:34:04 UTC
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.




Comment 7 Jon Stanley 2008-02-13 19:08:02 UTC
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.  :)

Comment 8 Stephen Miller 2008-02-13 19:34:12 UTC
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.

Comment 9 Jon Stanley 2008-02-15 21:34:52 UTC
I'll close this one CANTFIX then....

Comment 10 Chuck Ebbert 2008-02-20 22:03:56 UTC
Zip drives can also be driven by the imm driver.

Comment 11 Stephen Miller 2008-02-21 13:34:17 UTC
Tried using imm, no change. Thanks anyway.
