Description peter.evans 1999-06-12 16:04:24 UTC
686 based system. 128Mb ram. ATAPI zip drive gives I/O error
every 128th sector, esp. during write. Happens with
ATAPI_FLOPPY support as module and compiled into kernel

*** Bug 3043 has been marked as a duplicate of this bug. ***

ATAPI internal zip drives do not mount correctly.  Mine is
recognized as hdd.  I set up the fstab for:

/dev/hdd4	/mnt/zip	vfat	noauto,rw	0 0

When I mount it, it mounts fine.  When I read or copy from a
zip disk, no problems.  BUT, when I write to a zip disk it
corrupts the file and it is unusable.  This did not occur in
version 5.2.  Please help - I have made the jump to Linux
because of RedHat (since version 5.0) and now I find I have
to go back to my old Windows machine to write to my zip
disks.  HELP!

I was able to replicate this problem in our test lab using an internal
ATAPI zip drive. Whenever a write operation is done using kernel
2.2.5-15, a hdd I/O error message is printed several times to the
screen. Although the write operation seems to complete well enough, it
is probably not reliable.

The problem is solved by upgrading to kernel 2.2.11 (it is a known

This is fixed in the 2.2.11 kernel in Raw Hide.

Workaround provided by madill@inreach.com:

Just a short note to let you know I have learned a different way to
solve the Zip drive problem - one which you might want to share with
others having this trouble.

I used  -   insmod ide-scsi  -  to install the ATAPI / SCSI emulation
module to the kernel.  It now sets up the Zip as sda4 - a scsi device.

It reads fine - writes fine - works great and fast.
