There is a problem with ide-scsi in 2.6, and rather than fix it someone
came up with a patch to cdrecord to allow that application to work
properly, and perhaps "better" in some way. Since the problem with
ide-scsi seems to still exist for other applications, you will probably
find you have to work around the problem, by using the -pad option of
cdrecord (thought that was standard now for TAO at least) or reading
using the ide-cd driver.
I don't remember what the issue was for using ZIP drives with ide-scsi,
other than that using the alternate driver didn't do something right.
That might be fixed, I just went back to 2.4 on my machine which needs
The problem using ide tapes was that you needed ide-scsi to make 'mt'
work, there's no patch for that AFAIK, and tape operations work without
kernel errors, but the data read back didn't have the same md5 as the
data written out. My one IDE tape drive is on the same box as the ZIP,
both seem to work fine with ide-scsi under 2.4. I only use those devices
for exchange with a few clients, so spending time on the problem wasn't
and isn't justified.
Hope this helps you define your problem more clearly.
