Description Ian Salisbury 2001-04-22 04:49:26 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)

ide-tape.o loads fine with insmod, and also compiles into the kernel 
without errors.  It identifies the drive (A Seagate STT8000A) and assigns 
it to /dev/ht0.  Every attempt to access the drive gives the 
error: /dev/ht0: Input/output error.

Reproducible: Always
Steps to Reproduce:
1.Install Tape Drive
2.Use Kernel 2.2.19-7.0.1
3.enter 'mt -f /dev/ht0 status'

Actual Results:  /dev/ht0: Input/output error

Expected Results:  Tape drive should have responded.

A google search shows that this is a common problem, some people compiled 
their own kernel and got it to work.  I've recompiled my kernel a number 
of times with differnet options but still no luck.

Tried two different tape drives (Same model) with the same result.  Original 
drive was in a Windows 95 box previously, and working fine.

Found a third drive to try, when swapping I noticed that the stickers on the 
drives were different.  Seagate tape drives LOOK almost physically identical.  
I was using the wrong media.

With correct media I was able to get mt to work with both ide-tape.o and ide-
