Red Hat Bugzilla – Bug 37032
I/O error on IDE Tape Drive
Last modified: 2008-05-01 11:38:00 EDT
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.
Could you please do strace and send to me the output. thanks
User Error 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- scsi.o
