You didn't say, but you did disable termination in the tape drive when you tried the cable that has its own terminator, right?
Yes, I disabled the tape drive's on-board termination.
I would ask your brother-in-law to try your tape drive in his system. If it works, get him to try your SCSI adapter. Unless you know for sure that it works, the test you did with the old CD-ROM drive you have only proves there is a problem, which we know.
I'll have to do that next.
I did try the same card and tape drive combo in an older piece of hardware I have, which is also running Fedora Core 2. I had the exact same issues there.
To summarize the symptoms:
The card's BIOS recognizes the drive. Every time the bus gets reset the tape in the drive re-tensions.
Upon boot with the card kudzu asks me if I want to configure the card. I tell it to go ahead and configure it.
When done booting I find that the device is not seen and the aic7xxx driver is NOT loaded.
When I manually load the aix7xxx driver with modprobe the tape re-tensions and dmesg shows the following:
scsi1 : Adaptec AIC7XXX EISA/VLB/PCI SCSI HBA DRIVER, Rev 6.2.36

st0: try direct i/o: yes (alignment 512 B), max page reachable by HBA 1048575
Any attempt to access the st0 tape device results in the following:
[root@crashnburn root]# mt -f /dev/st0 status /dev/st0: Input/output error [root@crashnburn root]# gtar tzf /dev/st0 tar (child): /dev/st0: Cannot open: Input/output error tar (child): Error is not recoverable: exiting now
gzip: stdin: unexpected end of file gtar: Child returned status 2 gtar: Error exit delayed from previous errors
Do IDE tape drives work in Fedora? Will my backups be compatible with a different drive? This drive doesn't have hardware compression.
