I have been using the following to set up a Seagate STT8000A, where the 
tape is hdb.  DMA has not worked with ide tape drives after kernel 
2.6.9.  See Bugzilla 
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=150335

1. append hdb=ide-scsi to grub.conf boot command

2. turn off DMA for tape drive:
a) use "MAKEDEV hdb" to create /dev/hdb
b) "cp -a /dev/hdb /etc/udev/devices"
c) add "hdparm -d0 /dev/hdb" to /etc/rc.d/rc.local to turn off DMA
