I have found that I can get the tape drive to work if DMA is turned off.
The tape is setup as hdd during the boot process. However, there
is no entry created in /dev for hdd. The only way that I know to
disable DMA is for all IDE drives, using ide=nodma. Since /dev/hdd is
missing, I cannot figure out a way to use hdparm.
Is there a way to turn off the DMA for only the tape drive?
Thanks to those who responded to my requests for help.
