Hi,
I am having trouble getting 4.04a to work properly with my Iomega Ditto
800 Insider. All I/O-related commands seem to make the tape drive
"shoeshine", and cause "overrun" error messages to appear in
/var/log/messages.
The command "mt -f /dev/nqft0 retension" works great, so I know
(believe) ftape is installed correctly.
When I load the ftape modules (max FDC data rate = 1000,
threshold=15) and do a "mt -f /dev/nqft0 status" I get the following
from /var/log/messages (sorry about the length; it's all here, though)

The same tape drive and tape worked okay under an earlier version of
ftape (3 something, compiled into the kernel). Any ideas anyone?
Thanks,
