Dear all,
I have a Sun DAT tape drive that I want to plug into my Linux
machine (AHA1542 controller). It's an old old DDS-1 tape drive.
The drive itself seems to work fine, *BUT* it appears to write data in
compressed format. When I try to read it on a Wangdat 3100 I get an
error. Writing tapes under Solaris worked fine (I've transferred many
Gb of data in this way) but now I've moved the drive to Linux I seem to
be out of luck :-(
Now, I seem to remember that Sun DAT drives had a modified controller so
that compression could be controlled by software. Under Solaris this was
based on the minor device number of the tape drive.
Is it possible to control the tape drive in such a fashion under Linux?
Basically, I want to turn compression off!!!
Vendor: ARCHIVE Model: Python 28454-XXX Rev: 4ASB

Kernel 2.0.33. A 2.1.x kernel is not an option (this is a production
machine).
Much much gratitude for reading this far. Thanks!
