I recently installed a CFN R-9000 Series 9-track tape drive in a newer
Model 125 with DMA-coupled 114MB drives that is also fully loaded (AIX V2.2.0,
TCP/IP, SNA Services, Distributed Services, Rabbit 3270, etc...).

After working my way past VRM device driver conflicts with the AT Simulator,
I finally, I thought, got the thing to work...  Basically, I'm trying to
read a tape written on an IBM 4381 in EBCDIC using "dd" as following:

dd if=/dev/rtm0 of=tt.s bs=8192

Well 38 out of 40 times it read the data off the tape incorrectly WITHOUT
reporting ANY ERRORS! I was able to read the same tape 100% succesfully on
my VAX 11/750.

CFN said it's an "operator" error and we're saying the drive doesn't work
period.  All drive should be able to tell if it read bad data and throw
up a signal.

Has anyone experience similiar problems with CFN?

I'll appreciate any info or comments...
