Hello All,
I am having problems with my Iomega Zip 100 drive connected to my
ProAudioStudio
SCSI host adapter (device nca0). I get the following message on my
console
nca0/5/0 data length underflow
whenever I attempt to write data to the zip drive. Reading seems OK
resulting
in the message
nca: pseudo-dma timeout
I suspect that the second message is more benign that the first. Data
that I
have written to the drive seem to get truncated or corrupted. This
doesn't
always occur. I have successfully written some large files to the zip
drive,
have read them back, and have found them totally uncorrupted. Others
have been
corrupted. This occurs both with DOS fs and ufs on the ZIP media. Does
anyone
have any ideas what could be wrong and if there is anything I can do
about it?
Incidently, the drive seems to work fine under Windows95 with the same
host
adapter, hence I think it's a FreeBSD driver problem with nca0 rather
than
a hardware problem.
Thank You,
JM
