[MacDV] Re: OSX and SCSI

[Richard Brown]

There is definitely an issue here. I can no longer use my DLT tape 
drive for DVD mastering on OS X 10.3.3.

My LVD SCSI card from Adaptec only occasionally can be seen by System 
Profiler, but usually not. It is quite NEW, and formerly very robust.

I use quality, active termination, and had 100% success with SCSI prior 
to 10.3.3. Now, if it weren't for an amiable replicator who will 
master, fingers crossed, from media originating on the amateur 
Superdrive DVD-R, I would have body parts missing by way of an 
non-understanding corporate client.

I tried reinstalling all drivers, moving the $300+ LVD SCSI card to 
different slots, different cables, different SCSI ID's different 
booting routines... and nothing would bring up this relatively new, 
under 30 hours of use, DLT drive, which passes its own self test every 
time it's booted. It has become a very expensive paperweight. As I need 
to author out of DVD Studio Pro, it is useless moving the thing to a 
machine not doing authoring, as I only have a 10/100 network. All those 
gigs.... Must be direct.

Should I find a solution, I will post here.
