I have one of the above Panasonic drives that I am attempting to
use under the AMD64 version of 5.2.1 -RELEASE. The drive works fine
for mouting CD's or DVD's with an ISO 9660 filesystem on them. If
I insert media with a UDF filesystem, however, (either a DVD-RAM
cartridge or a video DVD) then I cannot access the device as I
get and error along the lines of /dev/cd1 not being a valid device.
This is both using mount_udf and also if I just try and get rawdata
from it using "dd".

It was suggested to me elsewhere that this is due to the SCSI system not
recognising the drive properly and that I should ask on this list. How
would I set about trying to track down the problem ?

Thanks,
