# So ... before I send these drives back to Seagate and complain,
# does anyone have experience with these 80-68 pin converters to
# tell me whether it could be causing the problem or not?  We

Do you know if the 80-pin to 68-pin adapters were meant for LVD devices?
The drive will only communicate up to 160MBps only if the entire chain
is using LVD rather than SE (Ultra Wide SCSI is the highest SE will go).
My guess is that the converter is causing the drive to kick down out of
LVD mode and down to SE mode, thus capping it at 40MBps.

You will probably need a converter that is meant for LVD devices rather
in order to get the drive to kick into LVD mode.
