External Hard drives

[melott]

Anyone having a problem with external hard drives
spinning up??

I have an A3kd with the 25 pin scsi port on the back.
Lately I've had a problem with my external drive
spinning up. I'm sure its not the drive because I've
tried a couple other drives and same problem.
I'm wondering if the voltage that signals the drive
to spin up is marginal . I want to install a larger
drive but its not wanting to spin up and I'm sure
the drive is OK. I had the problem awhile back
and I switched the cable from a 24 in. to an 18 in.
cable and that seemed to work.
I'm guessing the voltage is low but what can I do
about it??
Anyone know anything about this??

That was discussed in an earlier thread.....
There is a set of terminators on the MoBo that
won't let the port work more than a few inches
from the connector.
I had done exactly that, connected a ribbon cable
to a 50 pin external bracket but it only worked
with a short (about 12 inches) ribbon cable.
I have seen things written on SCSI where they
use up to 50 foot cables. They must have a way
to boost the signals on a cable that long.
If I can find a pin-out on the external scsi port
then maybe I can figure out what can be done.
Still looking.........
