SE/30 internal HDD termination
Posted by: tommijazz91 on 2020-05-29 21:09:37
Hello everyone!

I have a SE/30 that boots from the internal HDD only if a ZIP drive is connected. I initially thought it may have something to do with bad traces on the motherboard (and still haven't checked since it is not my area of expertise), but then I remembered: the HDD is a Seagate 8GB drive taken from an external Lacie enclosure.

Is it possible that I have to terminate it with the switches present on the HDD?

I found the manual for the drive but I am unsure on how to proceed.

Maybe it has nothing to do with this, but the jumper plug on J2 is set to "term power from drive".

Should I set it to "terminator enable", another setting or leave it as it is?

Mine is the "N" model.

Thanks.

You would have to put a jumper on Terminator Enable as well as TP2.

And here I thought a simple change of position would do it  🙂 . Do I have to source another jumper then? Where can I find it?

Honestly the short jumpers are a bit tougher to find than the standard hd jumpers, I have just scavenged mine from other dead drives I've had here.

I managed to find some on eBay and...it worked! Thanks a lot @JRL!
