HELP!!! HELP!!! HELP!!! HELP!!! HELP!!! HELP!!! HELP!!! HELP!!! HELP!!! I have a CMS PD-600 Hard Disk (a Wren V: 94181-702) and a (new) Mac IIfx. Problem: when I removed the (internal) terminators from the Hard Disk (as I am supposed to) it stops working, i.e. doesn't not spin up when I turn on the power. As such I can't use it with the IIfx since that requires the new (black) terminator. The drive works flawlessly with the normal internal terminators (on a Mac II, say). Can anyone advise me what to do? Please respond by email!!! Thanks a million and more!

The two you want are PROBABLY below and slightly offset left of the power connector for one, and the other far to the left, on the other side of the SCSI cable-- I say probably because that's the way it is on my Wren IV. Call Seagate's technical support BBS, and check out the file sections-- you want the specs on the ST4702N. (number is 408-438-8771) The other thing you want to do is make sure the motor start enable pin is NOT jumpered. On my Wren IV that is the two vertically set pins just to the left of the SCSI ID pins, on the same jumper block. -- Matthew T.

On the half-dozen or so IIfx boxes I've put Wren V 94181-702's in, I left the internal termination SIPs in place, along with the IIfx SCSI "filter" that came in the fx. Was this wrong?

Was this wrong? They all work fine. No-- this is correct for an internal drive. I thought the original poster was having problems with an external drive (where the Official Apple Word According To Some Tech Note is to remove the internals and put the black one on). BTW, where did you get a full-height mounting bracket for the IIfx? I'd love to move my Wren IV inside my II, but I can't seem to find anyone who has the brackets. -- Matthew T.

Oops. I guess I wasn't reading as closely as I should have. > BTW, where did you get a full-height mounting bracket for the IIfx?

We get them from MacTel in Austin, Texas. Their phone number is (800) 950-8411. You can see their ad in any MacWeek. I think they also run it in MacWorld and MacUser. MacTel has also been good about selling us empty enclosures for drives we've removed from old Macs to install 600 meg drives. I have no connection with them other than as a satisfied customer.
