Ken,<div><br></div><div>Since the drive doesn't spin up, there is one more thing you should try before resulting to any desperate mea$ures. Your drive may be experiencing stiction-where the heads stick to the platters so that the drive cannot start to spin up. The cure for this is a little bit of violence to the drive, i.e. give the drive a good slap or if removed from system a small drop from say an inch or two above your desk top. This can sometimes jar the heads loose and allow the drive to spin up.</div>
<div>One other thought occurs to me, if the drive is set to wait for a spinup signal from your controller (usually via jumper plug), disable that function. Perhaps either that portion of the circuit on the controller or the disk board got fried and if you turn that option off it would spin up on initial power on.</div>
<div>One more thing, you have other SCSI devices on the same controller that still work? If so, it's probably not your controller but if nothing attached to it works, suspect the controller and try a different one before spending a ton of $ on drive recovery.</div>
<div>And another thing--it might be your terminators. On a drive that old (narrow SCSI, 50pin cable, correct?), the drive terminators are usually either two or three SIPP socketed epoxy(?) coated thingys (technical term or art) plugged in near the power/data connectors. You could safely swap those between drives with no fear [provided you take proper anti-static precautions].</div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Thanks for the replies, folks. An update: The HDD *does not*<br>
spin up. My (lack of) experience tinkering with the hardware<br>
(e.g. changing the control board) leads me to see professional<br>
help ("someone who does this all the time" :). Interesting that<br>
I've seen no references to OnTrack, even though they now have an<br>
Atlanta location. Have they become the M$ of the biz nowadays?<br>
Way back in the early '90s when I used them, they were one of<br>
only about 2-3 in the country & were a referral from an HDD<br>
manufacturer (I think it was H-P then). That HDD had "bricked"<br>
but it did spin up. IIRC we got a full 100% recovery and it<br>
was a Unix system as well.<br>
<br>
I've also heard of <a href="http://drivesavers.com" target="_blank">drivesavers.com</a> - any info about them?<br>
I can ship the drive but if there's an Atlanta-area company that's<br>
as good, I can bring it personally and much more safely.<br>
