<no disk> in Drive Setup

[raoulduke]

I apologize for starting another SCSI HD problem question.  I bought a 9gb 50pin SCSI for $30 on eBay [IBM 00K3970 9GB SCSI].  The seller warrantied it against being DOA.  It 'spins' with what sounds like a laser, preceded by a pathetic grunt of gears that peter out.  Notwithstanding that, in Drive Setup, the drive is listed - correctly with ID0 - as "&lt;no disk&gt;".

I know I haven't exhausted the utmost effort.  I also didn't bother trying patched tools; I just used the stock Drive Setup on the International OS 9 (I think 9.0.4) install disc.  I tried it in an enclosure with a Kanga and internally in my 7100.

My interpretation of these symptoms is that it's nothing short of a miracle anything showed up in Drive Setup at all, and that the "&lt;no disk&gt;" - being similar to an "&lt;unsupported drive&gt;" error off a Quantum 40S - is effectively indicative of serious cylinder problems or sector failures or something.  Any thoughts?  I have about 3 days to try something else, but I don't see why this would be a Drive Setup failure.

*Oh; he also claims he tested it.  But I do not know what that means.  For all I know he got the same thing [error] I did and assumed it worked because something showed up.  Or maybe I'm wrong and I've jumpered it incorrectly.

**I jumpered termination but I do not know if the drive actually has terminators - though I didn't think improper termination is likely to result in.  I think I also tried (and in combinations) disable parity and some type of wide negotiation.

(Also I don't think there's a Term Power jumper setting, but at least in the 7100 the CD drive should have been supplying termination power)

This worries me. By "sounds like a laser", you mean the charging circuits of the Laser as lasers are silent in operation...

But... the "grunt" and "gears petering down", that is a bad sign. Once a hard drive starts up, it remains running, to it would continue to "sound like a laser," not die out. Seeing "No Disk" on HD Set up is another bad sign - the controller of the scsi drive is working but it does not identify the drive or the drive is dead.

If you got it or can get it, use Silverlining and see if it will format from there. But those two signs you stated does not sound promising.

He gave me a refund. Will try more tests later. Yeah the sounds are really startling.

Non Apple SCSI hard drives may need a third party utility to format and use.

Also Termination power may be an issue.  If drive shows but can't be used that can happen.

Doesn't the Apple CD 300 Plus jumpered for termination power solve the termination power issue on the chain - or to the bus I guess?

I'm also fairly sure I tried a proper termination setup.  I put a properly terminated drive in an external enclosure and kept this one internal with no Termination enabled, but I think jumpered to ID1.  It didn't make a difference.

It's also worth noting that Drive Setup takes a very long time (to the order of several minutes) to come up with those lists.  It normally does not do that.  I understand your point about the "&lt;no disk&gt;" possibly reflecting termination - but those sounds alongside?

--  Silverlining couldn't read the drive and gave an error when I tried to format it. Although the Short Tests on Silverlining did pass.  It seems to be stuck on the long tests (I force quit after about 10 minutes). --
