Not a good sign. Bad drive or SCSI->MFM adaptor. The error reporting being turned on is key, the format utility itself ignores most other errors except a bad sector 0.
okey doke.
Those Miniscribe drives are lucky they spin up at all anymore. Most likely its the drive. I have a pile of bad MFM drives from 9100's - the Seagates all suffer from stiction, the Miniscribes media starts failing (or the platter motor can't maintain accurate speed anymore)...
I believe my 9100 was NOS when i got it in 1998? i used it on an almost daily basis from 2000 to 2005 i would say, then it went into storage for a year, when i got it out of storage, the hard disk wouldn't spin up, after moving the rotator arm i got it going again and its been fine up until now (so its done a few months work now) and then i fudged it up by doing the system upgrade heh. All in all, i've defo had my moneys worth, and can't really fault the drive :)
SInce you've already upgraded to the version 5.0 ROMs, get a used SCSI drive off eBay and replace it. Plugs right into the SCSI controller you already have, just remove the SCSI->MFM adaptor mounted on the drive cage. Much simpler design and one fewer point of failure.
So i decided to do just this, looked on ebay, only thing i thought of that i would find a small scsi drive in was an old mac... sure enough i won a mac SE on ebay and went to go get it from south london on the train heh. I thought it might have a 40 or an 80 meg drive, sadly it has the stock components, 1mb ram (256k simms) and a 20meg scsi hard drive... and when i booted it up, it sounds suspiciously like the fluke......
Note that if you plan on using the Editor (with a keyboard/monitor) you'll need to stick below somewhere around a 400MB drive. Theres a rollover bug where the free-space calculation is not accurate with larger disks. I believe the largest drive I have in any of my 9100's from Fluke is 320MB. I usually try and get one of the 1/2" height Quantums (like a LPS series), eBay usually has a selection of cheap pulls from old Macs.
so, on cracking open the mac, what should lay before me, but a Miniscribe 8425S hahaha the scsi version of the mfm that died... still, it works, and i'm willing to give it a go... pulled from a fully working mac remember... but the problem now is that i can't seem to format it from the service disk, which format option should be used to format it? old setup was western digital/miniscribe 8425... options are : - western digital / miniscribe 8425 - western digital / tandon tm362 - adaptec 4000 / miniscribe 8425 - adaptec 5000 / miniscribe 8425 - rodime 6052 with disconnect - rodime 6052 without disconnect - rodime ro3057s after choosing to format under any of these configs, I get a further option of formatting with dma or without dma, which option should be selected? i've tried a few combos and everything so far is giving me errors one way or the other.. i would assume that adaptec 8425 would be about right, but nothing works so far.. unfortunately none of the errors stay on the display long enough for me to read them/write them down, stupid software. anyone have an idea of which is the right combo to try? cos if that doesn't work then maybe something else is up? also, might i be missing something on the scsi ID setting, would this cause these sorts of problems? it came from the mac, so would assume id:0 .. is this what the old mfm controller tells the scsi interface that its plugged into? or is it another id? thanks in advance Andy _______________________________________________ Techtoolslist mailing list Techtoolslist@flippers.com http://seven.pairlist.net/mailman/listinfo/techtoolslist
