IIsi Hard Drive, can I fix it?

I have a IIsi that doesn't boot. I put the hard drive in an external closure and connected it to my color classic, and the color classic displays the floppy ? at boot up and won't even boot off its own drive, or bombs if I try to turn on the drive after the CC boots off its own HD.

I'd like to get the data off of it if I can, or is it a lost cause? I doesn't sounds bad, but it just locks up the color classic which is odd.

Techknight made a video about a year ago on how to recover data from old Quantum drives that have worn read/write heads. I found it when I was looking for a way of recovering some data from a 80 MB Quantum drive that would spin down upon startup.

Here's the link:


Hope this helps.

When you put the IIsi hard drive in the enclosure, did you change it's SCSI ID? If not then both drives likely have the same SCSI ID which may be why the CC won't boot.

How do I do this? There's a number switch on the box but it isnt connected to anything. There is a Conner hard drive in the enclosure already that works fine with the CC

Most likely the drive is a Quantum 40 or 80mb.

On the drives circuit board the SCSI ID jumpers are marked A0, A1, A2.

Mac internal drives are usually ID 0 which is no jumpers at all on those 3. If you add a jumper to any of those 3 it’ll change the SCSI ID to something else that'll work with the CC

Well now I can see the drive with norton volume recover, but the utility cannot find any partitions on the drive...

EDIT: I gave it a small hit on the side on my table the drive started to boot! Going to try to mount it now. On the CC to pull of files.

Sounds like you better before it starts to not work at all. Seems to be the case with all of my 2.5" SCSI drives. They work for about 30 minutes then - kaput.

First, kaputt is written with two t ::) .

Second, used or even new 68-pin disks are available. If you have the space for the adapter (wich is passive, btw) you could replace very old disks before they fail.

There is an adapter for 2.5" 50-pin SCSI drives?

Acard had something for a while but as I recall, it was pretty expensive - to the point that the Aztec Monster looks affordable.
