I am in the process of building my BlueSCSI for my Power Macintosh 7600. I thought while I was waiting, I would try an old Quantum Prodrive LPS unit (240 MB) out of a Apple Mac LC III. Electrically it is good. However when I boot my CD version of Mac OS 7.6.1 the Drive Setup shows volume is >not supported>. At first I thought maybe the drive did not have Apple firmware, so I made an FWB Hard Drive toolkit bootable CD. That gave an error message too. So while the noise from the hard drive sounds normal and is spinning, I thing the heads are permanently parked or stuck after years of sitting idle.

If you think it is dead/stuck, no point in NOT trying to fix it.. There is the baking method and the freezing method, both are debatable in results.

I have a bad Quantum drive that I tried the freezing trick on a year ago, but it didn't work. And while I have used "baking" of video cards (in late 2009 iMacs) with tremendous success (I have multiple YouTube videos about it, actually), I have never attempted it on any hard drive.

The freezing did not work. I think the R/W heads are "permanently" parked. :)
