Hard Drive bombings

[zydeco]

Hello,

I have a Mac Classic 4/40, with an external Zip drive, that had system 6 installed on the hard drive. When I booted a Zip disk with a fresh install of System 7, I noticed the hard drive had a generic document icon, and if I tried to delete it or paste another one, it would say "it cannot be found", so I decided to format the hard drive.

I tried Lido and Apple HD SC Setup from the zip drive, and both bombed me with address errors, then I disconnected the zip drive and tried Apple HD SC setup from the System 7 disk tools floppy, with the same results, and a "bad F-line instruction" bomb too, when running the test from Apple HD SC Setup.

Shall I bury the hard drive already, or could it be something else?

First check the usual things: Terminations properly located and functional? Power supply stable (measure at drive terminals)? Connectors (inside and out) clean? Unique SCSI IDs for all devices in the chain?

If all that checks out, I'd try using a hard drive tool that does a thorough analysis of the drive and automatically reassigns bad blocks. HDT and SCSI Director are a couple that come to mind.

If the drive still won't play nice, it's time to retire it.
