This is a request for pointers to existing topics that may discuss techniques for repairing unreliable 68K-Mac-era 50-pin SCSI HDDs.
It's a new direction for me, but (very) recently I've had several Quantum, IBM, Conner, and other HDDs suddenly become unusable. I'd love to return these to operation if possible and avoid creating so much metal/semiconductor waste by e-cycling them. And as they are becoming increasingly rare, it seems worthy to expend a little effort in fighting the tide.
I am seeking any diagnostics, meaningful oscilloscope probes, common sources of failure etc. that might lead to a productive repair path for any drive which is salvageable - or, any advice on how to recognize one too far gone for a hobbyist repairperson to fix.
I realize there are modern alternatives to rotating SCSI-1 drives. I do enjoy restoring a Mac 68K to its true vintage tech and I presume I am not alone, so, bear with me if I go this one final lap. | | 1 |
