Quantum 80S drive not spinning

[Retrotechie]

My SE/30 project has this drive and I’d like to see if I can get it working. It is getting good 5v and 12v but I don’t feel any spinning. It clicks twice. Any ideas?

Usually its by the drive head getting stuck in perished rubber bumpers (which turns to goo getting the head stuck), you will have to open up the drive (in as clean and dust-free environment as possible - don't run it with the lid off like in some videos you see), see if the heads more freely and if not put tape over the rubber bumper.

See this video which refers to a later 3.5" Quantium SCSI HD, but the idea is the same:

Yes, I agree, probably that or worse, heads stuck in the platters.

Remove the cover and have a look, probably a chance to revive the drive.

It just sounds like stiction, in which case all you need to do is give it a bump while powered on.

I’ve tried bumping it with no success. I thought if the heads were stuck the drive would still spin up but maybe the heads are preventing the patter from moving somehow. I’ll open it and report back.

Google ‘stiction’ - the heads can be stuck to the surface of the platters preventing them from moving, which is different from the actuator being stuck to a sticky rubber bumper
