Hello Gurus

I have an old Quantum Prodrive LPS 52AT drive that doesn't initialize.
When powering on it spins up ok, then clicks few times like trying to find SA but fails.

What do you think? Is it common to have PCB problems with this particular model or more likely a bad head?
I got myself already a donor disk that is identical to the patient disk.

Thanks.

Though rare, I have seen PCB issue before.

If it is heads, then it is ugly. Quantum are a giant PITA for head compatibility.

90percent internal problem and 'surprises' around the corner. Headswap is most probably going to fail 'as is' , yes. I still have a lot of them, 100 per 100 working and refurbished, just in case.

Hi

Thanks for your messages.

So head stack replacement seems to be out of question.
What about swapping the platter to the donor disk, does it make any difference?
I tried to exchange the PCB already. Patient disk still has the same problem and donor disk gets detected as well with the patient disk PCB.

If the problem is likely with the heads, why would you swap the platter? Just think about it.

Yeah, you're right.

Have you guys managed to fix these drives with just head swap or are the odds really more like 1:100?

Thanks.

No problems at all here. Don't know about the rest of the world
