Disk drive making strange noises
« on: 06:36, 08 September 21 »
I had changed the belts of my CPC about 6 months ago. Since last night the DD is making mechanical noises, and I'm afraid to put Disks inside it now. Is there something I need to check or do?Thanks.

  • It's not broken, it just hasn't been fixed yet.

"Mechanical noises" is a bit general. Can you record or describe them? Is it a clicking, grinding, scrapping sound?

The safest way is to open it up and see what it's physically doing.

It's a grinding noise for sure. I opened it up, and the noise is coming from inside the drive, I can't see where the noise is coming from exactly. Should I risk it and put a disk drive inside or better to dissamble it first?Thanks.

Is the head possibly pushing against the back of the drive (ie: try to go back further than it should)? That's a common fault that makes a grinding sound.

From what I see, indeed it seems to be going further back. Is this fixable?
Thank you

The magnet inside the motor has dis-connected from the motor shaft. It's fixable, but it's a tricky repair. I have a thread somewhere here where I described the repair.

Thanks. I'll search for it, and hopefully find it.

Hi guys,


I'm just having a hard time with my drive as well after being able to recalibrate it and made it read a handful of not working discs.
I believe this threads will also help me, so lots of thanks here!  :)


(BTW, in my initial thread I asked for which screws were needed to fix the stepper motor stator: https://www.cpcwiki.eu/forum/hardware-related/disc-drive-eme-156-stepper-motor-screws/)
