The Sinclair QL Forum

The working MDV2 I fitted in my main QL is quite noisy (compared to the whisper quiet MDV1)

This is without any cartridge inserted and just typing dir mdv2_

With the lid off the noise is definitely the motor and I’ve tried adjusting the roller to no avail

Given it’s working (read/write/format) is it worth changing the motor with one from a donor MDV? Or is it best left alone given it’s fully working and the least used?

Any thoughts please?

Many thanks

Hi,

Have you verified that the springs are applying enough pressure?

Springs?

The only springs I was aware of are on the right of each mdv with the switch, but these don’t come into play if there’s no cartridge inserted?

Oh, excuse me, missed the part that you had no cartridge.

Ok, thanks

Hi,

I have spare microdrive units available if required.

I had a noisy microdrive and resolved it using some 'slug slime' - a fine modelers lubricant - just a drop on the top and bottom of the motor, and run it for a while - it should quieten down.

Was the problem a noisy motor? and the lubricant lubricated the motor drive shaft?
