Floppy drives restoration advice

I guess the fridge magnet is safe

There is a thread on a1k in which it is described how to glue 2 square magnets on the heads of a floppy drive and this drive is used just to erase disks.
If you are interested I may take a look.

Yes if you have that link i will go check there, thanks.

The fridge magnet seems to have worked again on another SONY HD disk which had 80% bad sectors and has just formatted fine right now.

I've used neodymium magnets without any issues at all.

Hello.

I have been cleaning and repairing some more drives.

I have this one which unusually has no molex connector but is wired directly to the +5V on the controller board with no other wire (no ground?). The wire is soldered to the broad but i can't unplug it from the molex plug of the drive when gently pulling it. Is it soldered too?
It's annoying because i need to remove this to open the drive.
What should i do?
I could also remove that wire and solder a regular molex to the +5V but why no ground?

Cut the shrink tube with a sharp knife and see if it is soldered.
There is no ground to the molex as it uses the same ground from the 34 pin connector.

Ok will try that, thanks.
