A500s with bad FDD
 
I have salvaged a pair of A500's from the junk pile, both boot happily to the insert WB disk screen, but neither will read a disk...

Suggestions on where to start?

EDIT: Perhaps I should clarify: Is there anything other than swapping the floppy drive that I should consider? (I realized this is a rather ridiculously obvious thread otherwise ;) ).

clean disk heads thoroughly but GENTLY, open machines and confirm connections are good and solid etc etc

Another issue that crops up with drives that have been sitting for a long time is that the heads seize and can't move. Taking the lid off the drive and carefully cleaning the rails, if possible applying some new, light lubricant, is a good idea too. Over the years, the original grease mixes with dust and dirt to become a thick, gungy mess that hardens on the slide rails.

What happens when you insert the disk?

I've found that WD40 works very well as a solvent to dissolve and clean up hardened old grease. Just make sure to apply new grease afterwards; WD40 is not really a lubricant.

Both drives just click and spin a little.

Looks like I'm going to have to learn how to service a floppy drive.

Never done this before - are there any guides out there? What kind of grease might I need and where would I get it?

Thanks all for the replies by the way!

What model is it? Some suffer from run-out capacitors.

I'm no expert on repairing disk drives but for lubricating the drive I would use either RP7 or a 3-in-1 type oil.

The 500's are both rev5, can't speak for the floppy drives, do they have a model number somewhere on them?

I pulled one drive out, cleaned and lubricated it, but the result is still the same, will keep trying and see if I can pull something off before Goteks arrive in the post...


By the way - I have a working drive pulled from a 1200, can I drop that into a 500?

The model number is often printed on the rear of the FDD.

A1200 drives work fine, as long as they come from Commodore machines. But the mounting requires some ingenuity since A1200 drives are slimmer than A500 ones.

My A500 Rev 6 has a Chinon FB-354 drive, I see them sometimes on EBAY.
