Commodore-64 Disk Drive Question.

[Aswald]

For the technically skilled...

I have several Commodore-64 disk drives. None of them work. I keep getting a FILE NOT FOUND error message. I tried some of the tips at a website, which did not involve taking it apart, but, no luck.

Any ideas, and how I can go about fixing them?

Thanks! :D

Forgive me for asking the simple questions first :) --

Can you get the drive working on someone else's C-64? Are you sure the disks are fine? Made sure you have everything connected up? Which kind of drive is it?

[Aswald]

It's not the Commodore 64 itself (I've tried them on another), and it cannot be ALL of those disks. The only thing I am sure of is that it's the drives.

One of the drives is that small, fast, white one. The others are the single drive, standard type, by Commodore itself.

The drives are probably out of alignment... seems to be a common problem with those drives. There are programs you can get that will test the alignment of the drive (although how you'll actually run them without a working drive is a question best left to the philosophers). To do this, you'll need to actually open up the drive and fiddle with an adjustment screw. If you do a search for "1541 alignment", you'll probably get some better information than I could provide.

Have you tried formatting a disk and reading/writing it with the "broken" drives? If a drive is out of alignment, it will fail with disks written by another drive, but will work perfectly fine with disks that it's written itself.

After I started buying C-64 disks at flea markets and such my Commodore disk drive went downhill quickly. It eventually refused to load anything at all. I opened it up and found that the drive head was filthy, literally covered with black dirt. The head looks like a white plastic bubble with little black lines on it.
I cleaned it with a q-tiip and some... Simple Green I think? Cant remember. Probably shouldnt use alcohol. Anyway it worked like a champ after that.
I had to leave it open though so I could test the rest of my flea market finds, I would have to keep periodically cleaning it.

Maybe you are doing the wrong commandz. Or maybe you disk drive isn't working probably. I haven't played my C64 for a while and my floppys still work.

Either the floppies are bad, the drive is dirty, or the drive is out of alignment.

If it's all your disks, it's most likely not the floppies. Here's a good site to put you on the right track.

Get some clean disks... old ones can deposit dirt into the drives and mess them about. Open the drives up and give the read heads a clean with a q-tip and some isopropyl alcohol. Plus as said try formatting a disk with the drive once you've done this, that nearly always puts them back in the correct position.
