- : Back when I was still hacking C64s, I occasionally encountered a 1541 which
- : seemed dead. You'd put a disk in and attempt to load something, it would
- : spin it, click three times, then the red light would flash and it would give
- : up and say that there was no disk present (it's been a long time, is that
- : "21,DRIVE NOT READY,00,00" or something?) Turning it off and on, and trying
- : different disks, was no cure. What was wrong?
-
- Actually, it was "74,DRIVE NOT READY,00,00", but you're close. ("21" is
- "READ ERROR", a message you really DON'T want to see on a 1541/1571...)

-
- : The fix was this: With no disk in the drive, give it a format command
- : (I do remember this: OPEN1,8,15,"N:BLAH,BL" or whatever.) It would rezero
- : the head, then fail. Now the head was positioned where it would find data
- : tracks again.
-
- That's doing it the HARD way! The easy way is simply to re-insert that
- cardboard head stablilizer that the drive came packed with (you DID keep it,
- didn't you? DIDN'T you???) Oh, well, an ordinary disk, inserted sideways,
- will accomplish the same thing: it physically pushes the disk head to where
- it needs to be...
-
-
- : Sadly, this behaviour caused some 1541s to be taken to the neighbourhood
- : "realignment" specialist -- realignment was accepted as the universal "cure
- : all" for ailing 1541s -- and usually ruined permanently in the process.
-
- Why ruined permanently???
-
-
- : Just random noise...
-
- Hey, don't sell yourself short -- random noise can be FUN! ;)
