i have 2 810 disk drive one went out while in storage and would not turn off. no matter how long it sat but the other was still OK well while using it today i started getting boot error on every disk even the good ones and then it started doing the same thing the other was doing so i narrowed it down to the side board started switching around like numbered chip and ended up with one kinda working board i still only get boot error any suggestions on how to fix this?

Well, floppies do get damaged. I have a few where the read-write head scored a circle on the surface. Plus the oxide can build up on the head then flake off onto the diskette. They seem to get "tired" after 25 years of sitting there too. Finally, sometimes the sector that gets written is not verified as correct after being written. 8 weeks later, you try to read the disk and thud.

hmm, in that case.. either...
bad disk drive is spinning at the wrong speed (most likely) or
tracks are way off on the bad guy

If you have a spare floppy, format it on the "bad" drive.
If it looks great when you access it on the bad drive, then it's one or both of the above.

Time to give up on those drives, I think. I have a diskette drive that won't read the floppy unless I put extra weight on the read/write head. The spring that puts pressure on the head has become weaker with time. That kind of thing is just too much trouble to repair.

Could hit up ebay or

There are alot of Atari 400/800 systems and accessories out there. If you talk to your prof/instructor, perhaps you can get an extension for your demo so you can get a new drive. Wont hurt to ask.

As for fixing it, talk to the guys over here or at myatari and see if there is a guide to recalibrate the drive. I am not sure what it takes, but I would be familiar with a DMM/VOM and maybe have access to an OScope (again, not sure if thats even needed).
