Amiga 1000 drive issue
« on: September 12, 2011, 05:32:31 AM »
Hi, i've got a weird problem with an amiga 1000 with faulty stock  drive (tamagawa). I tried to swap  the original one with a panasonic then a  chinon 354 but the machine seems to ignore the diskchange. The only way to read a floppy disk is to insert it *before* reset or powering up the machine, if you try after the kickstart request or the kickstart screen (after loading kickstart at boot on reset or  powering up) there is no drive activity, it seems to miss the diskchange signal. I tried to swap the CIAs but nothing has changed.
The only thing i can do is load kickstart.
Can i get some results swapping paula?
Help me please.

Thanks.

If those drives are PC drives, that's normal.
They don't use the same diskchange setup.
They should be able to be nodded tho.

Random thoughts:

Possible your power supply is starting to go. May need its electrolytic caps replaced. I have an A1000 that does something similar if I have too many things hooked to expansion bus.

It's also possible you need to clean the tiny switches just inside the mouth of the drive on the left. Spray 'em down with contact cleaner and actuate several times with your finger to work the cleaner in.

Old Amiga drives can be finicky with mixed media. I have an internal A1000 drive in fact, that doesn't like high density disks, even if they've been formatted as double on another system. This same drive is so picky that it doesn't even like certain original C= Kickstart or Workbench disks!

I do not know if this could be the problem. The A1000 boot disk has the OFS format and
might not be recognizing a ffs disk. I have not used a A1000 but you might try making a new boot disk for the A1000 with a upgraded file system or making a new disk with the OFS to try to see if that is your problem.
