Bought from Atari Max. Dos version 4.3i.

Most issues are power related. Old atari PSU's are getting flacky.....
Yeah, I suspected that might be an issue. I'll try finding another one.

If this doesn't solve the problem, go for the modding version.
Here is were my knowledge ends, I have no to little problems with my PAL systems.
I actually did try one part of that mod (pin 4->pin 13 of the 74LS08). It hasn't seemed to make any difference. I'm tempted to try see if I can detect a faulty CPU with the blow-dryer test.

My 800xl with 4Mb/internal IDE (homebrew) and 2.5"HD works 100% error-free.

I wired the interface directly to the CPU.
Success,

Thanks for the tips. I tried looking for a drive with less than 1A load rating and found nothing. I'll be keeping my eyes open. Trying external drives on external power supplies netted me similar results, so I'm not optimistic going with a HDD will solve anything.
I'm still going to try to replace the PSU, but I'm left with the same results after the timing fix mod:
I can Initialize a disk (720SD),
but trying to H)copy to it gives me either error 169 or 139.
