Franko:
Actually I was asking Claw22000 :-). I know the ones you were trying to install, and that weren't working, on an A1200 were 20gig+ 2.5" IDE. It seemed to be the same problem I was having, that the WD800BEVE drive wouldn't work on my A1200. But, I think it may have been a matter of that drive being DOA, much the same as it sounded like happened with your two 20gig+ drives that didn't work, and not some issue with installing it in an A1200. I think modern HDs can get killed rather easily if someone mishandles them along the way. Because now I tried a WD3200BEVE and it works! Same model, just different capacity. I didn't do anything differently than with the previous one when installing. Good thing too, cause I need an HD to web browse on my 1200 again, especially since my old PC just died.

Neither myself nor Franko has a Win PC with USB. But that wouldn't have helped unfortunately because we had been stuck with dead drives. :-(
