Hi all,
Looks like I spoke too soon about getting my AT working. I think something's wrong with the hard disk or the controller. Sometimes the computer boots just fine, other times it fails with a 1780 error. Before the error code pops up, the drive attempts to read for ~2 seconds (which repeats 4-5x). In a side note, the drive made the same exact noises when I accidentally plugged the data ribbon cable into the wrong header on the controller. When the system wouldn't boot last night, I tried to low-level format the drive with SpeedStor and it failed with 0x80 controller error. SpeedStor was however able to perform a regular format. I was able to transfer a system over to the disk drive and it was able to boot on its own again. When I tried to turn the system on this morning (which was a few hours later!), the same 1780 error began occurring again. I was able to boot off a floppy disk which let me run SpeedStor. All non-destructive diagnostics passed but the system still wouldn't boot. I'm kinda scratching my head at this point. I'm not sure if the problem is with the controller, as I have a late model AT with 11/1985 BIOS but the computer came with the first generation disk controller. The only other reason why I think it may be related to the controller my 3.5" disk drive occasionally gives me read errors on known good floppy disks that work perfectly in my other computers. Anyways, I'm not really sure how I should proceed with this, so any help or tips would be greatly appreciated Thanks again as always.
