Is there something I can tweak to make it work? It does work a little bit; I can get to the mode pages on the disk, was able to format it, (and with *lots* of repetitions, fdisk and disklabel it), etc. disk: IBM 0663W2H controller: aha1540B (an old one!) I'm running current from 10/5 or so... Although it acted the same with the 7/28 snap... (There are actually two of these in the system; they both behave the same. The other disk in here, ST41600N, has been working just fine for a long time.) About two thirds of the time I get "Bus dropped at unexpected time" during the probe; this one happened to work... The geometry reported is correct. Is this related to my antique aha1540?
