When I set up my own SD-HDD solution based on the wonderful ACSI2STM project, I found the hard drive was becoming corrupted pretty soon after setting it up. I thought it might have been my dodgy soldering or something funny about the way I had everything set up. Turns out I simply hadn’t heard about Bad DMA. A local Atari enthusiast meetup later and a solution was proposed; swap the 68000 chip for a newer, lower power and subsequently less noisy version.

It worked!
