I tried to emulate ACSI hard drive with Hatari (by following instructions in http://hg.tuxfamily.org/mercurialroot/hatari/hatari/raw-file/tip/doc/manual.html), but it got me nowhere. The best I achieved was that drive was detected, I could format&patrition it (using AHDI 5), but after trying to write anything to it (driver) it got corrupted. I also tried AHDI 6 and Hddriver 9.
