I had to give up on my Serial to IDE convertor so now I'm using IDE again (I couldn't stand the 1.3 MB/sec transfer rate with the SiI3112 so I reinstalled using IDE). Anyway, I too am looking for a fix for this but it looks to me like very little if anything has changed since 2.4.x. My system also crashes (to say the least! I lose all access to my HD) when I try hdparm -X66 -d1 /dev/hdg. -- Devin
