We had many issues with Seagate drives and and S/M boards with the 
onboard Adaptec scsi controllers. Seagate offered no help other than to 
suggest putting in a network card (in lieu of the onboard) and/or 
disabling SMP; neither solution was acceptable so we switched to 
IBM/Hitachi drives and the problems disappeared. By the way, the 
problems manifested themselves in those servers where we had more than 
just one hard drive installed. This was even after updating to the 
latest firmware etc; Seagate insists no problem with their drives 
although other drives work perfectly well. YMMV

I do see you say you tried other harddrives .. which ones did you use?
