On 7, I have: ad0: 152627MB <MAXTOR STM3160212A 3.AAJ> at ata0-master UDMA100 which seems correct. as I always had since I had this mainboard (with 6.2). I've also replaced the cable with a brand new one, with the same results. So, what's wrong? I wonder if 8 is exposing a HW problem that I should be worried about or simply something wrong was introduced. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
