Hi, Some preliminary testing that I have done...the WD20EARS (2TB advanced format drives) actually presents emulated 512byte sectors to the host o/s.
The drive documentation indicates that jumpers 7-8 should be enabled if the o/s does not support advanced format drives - the drive still present 512 bytes sectors. I have attempted to raise a support ticket querying this, and how one can disable 512byte sector emulation in the drive (perhaps through a firmware upgrade) but I have not received any response to date. Hopefully is enough people raise support tickets, WD may release firmware that allows the drive to natively present 4k blocks. Other doco indicates several other jumper combinations - all do not seem to make the drive present 4k byte blocks. Perhaps someone internal to sun that has a relationship with WD may be able to shed some light on this? It would be fantastic to find out that I was just doing something wrong -> then I can get the drives to be seen on 32bit systems (ie - our embedded kit for osol, velitium) Tested using b133 (64bit intel).
