[QUOTE=mciahel;2568062]The Sata controller of the 8237 southbridge is identical to VT6421 (which was designed for add-on cards). Yes, these do have problems with SataII drives.
Unlike HDDs from WD or Seagate, Samsung HDDs can not be jumpered to SataI operation. You need to connect it to a compatible controller and then use ESTOOL to reconfigure the drive.
The alternative is to replace the VIA based controller card by something else, for example a Silicon Image based controller card.
Thanks for clearing that up, I had no idea. You are a real guru
I’m happy with the new server I ordered, but this will help others who run into this problem!
EDIT: I’m wondering now though, if the problem was with the chipset on the SATA controller card, why did it work fine when I plugged the card into a different PC?
