Merkey" Cc: "Randy.Dunlap" , Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, > It's not on a raid controller. The machine has a PIIX3 ide > controller and a > AHA-2940UW scsi controller. Both exibit the same problem. Actually, no: To fully use 160GB ATA drives, whatever device is on the other end of the ATA bus needs to actively support 48-bit address mode. In for the two cases you tried, that means IDE: The kernel IDE driver needs to support 48-bit addresseing to support 160GB. SCSI: The firmware in your IDE<->SCSI Adapter needs to support 48-bit addressing. So, while the symptoms are the same in both cases the problem is actually in two completely different places. Most probably, you can't do anything about the IDE<->SCSI adapters firmware; however, you can do something about the linux ATA driver: code is in the 2.4.19-pre tree, it went in with 2.4.19-pre3.
