SYMPTOMS

After you apply the updated Atapi.sys driver on a computer with a hard disk drive larger than 8 gigabytes (GB) that is connected to a Promise Technologies Ultra 33 PCI bus-mastering controller, the drive may still be reported as only 8 GB by Disk Administrator.

CAUSE

On computers configured to use a Promise Technologies Ultra 33 PCI bus- mastering controller, the following conditions must be true:

  • Version 1.3.5 or later of the Promise Technologies driver must be used.
  • The updated Atapi.sys hotfix must be installed.
  • The IDE channel must be disabled in the computer's BIOS so that the LBA EIDE feature in the BIOS on the Promise card can control access to the drive.

RESOLUTION

To see a hard disk drive that is larger than 8 GB and is connected to a Promise Technologies Ultra DMA PCI controller, the following conditions must be true:

  • The IDE channel to which the drive would otherwise be attached on the motherboard must be disabled in the computer's BIOS.
  • Use the latest driver for the Promise Technologies Ultra DMA bus- mastering card. For the entire drive to be accessible under Windows NT 4.0, version 1.3.5 or later of this driver must be installed.
