SYMPTOMS

You have an Advanced Technology Attachment Packet Interface (ATAPI) hard disk. For example, you have a DELL PowerVault RD1000 removable drive. The hard disk can work in a high speed Ultra Direct Memory Access (UDMA) transfer mode. When you start your computer into the Microsoft Windows Preinstallation Environment (Windows PE) 2.1 from the hard disk, Windows PE 2.1 takes a long time to start. Additionally, you experience a slow performance on the hard disk after Windows PE 2.1 has started.

CAUSE

This problem occurs because the ATAPI hard disk is identified incorrectly in Windows PE 2.1. This causes the hard disk to work in the Programmed input/output (PIO) Mode 1 transfer mode.
