Symptoms
You computer may stop responding (hang) when you attempt to hot detach either a CD-ROM or a DVD drive from the drive bay. Typically, you hot detach the drive by either clicking the Safely Remove Hardware icon in the status area of the taskbar or by using the device bay unlock lever.

Some computers may not support hot detaching the drive and may enter Standby mode automatically when you remove the device. If you resume the computer from Standby mode without removing the drive, the computer may hang until you remove the drive from the drive bay.
Cause
This problem occurs if you select UltraDMA (Ultra direct memory access) mode for either a CD-ROM drive or a DVD drive, if the drive is in the drive bay during a hot detach procedure, and if you do not reprogram the drive for the correct transfer mode. This leaves the drive and the controller in an "out of synchronization" condition; the Mode Sense command that is issued to the drive is lost, which causes the computer to hang while waiting for a response.
Resolution
To resolve this problem, obtain the latest service pack for Windows XP. For additional information, click the following article number to view the article in theMicrosoft Knowledge Base:
