A "Stop 0xA0" Error Message in Windows XP

When you try to hibernate a Windows XP-based computer, you may receive a "Stop 0xA0" error message on a blue screen.

The reason being is if an integrated device electronics (IDE) time-out occurs during the hibernation process, the Atapi driver does not wait long enough for the primary IDE drive to come online.

If your computer has an ATA Packet Interface (ATAPI) hard disk that is larger than 137 gigabytes (GB), you may experience any of the following symptoms:

•	Your computer may restart instead of resuming from hibernation.
•	You may experience hard disk corruption when your computer enters either standby or hibernation.
•	You may experience hard disk corruption when Windows XP writes a memory dump file as a result of an unrecoverable Windows error (or Stop error)

Note If you experience hard disk corruption, you may also experience other symptoms including problems starting, restarting, or shutting down Windows XP, problems running programs, or problems opening or saving documents.

Possible Resolution

To resolve this problem, obtain the latest service pack for Windows XP.
