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.
