Windows- delayed write failed (error)

I have been having failed backup jobs for the past few weeks. The Complete error is Windows- delayed write failed. Then it explains "Windows was unable to save all the data for the file \Device\CDrom1\Veritas\B2D\B2D000009.bkf. The data has been lost. This error may be casued by a failure of your computer hardware or network connection. Please try ro save this file elsewhere."

I have windows 2000 Server Sp4. I am backing up to an internal IOMEGA Rev Drive.
This message keeps popping up after every few hundred KB's. Anybody here have a Clue?

    Hello,

    -- Are you getting any event id's in the application event log?

    -- Are you backing up databses like Exchange or SQL?

    -- Are you using AOFO to backup, if yes, then try disabling it.

    Hello,

    This is not exactly relevant to your environment however please try the suggestions in the following technote.
