I'm running an SBS 2003 server. Im using the windows backup program to backup to a Seagate eSATA 500 GB HD. I get the Delayed Write Fail sometimes when the backup is running. I've read a lot about this problem, but I still can't seem to find an answer. Microsoft said to adjust the SystemPages value in the registry to 7FFF, but it was already at C3000. Another site said to disable Write Caching on the HD, but the option to do so is grayed out. Any suggestions?
