RAW partition on windows server.

We have a sever that hosts an app that uses a RAW disk to store data. The standard windows filesystem "all local drives" policy fails as it cannot access the drive. Even the OS complains about the drive not being accessible.

It looks like taking a image of a RAW partition isn't possible:

P687 of Symantec NetBackupTM Administrator's Guide, Volume I - "NetBackup does not support raw partition backups on unformatted partitions."

I was just looking for confirmation that am understanding this correctly and that there are no clever work a rounds that anybody has worked out.

Any help is greatly appreciated.
