The full backup fails with the error as below:


Storage device "HP1" reported an error on a request to write data to media.

Error reported:

A selection on device D: was skipped because of previous errors with the job.

Unless there is a physical fault, this is usually resolved by upgrading firmware and or drivers

To check for a hardware fault run a few passes of  HP's diagnostics routine

If this response answers your concern, please mark it as a "solution"
