I'm trying to use NtBackup to back up the C: Drive on a Microsoft Windows Small Business Server 2003 machine and get the following error in the log file:

Backup Status Operation: Backup Active backup destination: 4mm DDS Media name: "Media created 04/02/2011 at 21:56"

Error: The device reported an error on a request to read data from media. Error reported: Invalid command. There may be a hardware or media problem. Please check the system event log for relevant failures.

Error: C: is not a valid drive, or you do not have access.


The operation did not successfully complete.


I'm using a brand new SATA Quantum Dat-72 drive with a brand new tape (tried a couple of tapes).

I carry out the following:

  1. Open NTBackup
  2. Select Backup Tab
  3. Tick the box next to C:
  4. Ensure Destination is 4mm DDS
  5. Media is set to New
  6. Press Start Backup
  7. Choose Replace the data on the media and press Start Backup
  8. NTBackup tries to mount the media
  9. Error Message shows:

The device reported an error on a request to read data from media. Error reported: INvalid command. There may be a hardware or media problem. Please check the system event log for relevant failures.

On checking the log I find the following:
