NTBackup Error: C: is not a valid drive
- by Chris
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:
Open NTBackup
Select Backup Tab
Tick the box next to C:
Ensure Destination is 4mm DDS
Media is set to New
Press Start Backup
Choose Replace the data on the media and press Start Backup
NTBackup tries to mount the media
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:
