Erro no NTBackup: C: não é uma unidade válida

Question

Estou tentando usar o NtBackup para fazer backup do C: Drive em uma máquina do Microsoft Windows Small Business Server 2003 e obter o seguinte erro no arquivo de log:

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.

Estou usando um novo disco SATA Quantum Dat-72 com uma fita nova (tentei algumas fitas).

Eu faço o seguinte:

1. Abra o NTBackup
2. Selecione a guia Backup
3. Marque a caixa ao lado de C:
4. Garantir que o destino seja 4 mm DDS
5. A mídia está definida como Novo
6. Pressione Iniciar backup
7. Escolha Substituir os dados na mídia e pressione Iniciar backup
8. O NTBackup tenta montar a mídia
9. A mensagem de erro mostra:

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.

Ao verificar o log, encontro o seguinte:
