Problemas com fita Sony AiT SDX-420C no debian

Bom dia pessoal, estou com um problemão, estou tentando realizar backup em fita só que eu não estou conseguindo configurar a unidade de fita.
Tenho uma unidade de fita Sony AiT SDX-420C inteface ide, o debian reconhece a unidade no /dev/hdd e seta para /dev/ht0, só que eu já tentei
usá-la e sempre dá erro, já tentei com /dev/st0, /dev/sg0 e outros e nunca dá certo, as vezes aparece a mensagem que não foi possível abrir o
dispositivo, e as vezes aparece a mensagem que não foi encontrado um
dispositivo tape. Já verifiquei que a fita aparece descrita no /proc/ide/hdd.
Resumindo, o debian reconhece a fita, mas eu não sei como fazer para ela funcionar. Agradeço aqueles que puderem me ajudar a configurar essa
unidade de fita. Segue abaixo a saída do dmesg.

saída do dmesg:
00000000
