[osp-datensicherung] Probleme mit Datstreamer SONY SDT-5200

Hallo Liste,

ich habe einen ausgemusterten SDT-Streamer über eine Adaptec 2940 in meinen 
Rechner eingebaut.
Keine weiteren SCSI-Geräte am Bus; Jumper am Streamer auf ID:0, Parität und 
Terminierung; Einstellungen im Adaptec-Bios konservativ.

Allerdings lassen sich auch nach Cleaning keine DDS[1-3] Bänder beschreiben.
Karte muss sich IRQ 10 nicht mit anderen Geräten teilen.
Modul aic7xxx wird verbose im Betrieb geladen.

Und Schicht im Schacht :-(

Kann mit jemand einen Tipp geben, was ich falsch mache?

Danke,
