I have this:

> sa0 at ahc0 bus 0 target 3 lun 0
> sa0: <HP C1537A L708> Removable Sequential Access SCSI-2 device 

Connected to this:

> ahc0: <Adaptec 2940 Ultra SCSI adapter> port 0xd000-0xd0ff mem 
> 0xe9511000-0xe9511fff irq 18 at device 10.0 on pci0 aic7880: Ultra
> Wide Channel A, SCSI Id=7, 16/253 SCBs

When I try to write to it with amanda I get this in dmesg:
