Does NetBSD have broblems with this disk?
I get something like that at boot time:

 sd0 at scsi0 slave 0
 sd1 at scsi0 slave 1
 sd2 at scsi0 slave 2
 scsi0 targ 6 abort from icmd phase=0x49, ssts=0xb2, ints=0x0
 scsi abort gave up after 1000 tries (startlen=1048 len=1047)
 scsi abort gave up after 1000 tries (startlen=1048 len=1046)
 scsi abort gave up after 1000 tries (startlen=1048 len=1045)
 scsi abort gave up after 1000 tries (startlen=1048 len=1047)
 sd3 at scsi0 slave 6
 .
 . 
 .
 changing root device to sd0a
 sd0:scsii sense class 7, code 0 =, key 2
 sd0 WARNING: I/O error, using old default partitioning
 panic: cannot mount root

I can disklabel the disk, copy an copy back files .
Sometimes I had problems to dd the miniroot-12.fs to sd3a.
After a while the system hung up completely.

The disk run for a year under my eyes without any problems under HP-UX 
9.00A. And I also tested the disk with a 360, 380, and 433T.

	Can anyone analyse this symptom?

	Thanks Andreas
 
PS: The hp disktab says that the disk has/uses/supports? ZBR.
    Does anyone know this 'feature'?
