I've had this problem with HP DAT drives too. I've found that you can  
sometimes "reset" the SCSI for the tape by executing "restore i" before  
using "restore if /dev/nrst0". This causes an attempted access to the (on  
my machine) non-existent Exabyte interface, and seems to be equivalent to  
applying a "swift kick" to the machine. I've discovered that applying this  
procedure once after rebooting the machine seems to fix things till the  
next time the machine is rebooted. Give it a try.
