Hi Sirs,

I'm having lots of troubles with my backups, and i hope someone can HELP ME.

Here we have two machines with the same configuration.
Pentium 100, 32 Mb RAM, HD 2.0 gb SCSI and an EXABYTE - 4mm Cartridge 
tape drive

 Running FreeBSD 2.1.

That's the problem i have.
I can write to the tape, but i can't read anything from the tape.

When i try to restore a backup, using tar for example my system crashes.
The computer tries to access de tape, and nothing happens, waits about 
two minutes and then the system CRASHES.
Here follows the error msg the system sends to me:

	ahc0:target 3,lun 0 (st0) timet out
	st0(ahc0:3:0):BUS DEVICE RESET message
		      Queued.
	st0(ahc0:3:0):TARGET Busy
	ahc0:A:3:no active SCB for reconnecting 
		 target - issuing ABORT.
	SAVED_TCL == 0x30
	ahc0:target1,lun0(sd0) timed out

By the way, I tested the restore on both machines, using CPIO and TAR. 
But everytime i try to access something from the tape to the HD, the 
system crashes.

Any help or information will be useful. I need to soon this problem as 
soon as possible.

Please, I'll be very glad if someone help me.
	 
Thanx a lot.
