What am I doing wrong?  I have an (aha0:4:0): "EXABYTE EXB-4200c 217"
type 1 removable SCSI 2 and I able to dump and restore all my files
systems (/ , /var, and /usr/ports) except /usr.  I'm using FreeBSD
2.2.2  and I use the command "dump 0auf /dev/rst0 <file system>".  I use
the command: "restore if /dev/rst0" to restore my file systems.  But
whenever I try to restore my /usr file systems after and successful dump
I get this message " Tape read error while restoring <directory file -
name unkown> continue [yn]"  Wether I answer yes or no this process
hangs.  I tried new tapes and I've booted as single user then dumping my
file systems and get the same results.  I can tar my whole file systems
to tape without any problems, but I would preferr to use dump.  Also mt
status reads:
$ rksh mt status
Present Mode:   Density = X3B5/88-185A Blocksize variable
---------available modes---------
Mode 0:         Density = 0x00         Blocksize variable
Mode 1:         Density = X3.136-1986  Blocksize = 512 bytes
Mode 2:         Density = X3.39-1986   Blocksize variable
Mode 3:         Density = X3.54-1986   Blocksize variable

When I run dmesg my tape drive reads:

(aha0:4:0): "EXABYTE EXB-4200c 217" type 1 removable SCSI 2
st0(aha0:4:0): Sequential-Access density code 0x13, 512-byte blocks,
write-enabled.

Should these match?  Please help!  Thanks!
