Driver error help needed! (esp0:4:0)

Hi!
Does anyone know how to fix this? I've got netbsd on a jaz disk. The
driver barfs when moving files and directories from jaz partitions onto
a zip data disk. Both the jaz and zip partitions (useable netbsd
unmounted partitions) are clean with fsck -fy. The only thing i know is
that the 4 in (esp0:4:0) refers to the scsi address when using the
installer.

# mv file1  /zip/usr
sd2(esp0:4:0): soft error (corrected), info = 1791975 (decimal), data =
00 00 00 00 17 01 00 00 00 00 3a 1e 01 39 79 01 00
# mv smalltalk-1.1.5 /zip
sd2(esp0:4:0): soft error (corrected), info = 1593612 (decimal), data =
00 00 00 00 18 01 00 00 00 00 2b 2e 01 bc 01 40
sd2(esp0:4:0): soft error (corrected), info = 1657001 (decimal), data =
00 00 00 00 18 01 00 00 00 00 3a 05 2e bc 01 40
# mv vtwm-5.3 /zip
sd2(esp0:4:0): soft error (corrected), info = 1657001 (decimal), data =
00 00 00 00 17 01 00 00 00 00 36 3a 01 2e 6c 01 00
# mv xpaint /zip
sd2(esp0:4:0): medium error,           info = 1857631 (decimal), data =
00 00 00 00 14 00 00 00 00 3b d5 01 31 7e 64 00
mv: xpaint/color.c: input/output error, info = 1857949 (decimal), data =
00 00 00 00 14 00 00 00 00 3b d7 01 31 7e 64 00
...[and on, and on...]  

NOW, i've put a mount command in rc.local to automatically mount all jaz
partitions, but when i boot multiuser i get  this error:
...mounting jaz partitions /vol-f, /vol-g, & /vol-h.
sd2(esp0:4:0): soft error (corrected), info = 1007718 (decimal), data =
00 00 00 00 177 01 00 00 00 00 1f db 01 30 07 01 00

And when i unmount all partitions, i get this error:
/scripts/jaz_umount /* umount script to get off jaz paritions */
sd2(esp0:4:0): soft error (corrected), info = 1007718 (decimal), data =
00 00 00 00 0c 80 00 00 00 00 1f db 01 30 2e 01 00


Any help is appreciated!
