Dear managers:

Our DEC field engineer replaced a non system internal disk on DECstation
5000/33 running Ultrix 4.4.  I could not fsck the drive.  I typed 
"rzdisk -f known /dev/rrz3c to format drive and it apparently worked.

Next, I tried fsck drive to know avail.  Here is some output of a
typscript:

# fsck /dev/rz1c
** /dev/rz1c
BAD SUPER BLOCK: MAGIC NUMBER WRONG
USE -b OPTION TO FSCK TO SPECIFY LOCATION OF AN ALTERNATE
SUPER-BLOCK TO SUPPLY NEEDED INFORMATION; SEE fsck(8).
# /etc/chpt -q /dev/rrz1c
/dev/rrz1c
No partition table found in superblock...
using default table from device driver.
Current partition table:
partition     bottom        top       size    overlap
    a              0      32767      32768    c,d,e,f,h
    b          32768     163839     131072    c
    c              0    2069859    2069860    a,b,d,e,f,g,h

    e              0          0          0    a,c,d,f,h
    f              0          0          0    a,c,d,e,h
    g         163840    2069859    1906020    c
    h              0          0          0    a,c,d,e,f

# chpt -v -pa 0 1034930 /dev/rrz1a
/dev/rrz1a
chpt: /dev/rrz1a: blk 16: bad superblock -- run fsck
grep -i seg /usr/adm/syserr/syserr.petcar
rz1 at asc0 slave 1 (SEAGATE ST31230N         0510)

Is this drive which replaced a Quantum drive compatible with Ultrix?

Sincerely yours!!
