You might want to check the partition map using dp. Sometimes SilverLining
doesn't create a BZB (block-zero-block).

Use dp and print the information for the slice in question

#dp /dev/dsk/c6d0s31
"/dev/dsk/c0d0s31" 9 partitions, 9 allocated [678574]
Command? p7
DPM Index: 7
Name: "A/UX Random", Type: "Apple_UNIX_SVR2"
Physical: 109134 @ 128, Logical: 109134 @ 0
Status:
        valid   alloc   in_use  not boot
        read    write
Slice 3 (clustered)
Regular UNIX File System (1)
Cluster:   0    Type: FS      Inode: 1
Made: [0] Wed Dec 31 16:00:00 1969
Mount: [0] Wed Dec 31 16:00:00 1969
Umount: [0] Wed Dec 31 16:00:00 1969
No AltBlk map
Command?

If it doesnt look like that then you can use the change command
in dp and add a BZB 

Command? c7
DPME Field? b
Cluster # [0]: 0
FS type (1=UNIX,2=EFS,3=SFS) [?]: 1
Root file system? n
Usr file system? n
DPME Field?

For more information on dp please read the man page. Also you can type 
a "?" once in dp and it will give you a list of the possible options.

Hope this helps

Antonio
