- Summary: the '9' partition on the 1st XDC disk always dies

- This is getting to be a bad habit here. I have had the 3rd power
- outage in a year. Generally, the 3B2 is robust enough to survive
- this. Even when it comes up, the disks are barely munged. Execpt for
- one partition. Grrrrr.
-
- The "9" partition on the first XDC drive (/dev/dsk/cXd0s9) always gets
- corrupted. The disk is a Maxtor 2190 formatted for 120Mb, although
- the prfconf thinks it's just a 72Mb drive. Here's the partition info:
- -----------------
- * /dev/rSA/disk3 partition map
- *
- * Dimensions:
- * 512 bytes/sector
- * 18 sectors/track
- * 15 tracks/cylinder
- * 270 sectors/cylinder
- * 1024 cylinders
- * 1022 accessible cylinders
- *
- * Flags:
- * 1: unmountable
- * 10: read-only
- *
- * First Sector Last
- * Partition Tag Flags Sector Count Sector Mount Directory

- 8 0 00 270 100170 100439 /usr/src
- 9 0 00 100440 100170 200609 /scratch
- a 0 00 200610 75330 275939 /usr/local
- ---------------
-
- and /scratch always gets killed. Fsck bitches like this:
-
- ---------------
- /dev/rdsk/c10d0s9
- Size check: fsize 0 isize -2139082149
- ---------------
-
- So, I know that the superblock is trashed. Does anyone know fsdb well
- enough to get me back on my way? How about a way to preserve the
- superblock (maybe a DD copy) that I can always put back in case of
- emergencies?
-
- It't getting so that I am wondering whether to use that 50Mb partiton
- at all!
-
- Any help would be greatly appreciated!
