 OS 10.1.5, Warcraft II and the amazing Read Only File System
Fellow BSDers and OSXers I enclose a story of infinite intrigue for
your reading pleasure. Twas a fine monday and I was installing some
old games on my Mac Powerbook 400 running Mac OS 10.1.5. All was well
Until I went to install Warcraft II then there was a full System lock
up(ie no Command-option-escape kill box) no worries I thought and
restarted the system. After Rebooting happily I got to my login screen
and was surprised to find that the mouse did not work. Hmmm. Have I
killed the mouse I thought and rebooted with the aple diagnostic CD,
no everything passed. Hmmm I was becoming Concerned. Reboot with the
OS9 CD It did restart and booted off the cd. However It told me that
the Volume Mac OS9.2.1 was damaged and completely refused to mount my
Hard disk. This was not a good outcome I thought. Disk First Aid still
Worked though and Told me the Disk had a. Overlapped extent
Allocation(file 774353d) b. Missing Thread record (id=700900) c. Keys
out of order. Then it promtly stopped. OK i thought I should repair
this volume. Clicked repair it said the same thing. Clicked Verify
Again same thing. Hmm I thought and rebooted off the OSX installer CD.
I ran First aid from the OSX CD and got the same problems. Now I was
starting to freak. I knew that the Disk was HFS Plus formatting and
therefore should boot in OS9. I thought I would restart off my HFS+
OSX partition. It booted again but again no mouse was there. I logged
in as root an managed to get myself a terminal using just the keyboard
Then I discovered the AWFUL TRUTH, MY HARD DISK PARTITION WAS READ
ONLY. I coudl not write files to the disk, Make directories or even
use man as It needed a /tmp directory that wasnt present.
I started throwing my limited knowledge of Linux at it
(PS. these are as direct as I could get copying them down and
transcribing them here.)
#root>mount
/dev/disk0s9 on / (Local)
devfs on /dev (Local)
fdesc on /dev (union)
<volfs> on /.vol (read only)

#root>joe /etc/fstab.hd
/dev/hd0a /      ufs rw 1 1
/dev/hd0e /var   ufs rw 1 2
/dev/hd0f /usr   ufs rw 1 2
/dev/hd0d /tmp   mfs rw,-s=12000,-b=8192,-f=1024,-T=sd660 0 0
"Right?!?!!??" I thought not understanding why my supposed 1 drive
with one HFS+ partition was displayed at 4 separate partitions the
majority of them UFS.

next step "fsck" by the way I could not fsck any of these supposed
drives (hd0a through to f)
#root>fsck /dev/disk0s9
** /dev/rdisk0s9
BAD SUPER BLOCK:MAGIC NUMBER WRONG

LOOK FOR ALTERNATE SUPERBLOCK [yn]y

SEARCH FAILED YOU MUST USE THE -b OPTION TO SPECIFY THE SUPERBLOCK

ok I thought ls'ing the sbin directory there is a fsck_hfs i'll try
that
#root>fsck_hfs /dev/disk0s9
** /dev/rdisk0s9
** Root File System
** Checking HFS Plus Volume
** Checking Extents Overflow File
** Checking Catalog File
   Overlapping extent allocation (file 774353d)
   Missing thread record (id = 700900)
   Keys out of order
then the command prompt.
by the way the last entries fot the System log are thus:
/sbin/autodiskmount[92]:disk1s0s2   ???  hfs  no  no  GDI
/Volumes/GDI
/sbin/autodiskmount[92]:UnmountDisk ('disk1s0s2') failed 16 device
busy
mach_kernel: disk1s0s9 is write locked
/sbin/autodiskmount[92]:disk1       ???  cdda no  no  AudioCD
/Volumes/AudioCD
/sbin/autodiskmount[92]:disk1s1s2   ???  hfs  no  no  Warcraft II CD
/Volumes/Warcraft II CD

hmm I thought now I am lost, gave up and went to bed vowing to post
this message the next day.

In summing Up I am currently left With a PB 400 with OS 10.1.5 and
supposedly 9.2 dual boot on a single 10Gb HDD with only one HFS+
partition which will Load OSX ok(read only) but not mount the disk in
OS9
Please if anyone can help me fix my problem, get my computer into OS9,
explain what the weird entries in fstab.hd and mount are or tell me
what half the /dev/rdisk or disk files actually do I would be greatly
in appreciation
Many thanks for reading this post and do not hesitate to posrt any
information that you may have
thanks

Sorry I can't help you with your problem. But I think this is the case

ultimate evidence that Microsoft sucks and is full of crap. ;)

Boot from your OSX volume -
hold down the Cmd & S keys as soon as you hit the power button.
follow the instructions on screen to fsck and mount /

shutdown -r now

you may need to repeat this 2 or 3 times if it's real bad...
