Was there some sort of power failure? Were things running hot? Has
a sudden shutdown happened previously?
and when I went to restart I got a reassuring BONG
Ok. So your CPU, memory, and buses are probably ok.
and the blue background of the desktop popped up sans icons. Mouse doesn't
work
Perhaps a HD failure.
Ran Applejack from Open Firmware
No. You ran AppleJack from the root account of OS X, while booted
into Single User Mode.
and it said something about incorrect number of thread records,
invalid volume file count.
The files system on your HD has been corrupted, perhaps the data areas also.
It also says that there is a missing directory record and Applejack
was not able to fix
the disc.
AppleJack is simply a shell script that runs various utilities.
fsck, aka Disk Utility, was unable to repair the disk volume.
Any idea of what to do?
As others have said, try a different tool. You can try booting on
your OS X DVD, or an external drive, and running a Repair Disk pass
with Disk Utility -- but I doubt that will work, as fsck has already
failed.
The next best tool is DiskWarrior. Fsck tries to repair the file
system in-place. DiskWarrior is a bigger hammer - it will try to
rebuild the file system from scratch, making a whole new one.
Of course, this doesn't say much toward the actual cause. If your HD
is failing, then the only point of doing the repair work would be to
get it to the point you can make a backup...
