[comp.os.os9] OS/9 file system crashed, need help!

aras@ecerl3.ece.ncsu.edu (Caglan M. Aras) (03/14/91)

We have a MATRIX VME OS/9 system, version 2.3 A few hours ago,
a fellow student typed the following command:

DEL .*

in his subdirectory while he was the super user. Somehow, the
whole filestructure in the hard disk was wiped out! This seems
to be a serious bug in OS/9, it recursively deleted all directories
by using the .. pointer to the parent of the directories.

Is there anyone out there who knows about tools that we can get
or download to read the deleted directories? Or at least read 
sectors? Right now, all of our old work is on there and some of
it was not backed up. Your help will be greatly appreciated.
