We have a BIG problem: We have an AT&T 6386WGS running ISC 386/ix with a Priam ID130-AT 133MB Hard Disk, Western Digital WD1006-WAH Hard Disk Controller, 4MB memory, Versanet-40 ports card, Micom Ethernet card, IEV Video-overlay combo and a Paradise EGA-480 video card. The disk is partitioned with 8MB swap, 20MB "/" , 52MB "/usr" and 52MB "/usr2". Our problem is this: the disk died. It looks like an area under "/" went bad. We can boot to a point where most drivers are loaded and then we get a panic trap. The VTOC seems to be scrozzed as well. As far as we can tell, /usr and /usr2 are ok. We have some VERY important source code under /usr2 that for some stupid reason (cost of media) wasn't backed up for over a month and a half. Considerable development went on during that time and now we have a deadline to release the program and we can't get at it. Is it possible to mount the /usr2 partition on another machine running the same configuration? If so, how do we do it? If that isn't possible, I have heard of a company in Minnesota (I think) that specializes in recovering data from crashed disks. Does anyone know anything about this? Any help would be appreciated. Thanks in advance. *----------------------------------------------------------------------* #include <disclaimer.h> Jeff Johnson Global Information Systems Technology, Inc. 1800 Woodfield Drive Savoy, IL 61874 (217) 352-1165 ARPANET: jeff%gistdev%gistqa@uxc.cso.uiuc.edu UUCP: ...uiucuxc!gistqa!gistdev!jeff

If you can get to some machine running the same revision of the software
then use the standard "how to break into a pc running unix" technique.
Make a bootable floppy on some machine (dosn't matter what machine.)
put on a stripped down kernel (e.g. loose the device drivers where
possible) as much of the /dev directory as you can scavange (off an
old backup perhaps) /etc/passwd /etc/group /etc/init ... and
/etc/mount. /bin/sh /bin/login /bin/cpio and the like.
Having made this "scavengeing diskette" you should be able to mount
your old /usr /and /usr2 and archive them onto another source.
