4500.0. "Recovering from a Disk problem" by KYOA::MIANO (John - NY Retail Banking Resource Cntr) Fri Feb 08 1991 12:33

My 2500 has the 40MB disk that came with it and an 84mb SCSI drive
that I added to it.  Recently I noticed a lot of strange stuff
that was the result of disk corruption.  I copied everything from the 40MB
drive to the 80MB drive and rebuilt the system disk from scratch.

Unfortunately my only copy of my Mountlist file was on the other
hard disk (stupid me).  Well I know that I have 4 partitions on the
drive of equal size so I tried to create a mount entry for the
first on.  After a little trial an error I went from "No a Dos Disk"
to "Validating" when I did an info command.  So far I have not
been able to mount the first or any other partition.

HELP!!!!!!!!!

Does anyone know how I might recover from this or am I S.O.L.

4500.2QBTools CurseDICKNS::MACDONALDVAXELN - Realtime Software PubsFri Feb 08 1991 13:5421
    Well, I experienced a similar problem last night. I noticed that some
    of my icons were trashed or not displaying at all. I also discovered
    that I was getting read/write errors, programs not executing and so on.
    
    My solution:
    
    1. Build a small fire in the back yard.
    2. Get it nice and hot.
    3. Toss Quarterback Tools into it.
    
    I am convinced that my recent use of QB Tools V1.3d did a real serious
    number of both of my drives.
    
    So, I reformatted both drive last night and restored all the files.
    Unfortunately, some of the restored files are corupted from the last
    time I used V1.3c.
    
    This weekend's task is to check all my files, then back up the drives
    again.

4500.3QBTools or...DECWET::DAVISSay what?Fri Feb 08 1991 15:0623
    I have been hearing a lot of cursing of QB Tools.  I have also heard a
    lot of praise for "Tools".  I have used QB Tools version 1.3a for the
    last couple of weeks to undelete files and restructure my partitions
    while converting from my A500 to A2000 and have not had a glitch.(my
    largest partition is 140Meg). No lost icons, no drive trashing, no
    nothing.  It does, for me at least, what it was designed to do.  I
    spoke with two other persons on Internet who were experiencing problems
    with QB Tools,  specifically, and other utilities/applications in
    general.  Both found that they had a virus on multiple files.  I can't
    remember whether it was Xeno, or some other varient but the virus was
    contracted from a version of Lharc(or some Lharc clone) which they
    copied from someone or downloaded from a FTP site. This is not to say
    that this is your problem but it might be worth a look.  They both ran
    "Berserker" from one of the latest Fish disks and cleaned up their
    files.  Both are happy campers now.   One other thing, when I had my
    A500 with 3meg Ram and 200meg hard drive I couldn't get QB Tools to run
    consistently.  It didn't trash my files or anything like that it just
    wouldn't start the reorganization.(I was running a Supra SCSI
    controller).  With my A2000 and GVP SCSI+Accelerator and 9megs RAM I
    haven't had ANY problems.  Maybe changing the memory settings before
    you start whatever action you are trying to accomplish might help.

>Have you tried disksalve or Quarterback tools?

Neither one.  I assume that QB is something you buy, right?

    How does the Xeno manifest itself?
4500.6Check VirusX docs.DECWET::DAVISSay what?Fri Feb 08 1991 17:277
    I do not know for sure, but I will inquire.  According to the guys I
    spoke with apps/programs that ran before infection usually crashed or
    hung afterwards. I believe in the Docs for VirusX there is a description 
    of the various viruses.

4500.7I'm sort of happy nowKYOA::MIANOJohn - NY Retail Banking Resource CntrFri Feb 08 1991 21:0719
Well I managed to recover.  Here's how.

1) I used DISKSALV as suggested

This produces an unbelievable mess of file fragments.  

2) I did a "SEARCH" on all the files for strings in the
MOUNTLIST.HD file.

3) I then was able to create a mountlist.hd file.

4) I was able to mount the partition containing the mountlist file.

5) The mounstlist.hd file was now accessable so I used it
to mount the other partitions.

6) I was then able to diskdoctor and recover most everything.

WHooooooooooooo.
