[comp.sys.ibm.pc] Problem with the Norton Disk Doctor

mju@mudos.ann-arbor.mi.us (Marc Unangst) (04/23/89)

Rather recently, I decided to stop running MINIX on my hard disk and format
that partition for DOS.  Because I didn't want to have to back up and
then restore the contents of my other partition, which would have taken
well over 2 hours, I decided to leave the partition structure the way
it was (17MB C:, 3.9MB D:), and just reformat the second partition
for DOS.  So, I twiddled the Partition Assignment Bit in IO.SYS (using
Zenith's CONFIGUR utility) to Manual, and then ran ASGNPART to assign
Partition 2 to drive D:.  (I'm running Zenith MS-DOS v3.1.)  Then, I
used FORMAT.COM to format drive D:.  So far, so good.  I can now use
drive D:, and everything else works fine.  However, when I start up
NDD, it pops up the "Analyzing Partition Table..." message, takes
it down (as normal), and then crashes so hard that even the three-finger
salute doesn't work.  I have to cycle the power to regain control of
my machine.  The only drivers I have in my CONFIG.SYS are those for
a ramdisk, and DoubleDOS's ANSI.SYS replacement (DBLDANSI.SYS).  When
I tried rebooting without a CONFIG.SYS or AUTOEXEC.BAT (i.e., without
assigning partition 2 to drive D:), NDD didn't crash.  It put a
D> prompt at about line 1, column 50.  For some reason, DOS then thought
that there were NO files on ANY disks.  When I typed DIR, I just
got a "File not found" message.  Whenever I tried any external command,
it just said "Bad command or file name", without even accessing the
disk.  I have to reboot (soft) to get things back to normal.

I'm getting desperate here.  I usually run NDD's full surface check
every week, to make sure the disk is okay, and I can't do that now.
I haven't been able to check drive D: at all, and that concerns me:
It has a bad cluster on it, and I'd like to lock it out before it starts
to corrupt files.

Depending on the version of Norton you're running, there is a problem
with the utilities.  As I remember, 4.5 had problems when used with
dos and *ix type file systems.  I'm not sure what the problem was, but I
seem to remember from a posted note that it dealt with the trashing
of partitions.  I think
that a letter was to be sent to registered users informing them of 
problem, with info on what to do.  This may or may not be related to 
what you've seen, but sounds like it might be if you're using 4.5.

You should be using Norton Utilities program files date stamped Jan 3 89.
These were an update that you should have received a letter about. Call
them.

	One thing I have discovered about NDD is that it will lock up (Divide 
Error sound familiar??) when one runs it on a non-bootable partition (my AT 
clone only supports one Dos partition).  
	When you start NDD up, it runs thru some initialization checks of the 
boot record, etc.  At this point, it will display error messages saying that it
has found non-standard "stuff" and do you want to fix it?  Well, your
answer should be 'NO'.  It sorta makes sense:  if it's not your booting
partition, and it's just a place to work in after the system is already
running, then why does it need a boot sector that is correct, eh?  If you
do not fix those initial errors, NDD will not lock up.  At least that is
how I have managed to avoid the problem with my clone (Award Bios, ST251-0,
2meg C:, 6meg D:, 12meg E:, 20meg F:).

	Of course, if NDD displays errors in the FAT or directory tree, let
it fix'em.  That's what it's s'posed to do!
