[comp.os.msdos.misc] Trouble with IBM Model 70. Help!!

I am having very annoying problems with my IBM Model 70.  Perhaps
someone can help me in tracking them down.  Some of the most recent ones
are the following:

1.  I have tried 3 of the standard high quality backup programs and none of
them worked perfectly.  So I decided to try the DOS backup.com.  It seems
to have worked, except for one strange thing. Namely as I was backing up
my ARBORTXT directory (with the /s parameter in order to include the
subdirectories), the name of the file currently being backed up appeared on
the screen, of course, but every time I inserted a new disk when prompted
to do so, the name ARBORTXT would be misspelled each time until the
program came to a new subdirectory.  So for example such things as 
A*BORTXT, A(BORTXT, etc appeared. It was always the first R that was
replaced by something else, sometimes another letter, once an up-arrow
(ascii 18h), another time a carriage return,  and so on.  These errors were
also recorded in the log file backup.log.  I haven't tried to restore them...
BTW I did this from within Windows 3.0.  On another try from the DOS
prompt (on another drive), this did not occur.

2.  After backing up, I tried using PCTools compress.  It started to
compress, then halted and said that there was not enough disk space.  When
I exited, I was told that I had some lost clusters. I used chkdsk \f , turned
them into a file, and deleted them.  Then I tried running compress again,
with the same result:  I lost a few more clusters.  Needless to say, I didn't
try again.


3. It might be worthwhile to add that a couple of weeks ago, there was an
error message saying that the hard disk controller was no good, when I
booted up.  The diagnostic routine on the reference disk said the same
thing, and that the floppy disk and parallel port were also kaput.  I took the
machine back to the dealer.  They checked it out, first thought that the hard
disk itself was at fault, then installed the hard disk in another Model 70,
found that it worked there, reinstalled it in my Model 70, and it worked
there too.  So nothing more was done at that point and I started using it
again.
  I used the diagnostic routine again after problems 1, and 2. above, 
and everything checked out except for an error message "401" regarding the 
parallel port, saying that I should have the unit serviced;  I have been 
getting this error message for some time now, even before my present spate 
of problems, and certainly nothing strange has been happening when I print 
documents (my printer is of course attached to the parallel port).  When the
dealer checked the machine, this error message re the parallel port did not
appear.
