I should also report that I just spent a day fixing my computer after I
"successfully" merged the unallocated free space to the c: drive on PM6.
Turns out that I could no longer open a few of my more important programs
including Norton SWS. Since the Norton uninstall would not complete by
itself, as well, I had to manually purge my computer to get a success
reinstall. I will think twice next time. Are there reliable alteratives to
PM that I should consider or is repartitioning just fraught with potholes?
Repartitioning with PM usually works fine. I've done it
tons of times.
If you successfully merged the partitions and had only
certain programs misbehaving afterwards, but that you are
sure worked prior to this operation, it seems most likely
your system has memory errors and has corrupted files while
rearranging the data. There might be other possibilities
that don't occur to me at the moment but I would run
memtest86 for several hours... actually would've done so
before redoing the system since there might still be memory
error induced (new) file corruption.
FWIW, I don't use PM6 anymore but v8. Heres's how I'd have
done the operation you did:
1) IF the system is using a drive overlay (software to
extend HDD capacity support for the motherboard), be sure
you boot from the HDD, not a floppy so the overlay loads.
2) Once PM is loaded, there's no point in trying to resize
empty partitions, just delete it, that logical extra
partition and the extended partition it's in, leaving only
the Primary C partititon alone for this step.
3) Primary C partition is the only one virtually existing
on the PM screen and you choose to resize it larger. PM
does things sequentially so if you still wanted the other
partition, the NEXT step in the sequence you choose is to
create the extended partition in the remaining space
(presuming you wanted it to fill entire remaining space),
and then IF you want any logical parititons in it, create
those.... I see no real reason NOT to create the logical
partitions, even if you have no immediate need they might as
well be accessible space already available for a future use.
4) You click apply and PM makes the remaining changes. If
it can't do ALL of them at that time, you may need reboot
to PM, and complete the remaining steps.
5) Of course, if you had memory errors, your method
might've worked fine otherwise and the steps I just
described might not work any better.
