Defragging Vista Home Premium - Diskeeper v PerfectDisk

Defrag Diskeeper 2008 Pro versus PerfectDisk 2008 Pro

Having used Diskeeper 2008 Pro I noted a marginal preference expressed on
this NG for PerfectDisk 2008 Pro, so I uninstalled Diskeeper and installed
PerfectDisk on 30 day trial.

In use I felt that the PD approach of getting the most used files to the
edge of the disk to reduce the amount of file movement was a good idea and
there seemed to be some slight improvement in speed. However when I set a
boot time defrag, a low level error message came up something like "Unable
to gain exclusive access to drive C", chkdsk was not run, and no boot time
defrag took place as far as I could tell.

After a couple of days I uninstalled PerfectDisk and reinstalled Diskeeper
whose boot time defrag still worked perfectly, but booting was slow and
accompanied by an error message something like PDBoot.exe not found -
skipping autocheck.

So I was generally impressed with PerfectDisk, but disappointed that it
couldn't perform a boot time defrag and that it failed to remove all traces
of itself when uninstalled.

But that leaves me with the nagging thought - could it have been that it was
Diskeeper that failed to uninstall cleanly, making PerfectDisk "Unable to
gain exclusive access to drive C"? Or is it a Vista problem?

Has anyone here mastered boot time defragging with PerfectDisk 2008 Pro?

I had the same thing happen to me. Look in registry for pdboot.exe and
delete the key(s)

Utilities are supposed to work with the OS, not the other way around. I
stick with Diskeeper and run it once weekly..

Hi Doug, I have been using perfect disk for about two years now and have
only had problems with boot defrag on a raid array that I never got
sorted.
Otherwise I am perfectly happy with this program.

I agree that your problems are probably caused by a bad uninstall and
hope that you get them sorted out quickly

I had that problem a while back, and it was resolved by installing a later
build of Perfect Disk 2008.

(From Support on Raxco's Perfect disk site: "Microsoft made a change in
Vista SP1 that prevents PerfectDisk's boot time defrag from running. This is
fixed by updating to PerfectDisk 2008 Build 52.")

It works fine now.

I had that problem and Diskkeeper was never installed. I also had the
problem before SP1 was installed, but it is always best to get the latest
copy. Since he has the latest (at least I would assume the trial download
would be the latest) version, it probably isn't that unless they broke it
with a later version.
I personally didn't find any improvement using either. I ocassionally run
defrag using the command prompt.

Mike H, pooch, John E and John B.
Helped by your combined support to look for the right sort of thing on the
raxco site, I
eventually I found this:
http://www.raxco.com/support/kb_deta...rod=1&ver=2008
which resolved the problem so that PerfectDisk 2008 Pro now does boot time
defrag.
Very many thanks - Doug

After trying out both, I decided to stick with Diskeeper. Havent had any problems with its boot defrag.

Rajan

Here is how to get rid of Diskeeper boot error messege PDBoot.exe not
found.

Start - run - type " regedit " without the quotes , click ok.
Go to
HKEY-LOCAL-MACHINE/System/CurrentControlSet/Control/Session Manager.
Left click on Session Manager.
Under " Name " you will see " BootExecute ".
Right click on this and in the popup box click " modify ".
In the popup box " Edit Multi-String " delete all entries that say "
PDBoot.exe ".
This should leave you with the default Windows entry " autocheck
autochk * " This is all you need. If there are other values then you
have other programs
loaded that also use this. My computer has "OOdefrag" installed so I
have "OODBS " after the name.
Make sure you do not leave any empty spaces before the entry "autocheck
autochk *" or you will get an error . If you do just click OK and
regedit will fix
it for you.
Now reboot and you should be rid of the annoying popup error at boot.
