Perfectdisk 8 Boot time defragmentation issues


whenever attempting to schedule a boot time defragmentation for the MFT and Pagefile I get  failed to open"/"driver conflict" error messages upon boot up

According to the website support, its due to other 3rd party softwares that are locking the harddrive preventing Perfectdisk from gaining exclusive access on startup

The only application from the list that I have installed is Zone Alarm, for which I disabled the srescan according to the instruction in the link. Also the engine version of my installed Zone Alarm version is higher than the required version in the guide ( The problem still persisted though

Aside from zone alarm I don't have any other application from the list installed. I used to have TGTSoft sytle but I switched to windowblinds 5.0, hence its no longer installed in the system. I tried unistalling windoblind to see if it is the conflicting with Perfectdisk since its similar to stylexp, still with no effects

Has anyone had similar problem?

based on the link and some checking this should only be an issue with regards to v 7 of perfect disk. What kind of hard drive are you trying to defrag? Is it your boot drive and parttion? anything else special about it, like requiring third party RAID driver software?

I have two seprate SATA drives, one is the boot drive 80GB (Window XP professional in my case) and the second for my data 160GB (my pictures, mp3z, setup files, drivers...etc). They are installed and configured as follows

Each parititioned into one single primary partition
The boot drive is plugged as SATA 0 while the data drive is plugged to SATA 1

The boot drive is the disk I am attempting to boot defrag. Online defragmentation for all files runs fine, however for defragmenting pagefiles and MFT files, a boot time defragmentation is required since these files are normally locked by the operating system and can only be defragmented in a reboot enviroment, pretty much like partitioning a harddrive on which the operating system is running.

The buttomline is that an exlusive access to the harddrive is required for defragmenting the system files, which my Perfectdisk is unable to handle due to possible interference from 3rd party softwares as suggested by the support link which perhaps apply to my current version as well

I managed to resolve the problem

After playing around with the settings in PD, I ran into the following settings

Help >> About >> Support Info button

Clicking this button brought up a support info dialog that apparently contains troubleshooting information, after scrolling down to the button I found this interesting piece of information under the 3rd party software circled in the picture below

According to the support link previously discussed above, that sptd service is employed by Daemon tools and alcohol 120, since I never installed alcohol 120 and Daemon tools was removed from my system long time ago this case shouldn't have been applicable, I suppose that sptd driver/service was left behind somehow even though removing Daemon tool should in theory have removed it, which was the case for Zone alarm and style xp

Anyway so I went to the registry


And changed the start value from 0 to 3 (where 3 as far as I know indicate manual restart)

And the problem was solved
