Uninstalling the Tool
Uninstalling the Tool
In the service's properties (double-click), you can change its start-up type, or you can start the service manually, if necessary.
The program is registered within Windows as a system service and executes every time the system starts up - even before a user logs on. It quits after several seconds and doesn't take up system resources any more.
If you wish to uninstall the service from your system, simply enter the command thgsvcdebug /u at the command prompt (/u for uninstall).
Previous Trouble with the WD Raptor
About a year ago, we already had a run-in with Western Digital's Raptor WD 1500. In our article Four 975X Motherboards For Core 2 Duo, we mentioned a problem with the ASUS P5W DH, the source of which we were unable to identify at the time. After several reboots, the board was no longer able to recognize the hard drives. Thereupon we contacted ASUS and asked for help, but the company was itself puzzled. Later, we found out that other publications in Europe had encountered similar problems. ASUS insisted that their motherboard is not at fault for this shortcoming. We were even sent a revision of the drive's firmware that was never officially distributed by the manufacturer. However, this revision did not change anything. The reason: It was the same version already present on the drive's EEPROM (20.07P20).
The bone of contention: Western Digital's fast 10,000-rpm Raptor drives.

I really appreciate the trouble you went to over this problem.
I have 4 x Raptor 150GB and 2 x EVGA 8800GTS working fine under XP. But under Vista 32 I get the sysmptoms you describe. I wondered if you discovered any of the following
1. Is the problem only when Vista is installed on a Raptor 150GB drive, or will it occur when any Raptor 150GB drive is present in the system even if only used for data storage?
2. Does the problem still occur with NCQ disabled?
3. Does the problem still occur on Vista 64 bit?
4. Does the fix work in all cases? It doesn't seem to install on my system. I get no response message after I type the command to start the service.
Thanks, Mike
I believe I have the debug system service installed, but it won't start automatically or manually.
When I try to start THGDEBEGSVC it get the error message "Unable to start - access denied"
Any idea how I can get round this?
Thanks,
Mike
Don't you mean Intel and AMD platforms?
After exaustive troubleshooting and Headaches I found 2 issues to be the culprit and niether have to do with bad hardware nor issues with Vista.
The first has to do with BIOS settings. In nVidia's BIOS there's a selection under H/D's called memory Blocking. It's supposed to help up transfer rates but really causes problems with the Raptor H/D's.
I had to disable this feture to get the Raptors to work at all.
The second was so simple it was my last effort before RMA and it worked.
The SATA Cables that come with the M/B don't support the faster Data transfer rates and cause a Bottleneck within the Cable itself.
Replacing the Cable with the one that came with the Raptor solved the issues completely.
I know it sounds odd but after doing this my system has run flawlessly for the last 3 Months.
Like I said before it was the last thing I did before RMA and I've been through all the stuff you did as well as a few more tricks I tried and nothing would work.
I even did the SATA Plug swap and as you stated, it works for a little while but then the problem comes back within a few Days to Weeks.
It's not the manufacturers fault, they supply SATA Cables that if used with a regular 7200rpm H/D work great. The problem is that the Raptor H/D's run data rates way faster and the Cables that come with M/B's can't handle it.
Best Regards Eirik.
