Toshiba Problems with HDD Protection Vista x64 Business

This has me stumped. Got a new Toshiba u205-s3057 with Vista Home Premium. Did a clean install of Vista Business x64. Worked fine. Downloaded the Toshiba software to update the OS. Installed it all per instructions from Toshiba - made sure all were x64 drivers. When I reboot, it won't run. Get an error about a bad / corrupt driver at windows\system32\drivers\thpdrv.sys. A search told me it was the Toshiba HDD Protection program I installed. Can't boot into Vista at all. When I try to repair it with my install cd, get the same error. Here's my question:

Is there any way I can boot into my computer to uninstall that software that is causing the problem. Right now, I can't get in at all via the HDD...even trying safe mode and other modes.

I'm going to try the ultimate boot cd 4 windows and see if I can do anything with that, but that's 32-bit and my install is x64, so I'm not holding out any hope.

Any help would be greatly appreciated.

Hi,

I am going through the same problem right now. I have a Toshiba M400-S4034. Toshiba does not support x64; vista or otherwise, and according to their "friendly staff" they are not planning to.

While some of the drivers are supported, thpdrv.sys is not one of them. When I tried installing it, my computer spent about 10 minutes trying to shutdown and then gave me the same error you have above.

The only difference being that I was given a prompt to insert my vista disc to repair the installation, but I chose Last Known Good Configuration which worked fine and quickly. If that option is not available I would try booting from your vista install disc, and choose repair, which should be at the bottom left of the first window you see.

Good Luck.

Thanks for the suggestion. I tried that unsuccessfully...also had a few devices in device manager with ! (incorrect or missing drivers). After a couple days of trying to make it work without any support from Toshiba, I finally gave up on the x64 version of Vista and installed the regular 32-bit version. Too bad, the Toshiba machines really scream, would be nice to see it on x64 platform.
