File Share Encryption

I have read much discussion about recovering hard drives that have crashed. However, I have read little regarding the root cause of crashes as most seem to imply physical failure. I have just crashed/ unbootable two hard dirves by simply attempting to install drivers for a Logitech camera. Repeatable. Perhaps something Symantec can simulate in their lab and correct. Would also like my disks recovered. How often are other crashed caused by simple user acts of driver installataion vs. physical failure? Thanks

I this issue the same as the problem described here:

I can't tell when yo usay crashed/unbootable whether that means that it gets stuck on preboot authentication like described in that above post or if you get a blinking cursor or what?

First time i have heard of a webcam corrupting the MBR if that the case...

When I attempt to boot using Win xp it blue screens immediately ( I am on a trip out of state now so I can't tell you the exact Blue screen message.....which did exist and indicated a disk failure). Will update this note next Friday when I return. When I removed the disk and attempted to access it from another machine it  indicates that the drive is unformatted. Again, this occurred on multiple drives doing nothing tricky or fancy.

Thanks

Are these solid state drives? If so, can you please list the model numbers of the drives in question for me?
