Thanks very much for the information. I'll pass that on to my daughter and hopefully it will help to resolve the issue. Thanks again!Does her friend see a lock icon in my computer on the hard drive when connected? If yes then your daughter might have accidently enabled Bitlocker on the hard drive. The default password would be her Microsoft account password. What she could do is connect the hard drive again to her T200 and right click and disable encryption and that should do it
Do you want to encrypt the data on your disk?
There's a performance hit, but will it make a difference?
Personally, I'd do it, but I'm a bit more security conscious in that regard. Normal people? Eh.
I thought it was enabled by default though. (I could be wrong)
Bitlocker is nothing but a ballache! avoid!
