Hi, To troubleshoot the issue, I suggest you restart the machine in Safe Mode and plug the external encrypted drive on the machine, and then type the password key again. Does the window freeze up now? If not, please restart the machine in Normal Mode and perform a Clean Boot to check the result. Otherwise, I suggest you plug the drive on another Windows 7 machine and unlock it. Does the issue persist? If not, please run a Check Disk and move the drive back to the original machine.

Thank you so much for your assistance, yet I tried to access and decrypt the drive while in SafeBoot and goes unresponsive just as on normal boot. I have no other machine running on Windows 7, just Ubuntu and XP. Any other suggestions? i appreciate your help thank you once again...please give me any other alternative thanks

I know I am posting to an old thread. But since I spent several days on this issue and finally got a proper solution, thought of posting it here. I faced the same issue with my 1 TB HDD. Problem was due to Disk Queuing and 100% activity time in disk access. You can verify this with Task Manager -> Performance->Disk->Storage tab. So my ordinary Gigabyte motherboard ( could not handle the BitLocker IO. I ran the pc for few days but it did not unlock for me. So I took the HDD to another high end server in another facility and it just worked:) Decrypted the entire data in an hour!!. So check if you are facing disk queuing IO issue. If so, you need to connect this to a better hardware.
