BitLocker Drive Encryption - Windows 7 Drive - Turn On or Off with no TPM

Thanks Brink, youve been a great help. Any chance you could help me with a thread I created in the system security section about bitlocker and dual boot.

Just as a heads up,
For those who just want to decrypt a drive such as USB, just authenticate and mount the drive, then open the BitLocker control panel. In the control panel, to the right of the drive icon you will see the option to decrypt the drive.

Hi

Tried to turn on bitlocker on drive C, no TPM device, just USB stick.
Got an eror that the startup key was not found on the USB device, tried another device, worked.

I have six 512Mb usb devices to use with bitlocker, but none of them work.
they are fat32, same as my 4 gb that works. the .bek file is written on all of them but doesn't work.

any sugestions ?

Hi,

That didn't help.

diskpart -> select disk 1 -> clean .. formated as fat32.. still the same thing.

Strange. Is the startup key save to the root of the USB flash drive and not in a folder?

Did you use the Manage BitLocker option to "Duplicate the startup key"?

How do the USB keys work if formated with NTFS?

yes, the .bek file is saved to the root.

same issue with ntfs.

sticks can be made bootable, tried that just to check.
