guys, what does it mean when my internal sata drive (non OS) doesn't show up in Bitlocker page in Control panel? I don't have the option either when I right-click on the drive on the explorer...

thanks

Hello Tierix, and welcome to Seven Forums.

Sorry for the late reply.

Could you post a screenshot of your Disk Management (diskmgmt.msc) window showing all of your drive's layout? This may be able to help ID what the problem may be.

If this is a dynamic disk, then that would be one reason.

HI

Thanks a lot for your reply. Screenshot attached. Yes it is a Dynamic disk (DRIVE F). Why Dynamic disks can't be bitlocked?
Also, please, how do I change it to whatever it should be?

thanks

Tierix,

Yes, it will need to be a Basic disk instead of a Dynamic disk to be able to use BitLocker on it.

You could use OPTION FOUR in the tutorial below to convert F: (Disk 0 ) back to a Basic disk without losing the data on it. Be sure to backup the data on F: to another location before continuing just to be extra safe though.

Convert a Dynamic Disk to a Basic Disk

Hope this helps.

ok i'll try that. I'll have to do it in a few days though, I'm in the process of backing up the whole drive to an online service and I feel like I defo should do it before trying this!

thanks again

The problem I have is that I've got a 2TB Fantom external drive that when I purchased it I was running Windows 7 Ultimate so I used Bit Locker and encrypted the drive. No big deal I thought, I've got the key on a USB stick and all - PC died and the new one came with Windows 7 Professional - eeks! I can still access my files but have to type in a password every time I power on the external drive as it's primary use is for backup's. Is there anyway possible to remove the encryption from this external HDD? I would suspect if I backup the data to a different drive and delete the partition, recreate a new one and format it the Bit Locker encryption would be gone then? Lot a work as there is 1.5TB of data on this drive There has to be an easier way to simply decrypt a drive??

Found the solution here on Sevenforums:

Use this command in elevated command prompt
manage-bde
this will pull up drive encryption options via command prompt
to decrypt a drive just type in
manage-bde -off C:
replacing C: with whatever your decrypted drive is.
command prompt reports back Decryption is now in progress
It's a 2TB drive and had been reporting Bit Locker Status: Decrypting for the last 30 minutes now so it might take a while, my only concern will be are my files going to still be there and in tact?

Great news luvwknd, and welcome to Seven Forums.

Yes, your files should be fine afterwards since it's only decrypting the hard drive.

Is the decryption process going to take longer since there is 1.5TB of data on a 2TB HD as compared to a blank encrypted 2TB HD?

Reason I am asking is because I started the decryption process yesterday about this same time and the HD is still reporting Bit Locker Status: Decrypting and when I click on the drive itself it reports 5.99GB free of 1.81TB and I know for a fact that there was plenty of more available space on that drive than 5.99GB.

Any ideas?

TIA
