Bit Locker Encryption

1. Once the Bit Locker enabled on a drive, how do we confirm on data which is stored in that drive are encrypted?
2. The data size stored on encrypted drive vs non-encrypted drive will be same or different?

Bit locker encryption requests key unless I suspend and resume the encryption

I am rolling out new computers with Windows 7 Enterprise OS on them. I am installing bit locker encryption on them. For some reason with this group of computers, and I recently rolled out a different batch of computers without this problem,
after encrypting, I must suspend and resume bit locker or upon restart of shutdown and start the user is prompted for the bit locker encryption key.

Hi,
Could you please tell some more details about the issue? What do you want to achieve here? To enable bitlocker without the prompt of the startup key? If it is , then please take a check if we have Require
additional authentication at startup policy enabled.
Besides, could you please have a share for how do you enable bitlocker?
And here is a guide for bitlocker in Windows 7, just for reference:

Windows 8: Bit Locker encrypted drive "Access Denied" external drive

I rebuilt my computer and installed win 8.1 pro. Now my external drive comes up as an empty drive with "Access denied". Here is the kicker: I had turned off bitlocker on the external drive long ago as it interfered with automated backups.
Running the commands suggested here:
https://social.technet.microsoft.com/Forums/windows/en-US/738c1760-c96d-430f-9ae6-1f28f5c60998/windows-8-bit-locker-encrypted-drive-not-found-or-access-denied?forum=w8itprosecurity it shows the bitlocker but as unlocked. Drive still shows empty.
Any suggestions?
Thanks,
Markus

Ahh, turns out to be permission issue not bitlocker (or maybe bitlocker caused it to lose permissions, don't know).
Opened MyPc, right click on drive ->properties->security->advanced and selected apply to all.

Windows 8: Bit Locker encrypted drive "Not Found" or "Access Denied"

I just upgraded my Windows 7 Ultimate to Windows 8 Pro. C drive is not Bit locker protected, but D drive is. When I go to Computer and double click on D drive, it tells me one of two errors: 1) Application Not Found (more common), or 2) Access is Denied
(less common).
I thought maybe Bit locker wasn't working, but I plugged in my USB stick that is encrypted and had no issues; it asked for the password and opened the folder.
One thing I did earlier was to setup a new local account, give it administrator password, then delete the other account that I had originally used in Win7 (and in installing Win8). Maybe this caused some sort of security problem.
Please help.
Thanks.

I have been using Bitlocker since it was available with Vista Ultimate. I have had the same password to unlock my drive for 5 years. I NEVER keep my recovery key this drive. but just last month i copied all my data to another drive formatted
it to freshen it up and copied it back over. For some reason i kept the recovery key TXT file.... when i tried your method here due to the same exact problem listed the command prompt would not allow me to enter a password in CMD or powershell. Since
i had the recovery key .. THANK GOODNESS it unlocked perfectly and i was able to retrieve my 6 years of Data. So yes, this works and works well. thank You!

Data Recovery from Partitioned and formatted Bit Locker Encrypted Drive

Recently because of some issues in windows 7 installation from windows 8 installed OS. it was giving as the disc is dynamic windows can not be installed on it. so at last after struggling hard no other solution i partitioned and formatted my whole
drive so all data gone included the drive which was encrypted by bit lockers.
For recovery i used many software such as ontrack easy recover, get data back, recovery my files professional edition but still i couldnt able to recover my data from that drive. then i found some suggestion Using CMD to decrypt my data first
http://technet.microsoft.com/en-us/library/ee523219(WS.10).aspx
where it shows it successfully decrypt my data at that moment my drives were in RAW format excluding on which windows is installed and then in CMD i check Chdsk which also shows no problem found. but now problem is still i coudnt able to recover
my data then i format the drive D and again tried to recover data using above software after decryption still no result.
Now i need assistance how i can recover my encrypted drive as it was partitioned and also formatted but decrypted also as i have its recovery key too. thanks

Bit locker unable to turn on

Hi,
I am trying to turn on Bit locker for removal Disk, could not succeed. System says that, required services not enabled. I remember I changed the registry setting to disable to bit locker encryption. I do not re collect what I have changed. Could you
please let me know what setting value is to be set for enabling the Bit locker encryption.
Thanks

Hi,
As narcoticoo mentioned, do we have TPM chip on the computer? Please take a look into Device Management, if the TPM driver is installed then it will show up in the Device Manager, under Security Devices as mentioned.
Please also take a look at the below article regarding how to turn on/off bitlocker without TPM:

Bit Locker Drive Encryption of Windows Vista

Have just downloaded the Bios Upgrade version 2.2 (QG40 BIOS_W220.exe), but I inadvertently omitted to turn the 'Bit Locker Drive Encryption of Windows Vista' off first, as Toshiba had advised.
Is there any corrections I can make to rectify this omission and ensure the G40 and the software operate correctly?

Thanks for your prompt reply Jeka-Nn. But I have several further questions before going too far with the suggestions as I am not familiar with software modifications.
1. What am I actually trying to do overall by downloading and using the suggested application.? Can you give me some overall picture of what I am trying to do?
2. Does this fix the problem without me having to make choices--is it self sufficient/self-installing?
3. Will it return the system to its correct operational settings before I downloaded the Bios upgrade?
4. I have downloaded the application suggested, but when I try to open the file it sends up a message that reads:
Error; this installer does not contain any compressed files. To create a self extracting installation package (with embedded files) run:
"TrueCrypt Setup.exe" /p
When I press OK, it simply reverts to the downloaded list which has the TrueCrypt v7.0 included, but nothing else happens.
What do I need to do to fully install the application?
5. Are there any other steps /inclusions that I need to make to fully correct my 'stupidity'?
Sorry about all these questions but you can see I am a raw beginner at this work.
With thanks, rons

Bit locker security issues (easy to crack) disk encryption?

Bit locker security issues (easy to crack) disk encryption?
Problem 1: When the PC run I think its too easy to get malicious users (with usb pendrive) or spyware to get the encryption key (fast and easy)
youtube.com/watch?v=0npTlOq6q_0
Problem2:not resistant with bruteforce attacks
youtube.com/watch?v=zvaJxnvbGic
Problem 3: not resistant with boot hacking
Im using DriveCrypt plus pack and searched security issues in bit locker.The bit locker allow you the bruteforce/dic attack easy.I think It would be much safer 1. (I think the keys stored somewhere that is easily read) 2. Do not just be enough password
need a password+file combination to decrypt the disk. DriveCrypt plus pack use a file+password combination if you know the password but you wont have the file you can not decrypt the disk (protect with bruteforce attack).On system boot protected bruteforce
attak you can crash the (boot).If the boot system crash you can not decrypt the disk just the password you need the file+password combination plus to decrypt it. I am not a programmer but I see the BitLocker ( easy security catches to crack the disk encryption).Im
tested DriveCrypt and I can not get the key that easy (Problem 1). I have not tested it in greater depth just trying to (catches to crack software encryption).

Where is your question, sir?
If the question were "is it easy to crack", the answer is "no". Your videos make use of several assumptions and ingredients and permissions that a normal attacker does not have.
"Problem 3" is not clear, please describe what scenario you are talking about.

Bit locker Mutliple Drives Mutliple OS's

I have a laptop with two hard drive in it. The primary has Windows 7 Enterprise and is a member of the corporate domain. The secondary has Server 2008 R2 and is a member of the lab domain. There is no trust or association between domain.
The laptop does the Windows multi-boot off the primary drive. I want to enable bit locker to secure the drives.
If the two windows environments were exclusively separate, setting up bit locker on each drive independently would be pretty straight forward, but when I'm in one OS, I will frequently need to get files and data from the other drive (and no, making each
drive big enough to hold all it's own data is not an option, plus the synchronization headache). Both drives will need to be bit locked to their respective OS, but the other drive will need to be accessible.
And not to make things too easy, the secondary drive, which i put in an optical drive bay carrier, routinely gets pulled (not while the system is running, of course) out and popped into a USB case to be used as a library transfer drive.
So....
the Windows 7 drive needs to be natively bit locked. and be accessible when running Windows 2008 from the second drive.
the Windows 2008 R2 drive needs to be natively bit locked, and be accessible when running Windows 7 from the first drive, and be accessible when run as a stand-alone USB drive on another system.
I would appreciate any wisdom you can share to make this all work. And please presume that i know next to nothing about installing and running bit locker, because that's pretty much true.
Let me know if you need more information about my configuration.
Thanks

Hi,
"and be accessible when run as a stand-alone USB drive on another system."
Firstly, if you enable bitlocker for one drive, it will be encrypted always until you decrypt it. Thus after you insert it to any system, it need to enter the credential to access it.
And then, if you want to access one drive in another computer, you need to get the shared permission. After you' re granted the sufficient permission, you could access it no matter if it's encrypted. Of course, another computer must be started.

Hi，
If you lost recovery key and are unable to access the disk at this moment, then I'm sorry but I have to say that you're lost. If the data in that encrypted drive is very important for you, then you might need a data recovery center to help you.

Bit locker and one drive

HI.
I would like to find out what would happen if I were to user the bit-locker to encrypt my drive and all it files but at the same time ,the files that's in my one-drive are synced with 365 and shared among many other users.
When they open their one drive will the file I updated be encrypted forcing them to enter a decryption password as well.
thanks

no
The file encryption is part of the filesystem. When the file is transferred it is sent unencrypted.
