Unlocking a Bitlocker Drive with as USB Key - Possibilities

Hello Everybody,
we have a big Rollout where we have to move data from Windows 7 Enterprise Bitlocker encrypted Systems to new Windows 8.1 Systems. The data Transfer will be managed with USB <-> SATA Adapter which means the old encrypted Windows 7 drives
will be plugged to the new Windows 8.1 Clients. Since we have to do the Migration the way i just described please do not discuss alternative Migration methods ;-)
So if we connect the drives to the Windows 8.1 Clients they are of course locked and we have to unlock them to be able to copy the data. I already managed to get/modify/create two scripts.
One gives me a text file for every encrypted drive including the Password ID and the corresponding Recovery Password.
The file is a Text file and can be read by Notepad.
The other script gives me a so called Key Package for every drive.
https://technet.microsoft.com/en-us/library/dn383583.aspx#BKMK_AppendixC
The file is binary and crypted and have no file Extension.
So here are my questions:
The old systems have a System Drive and a Data Drive. When unlocking the Data Drive with the Windows 8.1 GUI Methods i have an Option called "load key from USB drive" - when i select this it automatically unlocks the Data Drive when a
USB drive is connected where is stored the previous generated Text Files.
When i now try to do the same for the encrypted System Drive, the option "load key from USB drive" is not appearing. Why is this? Is it a general Topic with System drives or is it a configuration issue?
Talking about the Key Package files generated by the script linked above:
I have no idea how to use this Key Package.
Maybe someone can help me out with this.
Thanks so far and Greetings
Paddy

Hi Paddy,
How you configured to lock the system drive with bitlocker?
You may take a look at the link below, see if it could help you here:

Disabling USB hard drives but allowing USB keys mounting, possible ?

Hi all,
I have a tricky request from one of my customers : they would like to block any external hard drives (firewire and USB) from mounting on the Desktop, BUT would like to allow USB keys only.
All the clients are unmanaged (local accounts, NOT bound to an Open Directory Master server) and are running OS X 10.4.8 (Intel).
I found the easy way to prevent any Firewire device to show up.
I also found how to disable all USB devices (except for keyboard/mouse) : renaming /System/Library/Extensions/IOUSBMassStorageClass.kext
Problem is, this method won't make any difference between a hard drive and a key, it will block it, period.
Is there any way to allow some (or all) USB keys only to mount ? My only guess would be to unload some extensions which are listed by the "kextstat" command.
That could only be possible if USB keys and USB hard drives don't use the same kind/brand of controller/bridge and therefore don't use the same kernel extension.
Does anyone have a clue on this ?
Many thanks.

Share usb hard drive with a usb hub

I have a USB Hub connect to the AEBS with a Dymo Label Writer and a WD USB drive connected. While I see the drive and the printers in the Airport Utility, I can't seem to connect to them from either WinXP Pro computer.
Any idea what is wrong that I can't see them

Hey guys, thank you all for your replies!
Given actual price of hardware, I went for a totally different solution...
I bough a used PC which I boosted with 4 GB of RAM... it's a intel dual core... and I plugged in a Terabyte SATA drive.
It's much less expensive than a mac mini.
Then I installed Ubuntu Server LTS and Samba for file sharing... FREE of course
All that to get a very great file server that acts in PDC (security=domain) mode so it's totally great
None of the NAS I reviewed gave me enough freedom for the file sharing management that I wanted, and the mac mini + leopard server solution where too expensive.
Once my little company grows, imma get a Xserve fo sho but for now, this setup is the best for me
once again, thank you for your replies

Macbook telling me that my external hard drive with a usb is pulling too much power and has been dialed what do I do

I have been using my Seagate Free Agent 500g external hard drive for years without even a hint of a glitch but this morning I trying plugging in the usb and got an error message that stated that the hard drive was pulling too much power and was being diabled. So now I cannot get the hard drive to connect period. What do I do - could it be a power cord issue?

Hi cactus flower,
If you are getting a message that a USB device such as your external hard drive is drawing too much power, there are a number of things you can do. I would suggest the steps in this article -
Apple Computers and Displays: Powering peripherals through USB
http://support.apple.com/kb/HT4049
Specifically this section -
Troubleshooting
If you have a peripheral (such as a hard drive, audio device, or camera) that is acting unexpectedly—such as not turning on or not being recognized by the computer—the peripheral may require more power than is available. If you have a USB peripheral or a chain of devices, such as a joystick plugged into a keyboard, which requires more than the available power try one of these options:
Use a USB hub that comes with a power adapter.
Check that the peripheral offers the ability to connect to more than one USB port at once.
Find out if the peripheral comes with a power adapter.
If you cannot confirm your device's use with a hub, connect the device directly to the Apple computer.
Thanks for using Apple Support Communities.
Best,

Why won't my new Airport Extreme recognize my USB Hard drive? My MacBook recognizes it. I already have had a great deal of trouble connecting my printer to print wirelessly, but finally resolved that. Now I want to add the external drive with a USB por

Why won't my new Airport Extreme recognize my USB external hard drive. I put a USB port on the base station, and the system recognizes my printer. When I click on disks - it lists my printer, and when I click on Printers it lists my printer. What do I need to do to get it to recognize the external drive? BTW, the MacBook recognizes it, no problem. I have erased it and reformatted it. I am running the new Lion OS. Any help is appreciated.

Yes, I saw a post on one of these threads about a powered USB hub so I ran over to Office Depot and picked one up. I was finally able to see the HD in the Airport Utility. Yay!

Encrypted USB Flash Drive with Lion OS X questions

Like many of us, we don't want our USB flash drives lost with our valuable data on them. So I've used the encryption function in Lion OS X in Disk Utility to make an encrypted flash drive. This has some limitations as I read but what I want to know is can I use this usb drive on a DIFFERENT computer that also has OS X Lion? I don't have another mac w/ lion to test it on.
This is important to me because I've got a laptop and God forbid, but if it was stolen or destroyed, will I be able to access my USB drive with important data on it by plugging it into another mac computer w/ lion?
Also, as a follow up question - I haven't yet made an encrypted DMG file (tho I plan to soon) and place that on a usb drive for multiple platform use, but how functional is this? Can you add and copy files within the DMG file? I thought a dmg file, once created, couldn't change in size, MB's, etc.
Basically, I'd like to use the most user friendly type of way of securing my files and data on USB flash drives. I have tried TrueCrypt and have it installed but I just don't prefer using it. I like the simplicity of the former approach, though it has it's limitations.

How about any computer instead?
Hardware based encryption is superior to software encryption which can be hacked or not available if your needs change.
This will work with any computer, and has a nice keychain so you can attach to something like your wrist or retractable key cable.
http://www.amazon.com/IronKey-Secure-Hardware-Encrypted-Flash-D20402A/dp/B000RXY V5U
There are also hardware based encypted external hard drives with their own keys and password keypads, also work with any computer if your needs are larger then a USB can handle.

Installing Windows 7 on MBP from USB key?

Hello all,
I've searched all around the internet, but I just can't seem to find a straight answer to this question:
Is it possible to install Windows 7 on an MBP with a USB key? Before you answer, read my process to see where I'm having trouble.
I want to install the Windows 7 beta on my MBP, but DVD media isn't available to me. I do, however, have a 4gb USB key. I've formatted the key with my XP install (through Parallels) to be bootable, and loaded the Windows 7 install on it. When I tried to use Boot Camp, the assistant asked me for a CD/DVD, so I figured that option is out.
My next attempt was to install rEFIx, which did show the USB key as a viable boot option, and even let me select the efi file to boot the Windows 7 installer. However, when I try to load it, I get a complaint:
Starting legacy loader
Using load options 'USB'
Error: Not Found returned from legacy loader
The firmware refused to boot from the selected volume. Note that external hard drives are not well-supported by Apple's firmware for legacy OS booting.
So now I am stuck. Can anyone offer me any advice regarding this matter? Any help at all would be greatly appreciated.

Windows normally cannot be installed nor boot from a USB or any external drive. This is a Windows problem. There are methods for installing and booting Windows from USB devices, but you will need to do some searching to find sites that detail the process. It's not likely you'll find much on Windows 7 because it's beta software, and not supported for installation on a Mac.

P55M GD45 experience; only 1.1 bios works, forum usb key boot didn't work, Win 7

My experience. Got board w/ 1.1 BIOS installed, installed Win 7 64-bit. Used LiveUpdate to flash BIOS to 1.5.
Then box froze at "Starting Windows" screen. However it would boot ok to Safe Mode, and also Safe Mode with Networking. It wouldn't boot to Knoppix, Ubuntu LiveCD, ... (In Windows 7, I spent hours trying stuff, did boot logging, turned off startup services, piles of stuff, but didn't seem to be getting anywhere...)
Tried using the Forum USB Key boot for BIOS flashing. Couldn't get it to boot, just got black blank screen with cursor. (Could this be because board doesn't support 98/ME?)
Finally figured out the M-Flash option, and tried 1.4, which gave same results as 1.5. Then went back to 1.1 and that got my Win 7 booting again ok. Then tried 1.2 and that gave same result as 1.4/1.5 (screen freezing), so went back to 1.1.
Later tested out HP USB key booter and that worked for me, though I didn't end up using it for anything, since I went with the M-Flash.
I was hoping that this new board would help me have better eSATA (hot-swappable/recognizable), than my previous setup but it's actually worse. With my old setup, I could plug in an eSATA drive, then Add Hardware, and the drive would be recognized by Win (XP). With this new setup, eSATA drives only get recognized if I have them connected and on before I boot up my box. Not good. Also, the BIOS has a tendency to prioritize the eSATA's before the regular SATA's in boot order, which seems weird.
Anyone else have any experiences like this? Any suggestions on moving towards a BIOS upgrade and more eSATA functionality (ideally without spending another 12 hours on it )
Thanks for reading and in advance for any suggestions!!

I have exactly the same problem and a reinstallation won't solve anything !
You will even not be able to finalize the installation !
Freeze in Windows Seven after several minutes even after having cleared CMOS + loads of optimal mode or fail safe mode...
Here is my computer:
-MSI P55M-GD45

-2600XT fanless gigabyte
-Corsair 520VX or HX I forgot it
No problem with the last bios 1.1.
!!!!! Totaly unstable with the last bios 1.5 !!!
I read your solution about reinstalling the OS after a bios update (that's the first
time that I read it and I owned something as 15 motherboards in the last 10 years...but
you have 20k post so I think that you know what you write...)
So I tried to REINSTALL after "upgrade" of the firmware 1.5 of the MSI P55M-GD45.
I did it with a USB KEY....not [email protected] with defaults values !
The only thing to do is downgrade the bios in 1.1 and now no problem @ 3.8 GHz !!!
WHY IS THIS BIOS SO unstable ?
What will MSI do ?
I have never had a so unstable motherboard after a bios upgrade !

[SOLVED] Many modules are not loaded in the Arch USB key installation.

Hello!
I installed Arch Linux on my USB key. I did it few months ago and it worked, I had portable arch.
Yesterday I decided to make a fresh installation. Unfortunately after booting it from my USB key
most of the modules were not loaded. Because of that I couldn't start the X server and connect to
the internet (ethernet card was not detected).
Even after loading the module which corresponds to my ethernet card manually (modprobe e1000e) it was not
displayed in the lsmod list.
I though "maybe I screwed something up during the installation?". To find out I used GParted to copy
my OS partition (perfectly working Arch Linux installed on the hard drive) to the USB key. Of course I changed the UUID of the USB partition.
After booting it I was suprised because the situation did not change - modules that are loaded on my main system for some
reason were not loaded on it's exact copy placed on the USB key.
I have no idea why my portable OS is acting like this.
Commands below were executed on another PC so don't look for the e1000e module.

How can I configure a VM to boot from USB key in Virtual PC of Windows 7?

Hi all,
I want to boot up with a USB key to install a new VM on Windows 7. I heared that Microsoft Virtual PC begins to support USB device on Windows 7. How can i configure it? I don't find any virtual USB device in VM settings on my Windows 7 box.
Thanks for any help.

Virtual PC does not support USB. Windows 7 XP Mode Virtual Machine supports the use of USB devices. Virtual PC and Windows 7 XP Mode VM are not the same thing!

Usb key for license

I'd like to buy adobe photoshop elements. I'd like to know if the license can be with a usb key instead of serial number. thanks

No. Adobe uses what in other circles is called a node-locked license, no floating licenses, no dongles. The activation can ever only be active on the two machines it is meant for and well, for such a cheap program as Elements going through more complicated licensing hoopla that keeps IT admins busy at big facilities seems just an odd idea.

How to create a virtual machine from a windows 8 installed in a usb drive with bitlocker on

BAsically I created the vm with dissk2vhd and then mounting it on oracle virtual box but the bit locker is not letting the machine start. How can I bypass this
Many thanks
Fab

I'm not sure you can, bitlocker ties your installation to the hardware.
"To P2V a BitLocker drive, please suspend the protection"

Bitlocker will not unlock fixed data drive automatically

I have two fixed drives on my new system:
A 500 GB Samsung SSD with the OS and programs; and
A 250 GB Samsung SSD with my Dropbox and other data files.
The OS drive is encrypted with Bitlocker using Hardware Encryption and TPM+PIN+StartupKey.
The Data drive is encrypted with Bitlocker using Hardware Encryption and its current protectors are listed as:
Key Protectors:
External Key
Numerical Password
Password
External Key (Required for automatic unlock)
Automatic-Unlock is listed as "Enabled."
However, when I start Windows the drive does not automatically unlock. This results in error messages from several programs that must be manually overridden. Then, I have to manually enter a password or point Bitlocker to the USB drive containing
the recovery key.
I have tried disabling BDE, adding the password, re-enabling, etc. Nothing works! This seems like a textbook setup of bitlocker, but it simply refuses to unlock automatically, even though the OS drive is encrypted and the correct protectors are
present.
Am I doing something wrong? Or does Auto-Unlock just not work?

Auto unlock does work here dor a c: and d: setup on about 30 devices with 8.1.
The protectors for d: list as
Numerical Password:
ID: {1FE7C7AF-D6A5-4DE1...
Password:
XXXXX-XXXXX-...
External Key:
ID: {96463736-93ED-4107...
External Key File Name:
96463736-93ED-4107-AA...
Automatic unlock enabled.
Note: it does not show your "(Required for automatic unlock)".

How to re-lock a drive with bitlocker

I am using windows 7 bitlocker to encrypt a secondary hard drive. So I unlock the drive with the password successfully. Now how do I relock the drive? The only way I can see is to restart the machine. What bothers me is that even if you log off, and log in as another user the drive is still unlocked! Isnt there a menu item or option to re-lock it?-mi

I made a .cmd-file to re-lock the drives:
From a cmd-prompt, type the following:
C:\Windows\system32>copy con lockdrive.cmd
manage-bde -lock l:
manage-bde -lock k:
^Z [press CTRL-Z]
1 file(s) copied.
Replace l: and/or k: to the corresponding drive letter on your computer.
Make a shortcut to the lockdrive.cmd-file, and check the "run as administrator" check box.

That works great, thank you. Some points to clarify for those of us not so advanced in computing. Just to point out I am running Windows 7 Ultimate with UAC turned off. I'm
not sure if this will work in other versions or with UAC on, I think so but perhaps someone will confirm this.
To turn off UAC, go to control panel, select 'User Accounts' then your account name, 'Change user account control settings' and select 'Never notify' and reboot. Next navigate
to 'Control panel / Folder options', click the 'View' tab and move the radio button to 'Show hidden files, folders and drives', then uncheck the 'Hide extensions for known file types' box, Apply, OK and close Control panel.
1. It is easier to go to your windows folder, find the System32 folder, put your mouse cursor on it, hold the shift key, right click and select 'Open command prompt here'. That
way when the DOS window opens you only need to type "copy con lockdrive.cmd" (without the quotes) and press Enter.
2. Type "manage-bde -lock #:" again without the quotes and replace the "#" with the letter of your bitlocker drive as Inge stated. If you have another drive to lock then repeat
this line with your other drive letter and press Enter.
3. Hold 'Ctrl' on your keyboard and press the 'Z' key once, '^Z' will be displayed, press Enter on your keyboard and '1 file(s) copied' will be displayed.
4. Type "exit" (no quotes) to close the DOS window.
5. Navigate into this folder 'C:\Windows\System32' and look for the file 'lockdrive.cmd', right click it and select 'create shortcut' a new file called 'lockdrive.cmd shortcut'
will appear below it. Right click the shortcut file and select 'Cut'.
6. Navigate to 'C:\Users\*YOUR USERNAME*\AppData\Roaming\Microsoft\Windows\Start Menu\Programs' right click in a blank area of the window where your Accessories and Administrive
Tools are (being sure not to highlight one of the other files) and select 'Paste'.
7. Right click the ''lockdrive.cmd shortcut' and select 'Rename' and just call it 'Lockdrive.cmd' and press Enter, then close all windows.
8. Click 'Start', select 'All Programs' and look for your 'lockdrive.cmd' file. Put your mouse on it, left click and hold the button down. Drag it down to the 'Back' selection which
was 'All Programs' and wait for the first Start Menu to appear, move your mouse up to a blank area and release the button. If done correctly you should now have 'lockfile.cmd' on your main Start menu. Click it to lock your drive.
9. Navigate to 'Control panel / Folder options' and on the 'General' tab select 'Restore Defaults' and Apply. Select the 'View' tab and select 'Restore Defaults' and Apply.
Click 'OK' and you’re done.
Thanks to Inge for this short and perfect work-around.
