Preferred Solution: the bitlocker metadata for encrypted drive is not valid, you can attempt to repair the drive to restore access

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)


I enabled bitlocker by editing the group policy. At tha time, I encrypted my internal and external hard drive. The internal drive saved the key to my usb drive and by default, the external drive save it in my Documents folder. I also selected the auto-unlock option to prevent myself from having to key my password each time I used the drive. Due to performance issues after upgrading from Vista, I decided to reinstall Windows 7. I copied all of my data over to the external drive from the Documents folder, right clicked th external drive from the Computer folder and assumed by removing the password, which is allowed since the auto-unlock setting was enabled (not the best idea for those who might be considering this) and thought that Bitlocker was disabled from the external drive and was not aware that it had to be turned off from the Control Panel System and Security area. I proceeded to install Ubuntu which repartitioned the hard drive.I was curious to see if the new beta release fixed a kernel panic issue I was experiencing and it did not. I now went back to Windows 7 and started the installation. This repartitioned the drive again and everything was reinstalled. I go to plug in my external drive and now I'm prompted for the 48 digit recovery key. Ok, I pull out my jump drive to find that I don't have it. Since it was in my Documents folder and I copied all of that data to the external drive prior to the reinstall, its now encrypted on the drive and I've basically lost all of ... Read more

A:Cannot access external hard drive after enabling Bitlocker to go. Recovery key file is on the encrypted drive and I cannot access it. Any suggestions?

No, without the cert you cannot gain access to the drive, by design, and as expected behavior. If you could, there would not be a reason for the encryption to exist at all.Rating posts helps other users

Hi All,

I have been looking on the internet but can't find anything useful.

I protected data on my USB flash drive using Bitlocker in Windows. But of course I can't access it inside Apple OS X operating system. Yes I have a Windows VM running inside my MacBook and can access bitlocked flash drive this way, but this requires booting
up Window VM and becomes frustrating most of the time.

Does anyone know any possible way to access bitlocked flash drive directly inside OS X?
If the answer is "No", then my request to Microsoft is to please make a Bitlocker Reader/Access tool for Mac OS X and make everyone's life easy. This will definitely increase number of Bitlocker users; a win-win situation!

BitLocker was turned on on my previous Windows 7. It was working properly until I had to change my Windows 7 and reinstall it on another drive, this time SSD instead of HDD. After installing Windows 7, I got "Access Denied" error message when i went
to unlock the drive. The password was correct and the drive could unlock, but access was denied. I tried the built-in Administrator account and found that it had not this problem. It could access the contents of the drive and unlock. This was while my account
was also an administrator of the new Windows. So, I decided to rename login name of the built-in Administrator account to my own and use it instead of my own account. This seemed that resolved the problem. Then, I decided to upgrade this Windows to 10. Now,
after upgrading, I can't access the drive with the built-in Administrator account too!


In my previous Windows which I could see the contents of the drive, I was seeing a tiny lock icon on the root folders (the folders which were located on the root of the drive), while this didn't appear on their sub-folders. What is that?
Now and before upgrading, I might and may access the contents of the drive by using Total Commander. This seems the only way. It can't access and then brings up a dialog and asks for using administrative rights. If I click the button, it may show the contents!
why? I'm the administrator already!
Issues like permissions in security or ownership seem not to be applicable,... Read more

Dear TenForums,

I have a problem with my encrypted 128GB SDcard. First of all I tried to unlock it and check automatic unlock for my computer. I did and SDcard was unlocked successfully. But next time when I switched computer on, I had to unlock SDcard again. I went to Manage BitLocker and tried to turn BitLocker off, but I've got this error message:

"The BitLocker metadata for the encrypted drive is not valid. You can attempt to repair the drive to restore access."

I tried to format SD card after I unlocked it and got this error message: "Windows was unable to complete the format."
I also tried chckdsk but it wants me to format before.

The thing is that I can access and read data on the card, I can erase them, move or copy, create new folders etc. but until I eject SD card or turn off computer. When I switch on the situation is the same, I need to unlock again and there is no change I made about the data.

I'm really desperate

Thanks for any answer

Let suppose I have encrypted a USB pen drive by Bitlocker, Most of the Windows versions have Bitlocker installed and the system prompt for the password, and decrypt the USB drive.
There are certain versions of Windows 7,8,10 like Home Single edition in which Bitlocker is not installed. Now what will happen if I plugged it in a such system, whether it will prompt for the password and decrypt the USB drive or not?

I have 1 partition encrypted drive from windows 7 ultimate, now if i want to change to home premium which do not have bitlocker feature, will i still be able to access the bitlocker encrypted drive?

A:bitlocker encrypted drive

My initial answer is no.. Because Bitlocker is not a part of the lower end flavors of 7 and must be poresent. You should decrypt the data first before downgrading the OS

However, with that said,,, there is the policy you can set within Group Policy for USB flash drives to "Allow Access To Bitlocker-Protected Removable Data Drives From Earlier Versions Of Windows" that can assure that you have access to the USB Flash Drive on other operating systems and computers.

I do not know if this will work on External USB HDD's. I have not played around with bitlocker a whole lot,, need to set some time aside for testing it out.

The Group Policy for this is as follows

In the start search type Group an then click on Edit Group Policy

Computer Configuration / Administrative Templates / Windows Components / Bitlocker Drive Encryption / Removable Data Drives

This policy also shows under Fixed Data Drives. But only mentions FAT file system, if you formatted it as NTFS, I am not sure it will work.

and there you will find the policy.

This policy settings configures whether or not removable data drives formated with the FAT file system can be unlocked and viewed on computer running Windows Server 2008, Windows Vista, Windows XP with SP3, or Windows XP with SP2 operating systems.

But I doubt the data will be recoverable if you downgrade to Home Premium prior to unencrypting it.

I have 2TB hard drive with partitions, one have windows installed on and the other is BitLocker encrypted for data storage. I dont know what happend to my pc while I was at work but my pc was restarted when I got home and now my computer only shows one diskdrive (C, where windows is installed). BitLocked encrypted drive D does not show. It does show when I open disk management but it has no drive letter. See screenshot. What are my options? Please dont tell me that my 1765GB of encrypted data is lost :S

A:BitLocker Encrypted drive not showing anymore

My first bet would be to make a Ubuntu Live cd (Or even better a forensics Helix boot cd but thats probably over the top!), boot into that and see if you are able to mount the partition.. If you can then I would backup the data somewhere if possible... I think im right in saying that you can still decrypt the encrypted data if you copy it elsewhere but I haven't had much experience of bitlocker, only truecrypt.

My personal opinion is not to do anything within Windows as if it doesn't see the data or partition it may start harming your data.... Good to know my 4 years of Forensic Computing isnt going to waste... I think the above is a good start.

Hopefully others out there will have some more / easier suggestions

Hello, I have a drive that I'm trying to retrieve data from and I have the recovery key. It's hooked up to another Win7 64 bit OS and while Windows sees the drive, Bitlocker CP doesn't and therefore is not asking for the recovery key to unlock it.

When I double click it in explorer it just tells me it needs to be formatted.

When the drive was in its own computer, it was stuck in startup repair. Diags returned a HDD error code but I was still able to unlock in natively to run the startup repair.

Any tips or workarounds here or is the hardware damage preventing me from unlocking it on another computer? The only reason I haven't tossed it is because I am able to unlock it when booting from it using the recovery key. So why won't it let me when it's hooked up to another machine with Bitlocker?

I have 2 drives on my PC. One SSD where Windows 8.1 is installed and a secondary HDD for movies and stuff.
The SSD is Microsoft edrive compliant so I just enabled BitLocker encryption and set a password, i.e. Pass1.

Later I also encrypted the secondary HDD and DID NOT save the recovery keys when doing that. I clicked smth like Automatically unlock or smth when doing that as the secondary drive was always available when logging in to Windows later. No need to enter a separate password.

Now, I formatted the primary SSD and re installed Windows 8.1 but now I don't have the recovery key for the secondary drive. Is all the data lost or I can somehow use the password to unlock it?

Thank You

I just started using BitLocker on a Windows7 Computer and am confused about one specific aspect of recovering data drives. I have read through the tutorials on here but I can't seem to find anywhere that explicitly states if this is possible or not.

From this link: Regain access to a computer locked by BitLocker Drive Encryption

I see the statement that "To unlock the drive and regain access to your files, you will need the BitLocker recovery password. If you also encrypted data drives, you will need to have access to the drive that Windows is installed on as well."

My question is if my OS drive dies, will the data drives be recoverable with the password and/or recovery key?

I am not currently in such a situation but I would like to prepare for all possibilities. Since a TPM is needed to store the encryption keys on for the OS drive (I just ordered one but have not encrypted my OS drive yet), are the encryption keys for the data drives are stored on the OS drive itself and this is the issue?

Most of the things I find on Google when trying to search about this issue discuss recovering a data drive that is failing, not a data drive that is in good health but does not have access to the system drive. Can anyone say definitively if this is possible, or do I need to be prepared to lose all data on data drives if my system drive crashes?

A:BitLocker Encrypted Data Drive Recovery Question

Based upon what I have read, your data drives will be UNRECOVERABLE if your OS drive dies. I would consider setting up a RAID 5 array for your OS drive for redundancy, this way if one drive dies, all you have to do is replace it and the missing data pieces will be recreated.

Hello Dears. I had encrypted my drive by Bitlocker in windows 7. 
few days after my friend did quick format in my encrypted drive.
my 300 gb of data lost. and nothing saved
i remember unlock password. 
how can i recover my data ??? i need my data
i tried drive recovering tools (advanced EFS data recovery, easeus . . ,) . but . . . it's encrypted and formatted drive. 
can i undo quick format and decrypt ???
sorry my english is not good.
someone help me please. 

A:Can i recover lost data from encrypted drive by Bitlocker

BitLocker is not the cause of failed to recover files. Format a drive will clear all data saved on the hard disk. Thus recovery formatted data will be a hard disk based technology but not related to operation system. There is no build-in data recovery feature in Windows operations. So we will needto use third party recovery tool or contact third party data recovery company for current issue.

As recovery missing data service will be expensive, we can also check emails and contact friends to see if that can help get a part of files back especially for photos, documents etc.

I accidently formatted one of my drives which was previously encrypted.

Later then, I experimented on a formatted (not encrypted before) usb drive to recover files by same software and it did work.
After that, I encrypted the usb drive and then formatted it. Then I tried to recover by same software, but it didn't work. So, it's apparent that it is not possible to recover from a encrypted and formatted drive by a usual recovery software. Is there any
other method that can help me.

My company is updating our windows, servers, desktops nearly every thing. we were asked to back up all our data on external drives, but we were forced to encrypt the drives with Bit locker, after the immigration to the new hardware and windows 10, I opened
my external HDD and USB Drive using the passwords I set earlier, and as I don't need the drives to be encrypted anymore, I right clicked the drives then choose "Remove password" which I thought it will decrypt the drives and no passwords will be
required anymore. I was surprised to find that my drives are still encrypted, and all what happened is that the password unlock option for my Bit locker encrypted drives was removed. it now only displays to option to unlock (another USB drive or recovery key)
and I don't have both. all what i have is the passwords that I set to the drivers, but the unlock with password option vanished.
can i return that option back so i can unlock both my drives using password? can you please advice?

Team - Trouble here!! Have ~730 GB of data on my 1TB iOmega HDD. Turned on BitLocker on my Windows 7
system, set password, created and saved recovery key file, and i saw it started encrypting (very slowly, which i think is normal). Left it there for hours and when i came back I saw it is asking me for my password for my unlocking... which i entered and it
just wont open. Goes "NOT RESPONDING". I did not lose power during the initial encryption and neither did i pull out the HDD (to my knowledge) even though I read in the MS content that encryption should resume the next time a drive is plugged in,
it it got interrupted the first time or whatsoever.

However, started my research and was shocked to find several people have had similar problems. Also references that data must be backed up before encrypting (may
be common sense). Well, i have not done that, did not know that a simple of act of encrypting could be such a crime, especially when you are encrypting what you have just taken a backup off - before proceeding towards a formatting of my laptop.

Tried the manage-bde commands and the results are in a pic that i cannot attach. Interestingly, i find that the "manage-bde -status" command shows "conversion status" and "percentage of encryption" as unknown. Is this normal? I

A:New op sys, can't access encrypted ext. hard drive

If the files weren't really encrypted but just passworded and made "private" you need to change ownership, follow this

If instead we are talking of NTFS encryption, things get more complex.

If you remember the password you used to encrypt them (you can try the old account password or the admin password of XP) you can try this, or this. or google for similar programs.

But if you nuked the old OS and used this kind of encryption I think you're in deep trouble.

I have an older Laptop that operates on  Windows 7 Ultimate,I have the Bitlocker Drive Encryption on and encrypted for Drive C:   I now started the process of encrypting my external usb hdd Drive E: which has a long way to go for it's large
size. During the encryption I needed to disconnect it so I paused the encryption like it says to do before removing or changing any files on it. I then plugged my drive into a newer laptop I have that operates on Windows 10,. I was prompted for the Bitlocker
Drive Encryption Password screen like normal just like on my Windows 7 laptop so I enter the password and it was correct and it began the encryption process again. When I finished with what I needed to do on the Windows 10 laptop I paused the encryption again
and disconnected the drive. I am now back on my Windows 7 Ultimate OS and plugged the drive in, Bitlocker Encryption Password Screen comes up again and I entered my password but now for some reason it's saying the password is incorrect?  "But It's
not incorrect",is there a reason why this has happen and a way to fix it? My second issue is that I have the recovery key written down on paper but on the fifth line of the eight lines that makes the recovery key I left out a number,did not write it correctly,
there for I cannot just reset my password using the key and get back to normal again. Any way to find the lost number to the key? As I do have the rest of it written correctly please help tha... Read more

I'm a long-time reader but new poster. I am currently running Windows 7. I want to install Windows XP onto another disc and have a dual-boot setup. I keep Windows 7 up to date and secure, but for the XP partition, I would rather not have antivirus running or even installed, in order to limit background processes. I will not be logging into any place or making any credit card purchases when booted into Windows XP. It will just be used for surfing, games, etc. Further, if and when XP becomes compromised or buggy, I will simply overwrite the partition with a backup image.

If I use Bitlocker to lock down the Windows 7 partition (with the encryption key on a thumb drive) and boot into Windows XP, am I correct in thinking the XP installation see or can't access the Windows 7 partition? If XP gets compromised, can a virus access or write to the Windows 7 partition?

Is there any other reason why this would not be secure? Can a virus write to the BIOS?

Thanks to anyone who can help.

After rebooting one of our test machines, bitlocker wanted the recovery key.
There were no hardware modifications on that machine.
Error message in event log:
Bootmgr failed to obtain the bitlocker volume master key from the TPM because the PCRs did not match
Event id 24635, source bitlocker-driver
 Each time the machine starts, the recovery key is needed.
Any idea how to solve that issue and why it happens?
Second partition was created manually on that machine. So that's clear that bitlocker reacts...
But now: how can I confirm those changes so that the recovery key is not needed each time we boot?

A:Bitlocker enabled drive, recovery key needed during boot, PCS did not match, event id 24635, source bitlocker-driver

I would like to confirm if BitLocker accepts the recovery key?
Please update the BIOS to improve the stability for TPM first.
I also would like to suggest you disable and enable BitLocker again to reset the settings.

I am trying to map network drive using Windows 8.1 64-bit.  The drive is a USB disk plugged right into my router.  The drive location is //  If I do the following at a command prompt, it is successful and I can read/write
to the USB drive using file explorer at //
net use \\ /USER:admin (and typing in the password when prompted)

However, if I try to use the Map Network Drive tool (while selecting the "different credentials" option) something weird happens.  The Windows Security box pops up to enter my credentials but then immediately a second box opens up
titled just "Windows".  The box says:
The mapped network drive could not be created because the following error has occurred: Attempt to access invalid address.

Also, if I use Remote Desktop Connection to try and connect with my computer at work I get a very similar situation.  A Windows Security box pops up to enter my credentials followed immediately with a box with the message "Remote Desktop
Connection has stopped working".  I know it should work because I created a .rdp text file with my username and encrypted password in it and then I can connect!

I'm thinking something must be corrupt in my registry.  The only security software I run is the stuff that comes with Windows 8.1, pretty basic machine setup quite frankly.  A system restore is my very last option because I don't know
when the probl... Read more

I've never seen this before. Double click on e:\ in my computer and it says not a valid win32 application. Seen it when opening applications but not a drive! all other drives are fine. First time i saw it it was looking for install.exe, which i remember deleting a week or so ago. Most likely because it was a missing shortcut in registry or because it was corrupted or something simular. I dont know what to do about this, as I said never seen it happen b4 on a drive. You can open e drive when you right click and explore but when double click sometimes it tries to locate install.exe. No virus, but did have a few recently, I wont put it down to that though and dismiss because I am very vigilant and remove virus immediately, and scan twice a day, always scanning b4 opening apps. Weird one! Logically, how do i stop it looking for install.exe when openning?

i recently used xp system restore after a virus attack caused windows not to start. xp started the system restore automatically after login, i had no choice. it then did something for a few seconds and locked up. i only had to go back to the last restore point to recover everything. i am virus free.

but now i can't access my encrypted files. i get "access denied" even tho i created the folders with my admin account.

xp has created a new admin account with the same name and password. i can see both accounts have a CA Root cerificate that is not trusted.

i tried adding my new user account by using the encrypted file properties to gain access, but xp reported "error in adding new user. error code 5.", which is a big help.

how can i get access to my encrypted folders/files again?
i hope somebody knows the answer, thanks.

Long sad story. Please bear with me.

My drive was dying but was still recoverable using commercial recovery software. Unfortunately, I only did a partial recovery and when I tried again, the drive had failed further to where there was no longer a drive letter and the commercial recovery software was no longer an option. So I tried Recovery Console but got "windows could not start because the following file is missing or corrupt: system32\drivers\ntfs.sys. So i installed a floppy drive, and tried to copy a new ntfs.sys onto the hard drive but i got "access is denied". The i tried a dir on the c drive and i got "an error occurred during directory enumeration". Following some other online discussions I tried a "fixmbr" which was successful but accomplished nothing. Then i tried "fixboot" and got "fixboot cannot find the system drive, or the drive specified is not valid". I've also tried chkdsk /r and got "the volume appears to contain one or more unrecoverable problems".

The drive is a Western Digital 400gb (wd4000yr) and i'm on an xp pro hp system.

Short of paying a gazillion dollars to DriveSavers, anyone have any more suggestions? I'm nearing the end of my rope!

thanks in advance

A:fixboot cannot find the system drive or the drive specified is not valid

It sounds like you have some physical problems with the hdd. I would to to the Western Digital web site and download their diagnostic tool and run it. This should provide you with an accurate account of the hdd.
