Hello Everyone,

THis morning I tried to login to my windows machine, windows 10 pro, intel i5 3.30ghz, 12gb RAM, 2TB HD. and kept telling me password was incorrect. I then removed windows password thru other admin user, and now all external hd's except for c: drive all lecked by bitlocker. Never installed or activated it. I have 2 internal sata drives and 2 usb drives locked. I have gone to control panel, bitlocker, and tried to unlock drives, tried to do a search for key id on pc and nothing is found. Please help me as my raw files are in the backup drives. Any suggestions, your help is greatly appreciated All my files in c: drive are usable and not locked at all

Have you scanned for malware?

Have you tried the external drives on another computer?

 

I have no knowledge of BitLocker, so I'm of no help with that.

Dont know if this will work

 

 

Open an Administrative Command Prompt and type the following

 

manage-bde -protectors c: -get

 

replace the drive letter c: with whatever drive is encrypted.

 

you’ll see output something like this

 

BitLocker Drive Encryption: Configuration Tool version 6.2.9200
Copyright © 2012 Microsoft Corporation. All rights reserved.

 

Volume C: [OSDisk]
All Key Protectors

 

TPM:      ID: {37CE71B7-8FE4-4CA9-9637-42516F599C02}

 

Numerical Password:    ID: {31514A2F-147C-478C-B6A2-618CD6F66653}

 

Password:

Good morning Wolverine,
 

Unfortunately command did not work!

I am going to try the recovery for now, and hoping to somehow find a way to find or convert numerical password into 48digit password if possible.

Will keep you posted of outcome!!! Thank you

I don't think this is possible.  Bitlocker "leaves footprints" on the devices in question and most use of restore points does not change "user data," and Bitlocker is considered a user action.  If this were not the case then taking an external disc drive that had been locked using Bitlocker to another machine would allow it to be "plug n' play" with no locking there, but it doesn't do that.

Yes your right,the drives are encrypted in themselves,i was thinking outloud i suppose,very frustrating this in that he didnt actually invoke Bitlocker..

Hello Everyone,

 

I called Microsoft and that was as useless as never placing the call.

Here is what they had to say:

The reason why bitlocker invoked itself was because windows 10 felt a security issue was present;

On the last update that came down the pipe, system was automatically restarted, when I tried to login I  kept getting a message that password was incorrect. The user profile (mine) was corrupted during the update. When I logged to my wife's account, and removed my password windows locked my drives, and the only reason the C: drive was not locked was because I had a secondary account. He stated that Microsoft was not responsible, they could and would not be able to help me, I should seek a local data recovery expert and wished me "good luck" and that was end of call.

I have not given up on trying to recover my drives and data, been busy and need to start setting aside recovery time and effort :-)

 

Please if you hear or find any possible solution to this issue feel free to contact me.

 

Would love to Thank everyone for their great help and comments, Happy Thanksgiving Everyone!!!

Just a shot in the dark here, but does the pc have a TPM chip and did you have a MSFT account and PIN password prior to this happening? Reason I ask, MSFT I believe stores your bitlocker keys in your account.
