Receiving bitlocker error in Event Viewer whenever i attach an external HD to my desktop (non are encrypted with bitlocker)
Hello All, Seem to be having a problem recently. Whenever I attach any external drive to my Desktop I receive the following error in Even Viewer. I never encrypted any of the drives in question with bitlocker. Encrypted volume check: Volume information on \\?\Volume{7cc70383-5d6b-11e0-855c-001c25a5a540} cannot be read. Event ID: 24620 And I cannot access my drive information. At first i thought it may be an issue with one of the drives I have partially encrypted with TrueCrypt but I tried several other unencrypted drives and I receive the same error and I cannot access the data on my drives. I tried to access the Bit Locker Recovery tool program (downloaded the VISTA Version since there was no Windows 7 Version that I could find), but it did not allow me to install the recovery tool to attempt some kind of fixing. The strange thing is that I do not have Windows 7 Ultimate installed (which from what I understand is the only way to have Bitlocker). I have windows 7 professional and I never encrypted my drives with bitlocker, 1 out of the 3 drives is partially encrypted with TrueCrypt, the other 2 are not encrypted with anything. The stranger thing is that I can plug the external drives to another laptop and I can access the data fine with no problem or errors. I searched the forum for simliar problems, but did not see any responses with fixes to this issue. The only thing I can think of is that my Desktop downloaded and installed a bunch of Windows Updates within the last 4-5 days. heres is the update list http://farm6.static.flickr.com/5304/5890096650_431b0f3627_b.jpg Any assistance in attempting to figure this out would be appreciated.

Hi, According to the error message, it should use BitLocker Repair Tool to fix it, refer: http://technet.microsoft.com/en-us/library/cc734057(WS.10).aspx What error message did you receive when you use BitLocker repair Tool? I notice one drive is encrypted with TrueCrypt, please use that program to unencrypt the drive for test. If it doesn’t work, since the issue didn’t appear before, you can try to perform a system restore to see the result. Hope that helps.
