after following : Scenario 16: Using the BitLocker Repair Tool to Recover a Drive http://technet.microsoft.com/en-us/library/ee523219.aspx after 100% decryption .. cannot preform chkdsk to the target partition.... it says : The type of the file system is NTFS. Unable to determine volume version and state. CHKDSK aborted. and when trying to access the drive it shows the same old error : drive is not accessible the parameter is incorrect

If you have 100% decrypted the drive, bitlocker is no longer valid. Sounds as if you have some other permission issue, dont know sorry. Try standard checkdisc route.

the repairing process is to move data to another drive.. it was don successfully but the target partition is not accessible and can not preform chkdsk to it.... the parameter is incorrect

Hi , To check if the drive is fully decrypted, please use manage-bde status to export the Bitlocker status and post it here. Do you use an external hard drive? If so, I suggest you reinstall the external hard drive driver and test the issue. 1.Plug in the external hard drive, click Start, type devmgmt.msc in the search bar and press enter to open Device Manager. 2.Expand the USB list, find the device, right click Uninstall, disconnect the external USB hard drive, then reconnect the drive and reinstall the driver. Hope it helps.Tracy Cai TechNet Community Support

yes it's an external drive status : Disk volumes that can be protected with BitLocker Drive Encryption: Volume H: [] [Data Volume] Size: Unknown GB BitLocker Version: Windows 7 Conversion Status: Fully Encrypted Percentage Encrypted: 100% Encryption Method: AES 128 with Diffuser Protection Status: Protection On Lock Status: Unlocked Identification Field: None Automatic Unlock: Disabled Key Protectors: Numerical Password External Key External Key

Hi , The result indicates the drive is still BitLocker-protected. Use the following command to decrypts the drive and turns off BitLocker. manage-bde -off More information about Manage-bde: off, please see: http://technet.microsoft.com/en-us/library/ff829857(v=ws.10)Tracy Cai TechNet Community Support

i can not decrypt the drive .. when i try it shows me this error ERROR: An error occurred (code 0x80070057): The parameter is incorrect. and when i followed this article to repair it http://technet.microsoft.com/en-us/library/ee523219.aspx it finished decryption 100% . but when i try to access the target drive or use chkdsk it shows the same error "The parameter is incorrect."

Hi , According to the error message, it will occur if you do not have a separate active system partition on the operating system drive. To enable BitLocker Drive Encryption on the operating system drive, a separate, active system partition is required. The system partition contains the files needed to start the operating system, and the partition cannot be encrypted. In Windows 7, a separate, active system partition is created automatically. However, in some rare situations you may need to manually prepare the drive for BitLocker. Please see this KB article: http://support.microsoft.com/kb/2019926 Use the following bdehdcg.exe command line to create a system partition for BitLocker. For more information, see the BdeHdCfg.exe Parameter Reference.Tracy Cai TechNet Community Support
