Before reading, note that I have already tried to download the BitLocker Repair Tool, but it says its for Windows Vista, but I'm on Windows 7. It won't let me download and install the Vista version.I have a USB flash drive that I store files on. For the past 2-3 months, I've had no issues. Then I started noticing (about a week ago) that a small number of files (less than 5) couldn't be opened. Then, today, I noticed a few more. So I figured I'd better copy everything off of the drive to another, non-BitLocker drive. In the process, I kept getting prompted by Windows to scan the drive for errors. If I selected the scan, the folder windows for the BitLocker drive would close. If I selected "Continue Without Scanning" it would copy the file. But about 20 minutes into the process, I started getting prompted for the password for the BitLocker drive. I enter it, and immediately I am prompted to enter it again. (I'm entering the correct password because it does NOT give me the INCORRECT PASSWORD message--I tried entering a wrong password once just to make sure and I got the INCORRECT PASSWORD message.) It just keeps cycling through the password entry screen.Obviously my BitLocker to Go installation on the USB drive has become corrupted. How do I fit it if my system is Windows 7 (and apparently there's no repair tool for Windows 7)?

Hi Brent37, What exactly happens when you click on download button?BitLocker Drive Encryption is an integral security feature in the Windows 7 operating system that helps protect data stored on fixed and removable data drives and the operating system drive. BitLocker helps protect against "offline attacks," which are attacks made by disabling or circumventing the installed operating system or made by physically removing the hard drive to attack the data separately. For fixed and removable data drives, BitLocker helps ensure that users can read the data on the drive and write data to the drive only when they have either the required password, smart card credentials, or are using the data drive on a BitLocker-protected computer that has the proper keys. To repair a BitLocker-protected drive by using Repair-bde 1. Open a Command Prompt window as an administrator.a. To do this, click Start, type cmd in the Search programs and files box, right-click cmd.exe, and then click Run as administrator.b. If the User Account Control dialog box appears, confirm that the action it displays is what you want, and then click Yes. 2. At the command prompt, type one of the following commands, depending on which recovery information you want to use:a. To repair using a recovery password: repair-bde C: Z: -rp 062612-026103-175593-225830-027357-086526-362263-513414b. To repair using a recovery key: repair-bde C: Z: -rk F:\RecoveryKey.bekc.

Hi, Umesh's suggestion is worth to perform. In addition, to troubleshoot the issue, I suggest you move the problematic USB drive on another Windows 7 machine and check whether it can be read or copy normally. If the issue persists, please also try a Check Disk for a test. Thanks, Novak
