Can I use BitLocker To Go with computers running Windows XP or Windows Vista?
Yes. By default if the removable data drive is formatted by using the FAT file system and then locked with BitLocker To Go using a computer running Windows 7, it can be unlocked on a computer running Windows XP or Windows Vista. However, the files will available with read-only access on those operating systems and no files will be able to be added to the removable drive from those computers. When you insert the removable drive into a computer running Windows XP or Windows Vista, the only readable file on the drive is the BitLocker To Go Reader application, which is automatically written to the drive when BitLocker protection is turned on for the drive in Windows 7. By running the BitLocker To Go Reader, you will be able to view the files on the BitLocker-protected removable drive.
