You’ve used BitLocker drive encryption to protect the contents of a USB flash drive. So what happens if you insert that drive into a PC running Windows XP or Vista? In that case, Windows displays the dialog box shown here. When you enter the correct password, the contents appear in the BitLocker To Go Reader, shown here. As the name suggests, you can copy and open files from this location, but you can’t add new files or change or delete existing one. (The BitLocker To Go Reader does not work with OS X; to read an encrypted drive on a Mac, it must be running Windows.)
