I have a storage partition used only for documents, music etc. (no the system partition) that is encrypted with BitLocker in Windows 7 x86. It's become unusable now, for some reason. It's still being read as a BitLocker drive, and can also be unlocked using the password - the icon changes from locked (closed gold padlock) to unlocked (open silver padlock). Each time I reboot Windows it appears as a locked drive/partition, which is normal. However, I can't use it - it needs to be formatted, apparently. What can I do - this is the really, really important partition - it contains all my work, essays, letters etc. Any help would be really appreciated.
