As long as it is just a bad spot on the platter and the head that reads from the platter is not the problem, you should be able to use different computer to format you harddrive. This will stop your current commuter from resuming the encryption process where the fault is located on the harddrive. That is of course if the harddrive in question is not the primary drive and you don't have data loss worries.

It looks like from your original post you have not enabled the auto unlock feature, from that computer just don't unlock it and instead try a quick format. After a quick format try to use your recovery tools.

but wont I loose everything? would rarther try and save as much of it as I can, 300gb of films/music/games and uni work.

Is there anyway I can turn the auto unlock feature on without having to unlock the drive?

You can turn the auto unlock on, but from what I gather, try to resume it's encryption on the bad spot on the harddrive thus causing it to hang. I don't know if you can decrypt the drive without unlocking first but you could try.

Performing a quick format doesn't really delete your data as it doesn't over write each sector on the harddrive. I am not familiar with the types of software used to recovery data in this kind of scenario so I couldn't help you there. I don't think you would be able recover data that has already been encrypted. The first thing I Would try to do is make a backup image of that harddrive (if it will let you) then try to restore that image to another drive of the same size. I don't know how this will turn out as far as the encrypted data goes, but maybe you will be able to decrypt your data.

For using Bitlocker to encrypt a hard disk,a full process is required,
you cannot pause on the half way and shut it down,
notice that when you encrypting your hard disk and you tried to close that process is impossible,
since the drive is encrypting,this is not like the one call EFS encryption,
EFS encryption can pause on half way and continue after shutdown the computer,but Bitlocker cannot.

I think you should try to continue encryption first if possible,
then decrypt the whole drive.

Glad to hear it!
Make sure you use the bitlocker carefully,
or just use it for the flash drive(small capacity) only.

A big hard drive would be better to use bitlocker when you start to use it,
nothing inside to lower the risk for losing data.

If you're not sure how it works,don't attempt it on your important hard drive,
or any data drive.(Same with EFS encryption)

Win 7 Home Premium with SP1
 
 

Hello,

I have 1TB HDD and I was Encrypting it with Win 7 Ultimate, having 800GB data in it. Sadly, the HDD has external supply and it was disconnected from that power supply during the encryption. It stopped around 94%. Now, when I am trying to decrypt it, it has stopped at 84% for almost two hours. Please help urgent.

Update:
Also, when I tried to see its status with manage-bde the following:

Volume I: []
[Data Volume]

Size: Unknown GB
BitLocker Version: None
Conversion Status: Fully Decrypted
Percentage Encrypted: 0%
ERROR: An error occurred (code 0x80070057):
The parameter is incorrect.


But the decryption is still going.

Update 2:
The repair copied most of the files but it does not give access for the folders inside.
