Windows 7: Another bitlocker problem!

After upgrading to windows 7 ultimate the other day I thought I would try out bitlocker, and locked a small 10gb partition on my hard drive no problem, then thought ok I'll do my portable HDD, so it started encrypting and got to 1.7% and said that I needed to run chkdsk /r so went into CMD and repaired it along with doing it in the tools menu on the drives properties, so tried encrypting it again and it got half way through after taking a few hours to do the 1st half so paused it and shut it down, booted it up the next day and it asked for my password so entered it and now it just hangs on the unlock wizard, does the same on another windows 7 laptop!

I have tried to unlock it in the CMD and which hasent worked, any other way I can unlock it to get to my files!
and formatting isnt an option, all my music/films/uni works etc are on there! and I really need it back!

help!

Cheers

Did you make a recovery key and save it to a flash drive?
See Diagnostic and Recovery Tools (DaRt) Overview of Microsoft Diagnostics and Recovery Toolset

yep, tried entering the key and it does the same, not responds....

Did you click on the link I posted earlier --> Diagnostic and Recovery Tools (DaRt)

Yep I ha a quick look and seemed like it was more for formatting etc but just had a closer read and there should be some things that can help thanks, i'll give it ago

tried that, diddnt work im really stuck as its got things I need for uni on there :@

You have a bad harddrive or at least a bad spot an the platter. I have a 250 GB hard drive with a bad spot on the platter that causes it to completely lockup. The only way to really use the harddrive is to have the first partition set 160 GB, the second partition set at 10 GB and the third partition set to 40GB. Then I delete the second partition as that is where the bad spot is on the platter.

but I cant get into it to create a partition not even in the recovery console....

Well if the encryption process has failed part way though then recovery will be impossible to say the least. This is why you never encrypt a large HDD or partition with data on it. Encryption is very sensitive to any form of corruption, one bit out of place can bring the whole thing crashing down.
