Help with BitLocker

[Crossfade]

Yesterday i turned bit locker on and encrypted the D: drive. It's a separate HDD that i use to store data.I saved a key on my flash drive.When it was finished i started the decryption.All this just to test what Bit locker does My God am i a Noob.And after a few hours of decrypting some error pop up at lets say 95% done decryption.And computer jammed.I assumed it was becouse my C: had low space and ....Thats the story.
Now i turned on my computer and System starts to load and get stacked at Windows logo and it stays that way the whole day (I tried).When i unplug the Partially decrypted drive it all works well,but when i turn it back on nothing,jams at Win logo screen.I also tried the other computer but same situation System wont boot in any mode....Please if anyone got some info on how to fix this ???

Remove the encrypted hard drive so you can boot your PC.

Then connect it (via an external USB adaptor or similar) then try to decrypt again.

How big is the drive you tried to encrypt?

Remove the encrypted hard drive so you can boot your PC.

Then connect it (via an external USB adapter or similar) then try to decrypt again.

I tried that and my windows explorer hangs .I can still go to task manager and start command prompt but the drive is not mounted i guess.Or its not recognizable.

How big is the drive you tried to encrypt?

The drive is 250GB and its not external but a SATA HDD

Read through this and see if any of it helps (the steps should be the same for 7 aswell as Vista): How to use the BitLocker Repair Tool to help recover data from an encrypted volume in Windows Vista or in Windows Server 2008

SOLVED ) This is what i done.I downloaded a Western digital HDD diagnostic tool (Diag504fCD.iso) Burned it on CD and turned off all hard drives exept the one that was messed up.Inserted the cd ,boot from it and on the fast test i got an error.Then i performed the deep test that lasted for about 45 minutes ( sleep for that time ) and voila the disk is ok i Boot my system and some dangerous Red screen appeared OMG but i selected the first option from the menu.Windows boot good and i got a bitlocker icon notification that bitlocker was paused decrypting at 93,4 % and he just went on decrypting )) And that's it ...Thank you all for your guides on this .... )))) Got my pictures back weeeeeeeeeeeeeeeeeeeeeeee......
