thank you very much for your help thus far, but unfortunately it doesn't help as my iomega drive stuck at just over 90percent decrypting action. When i tried to restart the process it started querying for the password, which password doesn't work anymore and well i dont have the recovery key as i have already formatted the physical harddrive sometime back to reinstall win 7; any possibility of recovering my external drive data ??? thank you again balakrishnan

With no key and password, you are pretty much out of luck, thus the functionality of bitlocker is working to prevent unauthroized entry to a drive with no key or password. Reformat the drive, and move on.:P Advice offered, If you need more help it is advised to seek the council and advice of paid professionals. The answer is always 42, or reboot.
