Windows 10: Unable to access hard drive after encrypting it using Bitlocker

Hi, I attached a removable hard drive with my office laptop. I mistakenly choose to bitlocker encryption. Bitlocker started encryption and stopped at 76%. After waiting for long time I removed it from laptop. After that I tried to read the data using my office laptop and home computer but failed. It asks for password but even I provide correct password, it is not working. I printed a copy of Key but not sure it is the correct key. Could anyone please help me so that I can recover all the data?


***Original title: Bitlocker partially encrypted my hard drive - password not working - unable to read data.***

Unable to access Bitlocker encrypted External drive

Bitlocker is tied to the OS you installed it on. If you cannot access the old HD you cannot gain access to the bitlocked drive.
