BitLocker decryption stuck, what to do?

I was trying to decrypt a BitLocker-protected external hard drive overnight and it seems to be stuck at 52% decryption completed. I then paused decryption and opened up the error checking tool but it didn't complete but in the process, I agreed to turn off access to the drive during the "error check" that doesn't seem to have happened. 

Btw, there's over 2TB worth of some pretty important data on this drive so can someone please help? I'd be willing to pay a reasonable amount for a software solution.

Method 1: Pause BitLocker decryption and resume

  1. Open the BitLocker Drive Encryption in Control Panel (Start, Control Panel, BitLocker Drive Encryption).
  2. On the BitLocker encrypted drive, select "Suspend Protection".
  3. Click "Yes" to the confirmation.
  4. Select "Resume Protection".

If the above steps cannot resume BitLocker decryption, please try the following steps:

  1. Safely eject the BitLocker encrypted external hard drive.
  2. Change another USB port to plug the BitLocker encrypted external hard drive in. Or connect the BitLocker encrypted external hard drive to another computer.
  3. Right-click on the BitLocker encrypted external hard drive in My Computer, select "Unlock" and then enter the password or 48-digit BitLocker recovery key to decrypt again.
