Bitlocker decryption stuck/frozen, what to do?

Updated by Tim to Bitlocker Recovery Tips on April 11th, 2020

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.

Solution 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 drive, select "Suspend Protection".
