Cannot re-enable Bitlocker after formatting external drive

Question

Had BL running on an external drive. I had to format the drive because it was acting up and now I can no longer get BL to run. I get a message that refers to "bands not being enumerated." Cannot get it to encrypt again with BL .Lots of suggestions out on the internet but none so far seem to work. I'm fine wiping the drive clean since I already formatted it. The drive is visible in Windows Explorer and from a CMD screen as a regular drive, as well as under "Manage Bitlocker" under Bitlocker To Go (but cannot enable). From a CMD prompt it does appear as a disk and the volume info says "healthy." Any suggestions?
