How can I access my hard drives that are password protected?

It sounds like your drives might be encrypted with BitLocker. If that's the case, you'll need to decrypt them from the PC where you initially activated the BitLocker encryption. Have you checked that? If you do have access to that PC, log in and try removing the encryption.

I understand this can be frustrating! If you bought multiple tablets and they're all showing the same issue, it might complicate things. Unfortunately, without the right password, accessing them could be tough. There are programs that claim to unlock encrypted drives, but their success can vary. I’d recommend checking with the seller if there was a way they intended for you to access these drives.
