If you know the password and simply want to remove the "Exclusive" lock, follow these steps in your BIOS: How to Remove a Hard Drive Password - Acer Community
It sounds like you're trying to access a hard drive that's locked with an "HDD Password" (often called HDD Exclusive Mode on Acer laptops). Unfortunately, Acer customer support cannot unlock the drive remotely — they don’t have master passwords for user-set HDD passwords due to security and encryption.

If you contact Acer Support, they will require:
