If it's truely a bios password, you can yank the power, open the machine, remove the battery from the motherboard, and press the power button to completely wipe the bios settings. That usually gets rid of any bios passwords.

Khyer123, a true hdd password is not saved in the bios it's saved on the drive. On most modern laptops removing the the bios battery and draining flea power will reset the bios defaults but won't reset password saved in nvram, as nvram isn't affected by power loss.

Worded, it depends on the drive some are on just the pcb and others are on the pcb and the platters. Plus when swapping a pcb you have to get one thats the exact same pcb revision and firmware version as the one being replaced. Usually a forgotten hdd password = paperweight.

I had a case in past where the password was set to RAID controller. To get rid of it I have to update\upgrade controller BIOS.
But still there are drives with pass set on HDD.
