Have checked your bios and found a password twice in different sections, the first one is the system password and the second one is for the hard drive, both are the same.
password = 1750

Why don't you post your Model Number, it may be on my list and may provide you with the info, supposing that the password can be extracted from your BIOS file.
For the file of post #1 of this thread, download it and also download UEFI Tool NE version, do a Google search if you don't know where to get it.
Open the file with UEFITool NE and double click on BIOS REGION, the first padding file at offset 3000h is where the scan codes are located for the system password, in this case:
04 0208060B E1
- the "04" is the number of characters that the password has, in this case the password is 4 characters long (N=4).
- the next N bytes "0208060B" is the actual password stored in scan codes (Google search for "keyboard scan codes")
02 = 1
08 = 7
06 = 5
0B = 0
- the "E1" is the checksum (8-bit addition) of all bytes including itself, which result must be 00h.
(04h+02h+08h+06h+0Bh+E1h) & FFh = 00h
The hard drive password is also stored in a similar way, but in this case is stored in UEFI Variable "SaveHddPassword", starting at offset 8 of variable, stored in Unicode/16-bits (scan code too).

@smali
The older the hard drive, the better possibility you have to recover/clear its password.
Look for HDD specialized forums like hddguru, hddoracle, other.
Many questions:
- How old is the hard drive?
- Was this hard drive installed in a laptop that uses a master password recovery algorithm?
- Look for hard drive label, it will give an idea if it was installed/locked in a Dell, HP, Lenovo or other manufacturer laptop.
Unless you have something very important you want to recover from this hdd it will be worth, otherwise look for a replacement.
Passwords are stored in the HDD platter.
By taking a look at the file you uploaded seems to be from around 2008, HTS7250xxA9A300 model.
There's a ZU (Zung Unlocker) utility, give it a try, by the age of the HDD you may get lucky with it.Last edited by AAAC; 09-17-2022, 06:11 PM.
