Not only i want to low level format it, i want to reinitialize it, factory reset style, like some kind of HDparm but in the deepest level, like, absolutely destroying every sector and or hard drive settings.

Well, you could overwrite every sector with zero, if you're absolutely positively sure you don't want any more data off the drive...

dd if=/dev/zero of=/dev/sdx

(where x is your drive's letter, see lsblk or fdisk -l to be sure FIRST)

And probably adding bs=1M or bs=5M might help too, to read/write in 1 MB or 5 MB blocks, should be ok for the hard drive, a little (maybe a lot) faster in case it defaults to a block size of 512 bytes
