How to write to a specific hard disk space?

Question

Hard disks

There is a 640GB hard drive with approximately 1,200,000,000 LBA blocks in it.
In blocks starting from 30,000,000 to 300,000,000 there are Bad sectors, after 400kk everything is perfectly clean.
It's a pity to throw it away, I plan to use it as an external one.
The question is, with what program can you create a partition that will not be visible from under Windows and completely clog the disk area from 0 to 350,000,000 different junk files?
ps It's just that as far as I know, when writing, Windows and linux evenly distribute files throughout the disk + leave a certain amount of space between files to reduce fragmentation.
Maybe someone who has come across has their own "day off" work?

Answer 1

Any utility designed to work with the disk. The same mhdd can write to a specific range of blocks.

Answer 2

You can create multiple partitions, and do not assign a letter to the first one.
