1. Explain what happens to the data after we remove it from the hard disk.

$\huge\red{Answer}$

When a file is deleted, the operating system deletes the pointers to the file and in the FAT or MFT the space occupied by the file is mark as available.

When the computer removes the pointers to computer files, the data remains on the hard drive until the computer over-writes the file with different data.

Answer 2

Answer:

Simply put, when you store something on a hard drive, we are coding magnetic nodes on the drive in 1 and 0. A electrified node is a 1 and vice versa. So basically we are telling the computer what those 1 and 0 are ordered in from the drive.

When you delete a file, you Dont remove it from existance. You are basically marking it as empty. So the next time the computer needs space to store data, it will use that and rewrite that data. That's how you can recover data from deleted files. By finding that un overwritten nodes.
