PREP — Hard Disk Low Level Format
The PREP utility initializes and prepares the hard disk
surface for the storage of data. It performs a low-level
format, then checks for bad sectors. If any bad sectors
are found, they are marked in a way that prevents data
from being stored in them.
There are two situations where PREP is used.
To prepare the hard disk drive surface for formatting
when installing a new hard disk drive.
To exclude sectors of the hard disk that have become
unusable, indicated by intermittent or continuous hard
disk drive read failures.
