PREP - Hard Disk Low Level Format (2615)

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.

PREP erases all data on the hard disk.
If at all possible, always back up the data on the hard disk to diskettes before running PREP.
