Description

Example of obsolete 1987 software program for low-level formatting MFM/RLL hard drives, to recreate track and sector boundaries, check for media errors, and to also configure the sector interleaving.

Portion used
Low resolution?

image is 500x455, and was taken with a handheld digital camera of the IBM PC XT monochrome monitor. Slight camera shake so the image is blurry.

Purpose of use

Documentation of the obscure low-level formatting process that was once common with early IBM PC MFM/RLL hard drives, typically under 50 megabytes in total partition size.

Replaceable?

This image generally cannot be replaced by free content. Low level formatting cannot be done with modern IDE/SATA drives. This function was typically solely performed by utilities provided by the hard drive or MFM/RLL controller manufacturer.
