Summary

Non-free media information and use rationale true for Disk formatting
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.
Source	IBM PC XT with 640 kilobytes of memory, text-only monochrome video, 360k floppy drive, Western Digital MFM drive controller, and a Seagate 10 megabyte MFM hard drive
Article	Disk formatting
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.
