to adjust the interleave on your RLL hard disk.

I was strictly MFM. Although I was interested in ESDI. And my WD controller did need me to use debug to low level format.

I was amazed at the time to learn there were utilities in ROM between 640k and 1 Meg. A genius at work put me on to this and I was able to get a big performance increase by increasing the interleave on my whiz bang 10 Meg drive. All the storage ANYONE should ever need!
