Re: I am looking for a DOS based low level format-ing hard drive and SSD drive
We need to make the distinction between low level format and doing housekeeping maintenance. VC servo tracks have a chicken and egg problem if you're trying to rewrite them, and as this truly is at the lowest level, this can't be done on VC disks.
Fortunately on stepper disks the lowest level does not contain servo data, just sector boundaries, so it's a lot simpler on these older disks.
