If you have a hard drive of unknown origins there are times when you just can't format it using the normal methods like an OS's installer or Windows built in Disk Configuration Utility. NTFS's good old security tries to do you dirty as well. It can be a real pain in the ass.
But AtA has been through this MANY MANY times and we know of an old school solution to blowing away almost any fussy hard drive.
Is Dos 6.22 old enough for you? Fdisk and format are your friends... You didn't forget about them did you? 6.22 is before NTFS so it doesn't worry about the security - isn't that special?
Don't worry loyal AtA fan we won't make you go scurrying back to your domicile looking for your old dusty box of floppy disks because we have an image for you right over here...
You can use this with a blank floppy disk to boot into 6.22 and get down and dirty. How do you deal with formating issues? Hit us up in the comments.
