NOW You Can Make a 360k Disk drive into a 720k Disk drive A 360k 5.25 inch disk Cannot Support 720k, a HIGH Density Disk Can So By a High Density Disks and Follow Example Bellow :) A>SETUPSL/A Then use the Down Arrow Key Or up Arrow Keys when you see the option 360k 5.25inch, Use your Right Arrow Key to change the Option to 720k 3.50inch. After that Press F1 Then Run your FORMAT command on your High Density Diskette this will Give you 720k Room on a 360k Disk drive. All that is going on is that you are Confusing the Drive Controler in to thinking your 360k 5.25inch disk drive is a 720k 3.50inch disk drive. The Reason you cannot yous your 360k Diskettes is that there is no ROOM for 720k on the Diskette, so in other words you end up reading the Plastic SHELL of you Diskette LOL :) so use a HIGH Density Diskette and the Example I showed you above you should be happy with the Results :) RonnieJ ps: E-mail me tell me how it went ok (RonnieJ, WildFire1) Thank you
