On my AT&T PC 6300, I ran a short simple test to determine the effectiveness of using a QD/DS disk in the disk drive. Here is what happened: 1) I used a DD/DS disk with several files on it (all non-hidden). 2) I copied it onto a QD/DS disk with MS-DOS "COPY" 3) I copied it onto a QD/DS disk with Central Point Software's "Copy-II-PC" When I added all the numbers up of the files and bytes free on the disk (using UNIX's "bs"), I made an interesting discovery! Look! ----------- QD/DS ------------------- Disk #1 (DD/DS) Disk #2 (Copy) Disk #3 (CopyIIpc) 145418 bytes 332406 bytes 145418 bytes Something MUST be wrong, because the disks are supposed to have 360K in MS-DOS version 2.11. All of the disks, by the way, were pre-formatted, one after the other, and all three were said to contain 362496 bytes. What's wrong? hou2e!ksl
