format ?
what i am currently doing is ,open a file in binary mode then using either biosdisk or absread , write to the file .
biosdisk-i am reading 18 sectors at a time
absread -i am using a loop to read the 2880 sectors
everytime the image is created i use winimage to verify it and sofar no errors . i converted the image to 2.88 mb format using winimage and i saw two changes in the bootsector of 1.44 and 2.88 and some in the other sectors
