Sender: drmadill@sunee.uwaterloo.edu Organization: University of Waterloo Date: Mon, 20 Aug 90 23:19:33 GMT Lines: 12 Has anyone tried formatting disksusing BIOS interrupt 13h function 05. I have been trying to use it, but so far, I have had no success. The drive spins and acts as though it is formatting but when I try to read or write a sector I get an error 4 returned in AH (which means Bad Sector: Requested sector not on diskette) If anyone could send me some code in C or assembler that works I would really appreciate it. Thanks David
