Hi all, i'm using DeviceIoControl with VWIN32_DIOC_DOS_INT13 with VWIN32.VXD handle under win95 to read and write physical sectors from/to floppy (int 13h services 02h or 03h). I've write a cycle that read or write all the floppy track per track, first head 0 than head 1 for every track. This is the technique they said. Ok, in reading i have the same speed of dos diskcopy (about 36 seconds) but in writing (: is about 1 min and 10 sec. and diskcopy is about 36 or 37 seconds, same speed of reading ! I can't understand why this happen. Is possible that this virtual method to call int13h service 03 using VWIN32.VXD is so slow ? If some help, THX
