That's weird. I thought the volume serial number got changed each time a disk format was done, do I thought I could do the same without formatting.


>SetVolumeLabel() is as close as you can come. The API provides no functionality to directly set the serial number. In order to do so, you'd have to access a couple of ROM BIOS interrupt calls. Specifically, Int 21h Function 440Dh Minor Code 46h and 66h for FAT32. In order to do so, I think you'd have to write a virtual device driver in C.
