hey,
I need some inputs in creating a "virtual hardware" FDD drive using some SD card and a PIC micro controller.I have a PIC18f4550 with me and i know it has sufficient RAM for the SD interface? then how do I confuse the windows to have a FDD present in its hardware.. 1.44 MiB is enough for me. any help?
 


It appears you want to create a PIC based SD Card Reader/Writer with USB interface:

Some examples:



SD Memory Card Interface - Strictly Serial Interface Nonbootable

Implementing FAT on CompactFlash cards, SD/MMC cards and USB sticks

You will have to implement a FAT File System Read capability with the PIC, a SPI interface with the SD card and the appropriate USB interface for the PC to be able to boot successfully.

You will most likely have to settle for a larger "floppy" size 256MB, 512MB or larger. Unless you want to create a smaller partition.

The first example is a fairly good example of a PIC based bootable SD card reader.
