Hey guys i know i have not been here in a long time but been moving around alot.

Can anyone spare some info on how to access a SD card RAW?

I am currently working on PIC microcontrollers and can read/write data to a SD Card but RAW. I was woundering how would i do the same on a PC.

I can use either:
VB6
VS.NET EXPRESS

Any links or examples would rock! thanks!
