I found some info, lots of work but looks quite interesting. The data media must comply with SCSI commands, This will ensure similarities in reading data on various data media types: http://en.wikipedia.org/wiki/SCSI_command. I should modify my libs to this standard.
Some USB MSD (Mass Storage Device) class info: http://www.usb.org/developers/devclass_docs#approved Other info, such as an example on 18f4550 and C http://www.lvr.com/mass_storage.htm The use for this would be so I can plug my mp3 player into my PC to upload files to my HDD or SD Card. but yes, I saw someone had a SD Card bootloader. I had previously thought of this idea, but I am surprised that someone actually did it already. Thanks, Matt.
