Mount SD through mbed?

I wondered if anyone knows if it is possible to have an SD card connected to an mbed mounted on my PC along with the built in 2MB of mbed storage?  I was just curious because I have a device that is built around an NXP2368 that stores data on a micro sd card, but when you connect the usb cable between the device and the pc the micro sd card gets mounted.

I currently have my mbed writing to my micro sd card, but I don't like that I have to pull it out of the mbed connected to my computer and put it in another reader connected to my computer to get data on/off it.

Thanks,

Matthew

What you'd be looking to do is use the LPC1768 USB (rather than the mbed interface USB) to come up as a MSD, and then give access to an SD card like that. I haven't seen any code pop up for MSD on the LPC1768 mbed yet, but I think there are various appnotes on the NXP site, and if you have it on the 2368 you are most of the way there!

Sorry for the confusion, but I have a product that I purchased that when connected to the computer mounts the SD as a MSD, so unfortunately I do not have the code for the LPC2368.

I did take a look around the NXP site, and I do see a few items about loading a different bootloader to allow it to show up as a MSD, which I am guessing I would need to do.  However I am not real sure how to proceed on that front.  It also looked like the code examples for this actually mounted the user code space in the chip as a MSD, so again unsure how to then present the SD as the memory space that gets mounted.

I think perhaps due to my limited knowledge on this I will have to leave it alone at the moment and just keep swaping the SD card around as needed.  That is unless anyone with a bit more knowledge wanted to take on the task and provide me some help!

Thanks,

Matthew
