Okay, first please forgive me if this is already discussed, but i've been searching the forum for half an hour already and can't find the answer i need.

The question is:
You know that when you connect your device to a PC through USB, the internal and external cards are shared as USB drives. Is it possible to share only one of the cards? I'm talking about the external one and i don't want the other one to be visible (even if it is read-only).

Thanks in advance.

If you have virtual memory turned on, you won't be able to share the internal drive.

I'm booting from the internal therefore can't create virtual memory on it

P.S. I forgot - the card is still shared anyway.

I'm booting from the internal, MMC2, and have virtual memory turned on.
I plug in the USB cable, and my N810 pops up a messsage that says:
Unable to connect via USB.
Memory card in use: internal memory card

I go to my PC, and two USB drives are listed.
I can access the first one, read, write, all good.
Accessing the second one gets me a message that says:
There is no disk in drive G.
Insert a disk and then try again.

Is that not what y'all are seeing?

This is, of course, if the N810 is on when I plug it in.
If I plug in the USB before booting the N810,
then I have full access to both cards and virtual memory is disabled.
I don't think you're going to beat that case,
because the drives are shared before the OS gets to them.

Bundyo, how have you got your internal card partitioned?

The N800 doesn't make the card available for USB unless it can unmount it (i.e. make it invisible for the N800) first, and it can't unmount if the card is in use. So, to keep one card mounted on the N800 and not available for the PC you could keep a file open. You could write an application, but the easiest would probably be to keep an .mp3 file or something on the card you want to "reserve" and start playing it just before you plug in the USB cable!
