Share memory access on SD card between a PC and an Android App When you connect an Android Phone with an SD Flash card to a PC, with the Disk Drive option selected, it temporarily will be impossible to access the flash from the an Android App. What about phones with internal Flash?

I am looking for a way to share memory between an android phone and a pc.
There is apparently an app in the Market that does this.  I do not know the name.  It probably requires root.

However, doing so is a terrible idea.  Two operating systems should NEVER access the same disk at the same time, because they do not know about each other's writes.  If you do this you will lose data, possibly everything on your card.  There is no advantage to this anyways unless you are doing something extremely bizarre.
