My Arduino board, powered by own 9V supply, collects data. I'd like to read out the data later. But when I connect Arduino to my PC via USB it reboots and all data is lost. How can I have access to the data if Arduino is not connected to PC all the time?

Data read out

Adafruit sells a data logging shield that saves your data to an SD card.
