A friend of mine who is leaving on a trip soon found a discarded (or lost?) 3rd gen 40 GB iPod. She brought it to me to see if there was any way I could get it working. Pressing any button causes it to turn on. The Apple logo shows up, then a picture of a folder and an exclamation mark, then it shuts off. I plugged it in to my MacBook via the USB iPod connector that came with my 5G video iPod. The same thing happens when I start it up; apple logo, folder with exclamation mark. Only after a brief moment, it pops up "OK to Disconnect" then quickly switches to a check mark and "Do not disconnect", holds that for a second, and shuts off. The hard drive spinning noise is not erratic, but it is louder than I remember my sister's 2G iPod being and notably louder than my nearly silent 5G. Any suggestions as to how to resurrect it?
