Just rec'd rasp pi and it came with a loaded sd card. I am having problems with the composite video and was suggested I edit a file on the first partition. When I looked for the file it was not there. I was able to read the dir in win 7 explorer. I was trying to access the second partition, which I never figured out how, all of sudden it cannot read any of the disk and tells me it needs formatted. I backed up the visible partition. If I format it, will it blow up the invisible partition and just format the the 1st partition. These fresh out of the box systems are confusing...I reseated several times and it started to read again.
Here's a screenshot of the dir.
