I'm running CM7 off an 8 GB SD card (using Ana Mardoll's excellent instructions Ana Mardoll's Ramblings: eReader: Running CM7 on a Nook Color from SD Card (REPOST)) and had a few SD partition questions. 1. The 4th partition is the largest, but Windows can only see the 1st (boot) partition. I'd like to load MP3's on the 4th partition, but I'm unsure how to go about doing that. 2. The 2nd and 3rd partitions are smaller, but are they also available for files? For context, I'm definitely a novice when it comes to technology - I'm slightly amazed I got my Nook rooted! Thanks!
