Let me start by saying I am not the most tech savvy on this site. I just added the leaked 2.1 yesterday and was trying to add the new 2.1 music player that a few people have added. I dl'ed it on my computer and connected my eris to my PC through USB. Once I connected, it gave me three options, charge only, HTC Sync, or disk drive. I chose disk drive and added the new musicplayer file to my phone. Forgetting how to access my SD card files, I went to Settings>SD card &phone storage> and quite regretably hit Unmount SD card. In doing this, the only option I have on that screen is to Format (erase) my SD card (Which I'd rather not do). Now when I connect using USB, I only get the first 2 options, charge and HTC sync, and cannot connect with my PC anymore as a disk drive. Does anyone know how I can connect back up with USB to my computer? and where do I go to access the files I've added to my SD card? Thanks in advance!
