This may be the dumbest question ever asked in this forum, but your help would be appreciated. I did a search and did not come up with a clear answer. I have seen on XDA forums how to do a nandroid backup to the SD card (How to backup or recover via Nandroid - XDA-Developers). However, it states "Select Nand Backup or Nand + EXT Backup ifyou have partitioned your SD Card." How do I create this partition on my SD card? Thanks in advance.
