When creating a clone of your ext4 file system in order to host RetroPie from USB, is it best to use DD to create an image first, then write it to your USB; lastly expanding the file system with resize2fs, or is it OK to use the copy and paste features within Gparted, and use it to resize the file system?
I ask because I keep getting file system errors every since I installed this new 250Gb USB Sata external HD.
