I took apart my iPod just now to change the battery, and now it's charging. Now, make me feel better. I could have sworn I put the HD back on correctly. I could have sworn I felt the connection "click", but do me a favor and make me feel better anyway: Would the dang thing even start if the HD wasn't connected? Am I worrying for nothing? It's not worth my taking it all back apart to check, y'know?
