Glad to hear that the drive is working again. Could it be that simple? Not likely. At least, not based on what you've told us here. For example, if "straightening out the cord" fixed a poor connection, then the drive should not have mounted in the first place. If the drive mounted and played files, but would not transfer them... I really don't think straightening out the cord would do it. It's not a garden hose with a kink in it, after all.
When I was first learning to troubleshoot, a friend told me, "If a machine doesn't work at all, the problem is probably easy to fix. If the machine works, but not quite right, then it's going to be a difficult fix."
Again, glad to hear it's working again.
