Greetings again.
Well this is embarrassing... I have 50 GB left on my Time Machine backup disc, and I'm just trying to backup 4 GB of data using the usual plug-it-in-and-go Time Machine procedure.
The process gets stuck on some file somewhere, I have no idea what, it says Backing up: something like 1 GB out of 5 GB or so.
I canceled that backup, ejected the drive, disconnected it, plugged in both USB cables this time (one extra for power), and tried the backup again, and it gets stuck at 17 KB.
I've seen other people get around this somehow but a few times per year this happens to me and I have in the passed just wiped the disc clean and started over because it just sits there for hours.
What's going on? How do I force the backup disc to keep backing up?
Edit: Well......... it appeared to just fix itself a day later. I did run Disk Utility to verify the disk, and it repaired something. I'm not sure if that fixed it or just waiting longer did the trick. Whatever.
But for future reference, what's the troubleshooting process?
