Sigh

Trying to get all my crap--- pardon me, the files of earth-shattering significance and undeniable galactic value-- off my MyBook and onto my new computer. Right now, it seems to be kind of... stuck. It's retrieved less than 3 GB so far, and now it's just staring blankly at me like it can't bear to go on. Come ON, computer, it can't be that hard to transfer info from one device to another. Can it?
