I back up all of my music to an external drive. My computer is an Acer running Win 7 that's not too old (about 2 years old). I previously had a WD external drive and it took forever even to copy one album over. I made the assumption it was the external HD and switched out to a Toshiba external HD. Same stinkin' problem. I bought a bunch of CD's today at a thrift store and I'm copying them to the computer. They rip super fast to the regular hard drive but it's taking on average 10-15 minutes to copy over to the external HD. Any thoughts? PS: I save nothing as mp3 files unless I download it as an mp3. Everything is saved as a wav file.
