I just replaced my mac book pro's internal HD with a 160 gb WD passport drive. I took the old 80 GB out and put it back into the WD passport case to use as an external. I decided to format it as FAT 32 in hopes to use it as a large flash drive. But when I put video files on it, it takes forever to move them over. Reading from the drive isn't as bad, but writing to it is terrible. What kind of speeds should I be getting transferring files from the hard drive? Currently it takes a little over 1 hour to transfer 1 GB of data to the drive, and about half that to read from it. Is there something wrong?
