And when I say slow, I mean slow. A 1.05 GB file took 5 minutes to transfer, so we're talking about a transfer rate of ~3.5 MB/s. I'm using a 15" 2009 Macbook Pro running OS X 10.6.8. The external HD is a Western Digital Passport drive. From what I've read online, these speeds are typically reserved for USB 1.0. I have no idea why transfer would be so slow, but I'm hoping that someone on here might. Any help is very much appreciated. Edit: I just grabbed a flash drive and attempted the transfer to that. I'm getting about the same speed - Four minutes instead of five, but even so that's about 4.5 MB/s. Still not even in the neighborhood of what it should be.
