Xfer Speed slower than 1gig

Hey,

I got a gigabit LAN, with Cat6 between my PC, and the two 10/100/1000 switches, and to the WD My Book Live.

But when transfering files (Around 800GB worth, I am stuck at 15 Megabytes per second. On a Gigabit LAN I should be getting somewhere around 100 Megs. Is the hard drive buffer too low to accomodate anything faster?

If not, what else is the troblem, you think?

Rule this out first…
