My Passport drive falls asleep and will not wake up

Hi, I just purchased Western Digital WDMT5000TN 500GB My Passport Studio Portable Hard Drive for Mac. I am trying to us it for Time Machine back up. After running under Time Machine for an hour or two it falls asleep and will not wake up. I need to pull FireWire 800 connector out of my computer, (I get warning about unplugging drive without ejecting it first), and then plug it back and it works until next time.

Does anyone know how to fix this problem?

I use it with unibody MacBookPro Mac OSX 10.6.2. I use Firewire 800 connector.
