My Essentials with wd smartware does not support the required AFP features

I am unable to find a firmware update for this drive to use time machine over a network connection to back up my macbook pro. I can not find any informaiton regarding this drive. Help is appreciated! 

Well for starters this is not a network drive and it comes formatted NTFS for Windows. Here is a link that may shed a little light on it  http://www.wdc.com/en/products/products.aspx?id=240

Looks like there is limited support for non NAS drives to update network featured and protocols from WD from digging through this forumn more. Just lucky time machine worked previously with the looser AFP protocal. There are Lion tweaks to work with the legacy drives. I would rather update the drive verus the latter.
