Ubuntu Servers :: Lost Space After Cloning (Samba / Windows XP)

I recently installed Ubuntu Server 10.04.2 and configured it to be used as a network storage device. I installed it on an 80GB HDD initially. Everything was fine -- I could read and write to the drive and I could set permissions from my Windows XP machine.I decided I wanted a bigger HDD. It had taken a few hours of configuration to get it to work the first time, so I didn't want to go through that again. I instead created a clone with Clonezilla and then slapped the image onto a 1.5TB drive. I then used gparted to resize the partitions.

Everything seems fine from the server side of things (I'm fairly new to it, so I could be missing something, but it all looks good). The server correctly sees that I am using 2-3GB of the 1.5TB drive. It sees the rest of the space as free and part of the primary partition.Here comes the problem -- Windows isn't reading the drive space correctly. It sees that 80GB of the space is taken (the size of the original HDD) instead of 2-3GB. I'm not sure if it will actually let me write to the space or not. But whether the reading is simply cosmetic or if Windows really thinks it's taken, I would like to fix it either way.
