external hard drive went read only

I have a Seagate FreeAgent GoFlex Desk external hard drive, which i've loaded movies, pictures, videos, and documents on to. I have only used up about 100GB of 1.5TB and for some reason when I plugged it in today it wont let me load anything onto it and if you click get info on it, it says you can only read. Any idea what changed or how to fix this?

MacBook Pro, Mac OS X (10.6.3), 13"
