Thanks for the info. There's actually mention of NTFS-3G on the harddrive. I may try that....will see if I can find out further info. The HDD documentation is a bit on the light side. Also, oddly I was able to load a video onto the NTFT HDD and actually see it on the PS3, click play etc...but then the next one I loaded disappeared and then both video's and folder disappeared on the HDD.
