Here is the online chat between me and Sony support:

Joe: Hi, my name is Joe. How may I help you?
mark: Joe, I want to partition the 60gb harddrive in half, instead of the 10gb for one OS, the rest for the other.
Joe: Please allow me to research that for you, I?ll be just a moment.
Joe: Thanks for your patience, Mark. At this time the, functionality to partition the harddrive is not available. Please feel free to check back with us in the future for possible updates.
mark: is that a standard answer or do you know if they are working on support this?
Joe: We have not received any information on this. It is possible that this feature may be available in the future. We just don't have information at this time.
mark: has anyone asked about this?
Joe: Yes, we have had others request information about this.
mark: ok, so will the PS3 OS be able to access external HD for game saves, movies, pics?
mark: You do know that the PS3 DOES support partioning of the internal HD?
Joe: Yes. Keep in mind that your movies and pictures must be in the appropriate format for the PS OS to recognize.
mark: what are the supported formats, and what is the required directory structure of the external hard drive?
Joe: The PLAYSTATION(R)3 computer entertainment system will support the following video formats.

- MPEG
- MPEG-2 PS
- MPEG-2 TS
- MPEG-4 (.MP4)
Joe: The PLAYSTATION(R)3 computer entertainment system will only support digital image files saved under the the following formats.

- JPEG (.JPG)
- GIF
- TIFF (.TIF)
- PNG
- BMP

mark: ok, what is the directory structure that I have to set up for folders and directories in the external hard drive or will the PS3 provide navigation window for me to point and choose the file I want (e.g. video file)
Joe: I will research that for you.
Joe: At this time, we have limited information on the directory structure for setting up folders for external harddrives. We can tell you that if the external harddrive is recognized by the PS3, you will be given a 'display all' option on the PS3 OS which will show all the information you will need.
