Hello, I tried to backup gow3 from the disk to external in gaia manager but failed.

In gaia manager (has purple BG i think) it transferred about 16gb before aborting wtf, I looked at a list and it said it could be played externally. I would do internal but, I only have a 40gb ps3 so yeah.. While I'm here is their a more updated list of working games, specifically one that shows working external games for future reference, thanks.

Any help is appreciated.
