So I can take out my 40GB original drive and simply put a bigger one in? Where is this documented?
Do a search on YouTube, there are several videos that show you how.
Also, the original is a 5400 RPM drive. I've read that's better for heat & noise.
Having said all of that. I have two external drives (750 GB and 320GB) plugged into a powered 8 port USB hub which is plugged into the PS3. Music, pics and (still in process) my DVDs are right there. NOTE - Externals need to be formatted in FAT32 rather than NFTS.
