I bought this hard drive just 3 days ago to update my PS3's 40GB internal hard drive. the whole process was perfect, the hard drive itself arrived within 3 days and as soon as i had it after backing up everything from my 40GB hard drive onto an external hard drive (Must format to FAT32) i moved straight onto putting in the new one. putting in the new one is easy enough to do, you just have to look online to find out how to do it. once in you must restart your PS3 a few times for it to accept the new HDD and when it does it begins to format the hard drive which right away loses 22GB but has to be done. Once formated you must use your external hard drive and save the newest PS3 update to it (V3.70)and update the PS3 from the hard drive. once all that is done and you add your information to the PS3 you are finished pretty much. Just go into System Software > Backup Data Utility > Restore from Backup and once you restore from your internal hard drive (shouldnt take more than 40-50 mins on a previous full hard drive)you have your old PS3 back, but with a LOT more memory.
