After I contacted the support of SCE via email and was told that the installation of a 750GB hard drive is possible without problems, I decided to buy the Seagate hard drive. The installation work is relatively easy (this end up doing more). The hard drive is much quieter than the "old". Now back to the hard disk installation (PS3 model "FAT" former 80GB.) - It is necessary to remove the cover on the side, here the holder in which the 2.5-inch hard drive is attached with a blue screw, turn it easy to get out and Pull out the cover. The hard drive is also mounted with 4 screws on the cover, this is removed. Also and sets purely the new hard drive, pushes it back to the Playstation and fastened it back with the blue screw The cover and you're done - but only part. 1 Now when you start an error message indicating that the hard drive does not have the system software. Now you should be on [...] go down and right the current system software draw on a USB stick (FAT32). When the download has worked have to stick to easily connect to one of the USB ports of the PS3 and press Start and Select simultaneously. Now the next steps are easily explained and the hard disk is formatted and installed. If you have previously made about the backup utility the Playstation 3 a backup on an external hard drive can be produced via the selbige the data again. That worked for me (there were almost 65 GB) lasted almost 3 hours.
