4.5 Samsung HDD Upgrade Bert1965 | 11/04/2013 | See all Bert1965's reviews (1) Great little hard drive with BIG storage and prompt delivery. This was the easiest upgrade I have ever completed. Just back up to an external drive (fat32 format) replace the hdd and re-install the back up, easy peasy. The storage will show at just under 600gb because of file allocation issues. However 40gb to 600 gb is an impressive and cost effective upgrade. Do it !!
