Summary: Failed after 1.5 years. I used it for about 10 times in 1.5 years, never dropped or spilled liquid on it. All of a sudden, I plugged it in and it could not stay connected to the computer for more than 2 minutes.
Summary: My impression after reading installation manual, was this must be easy. Just jack in the USB and the console will automatically detect the external HDD. Nothing happened. since the drive format is in NTFS. Back to the PC and reformat the drive to FAT and made a new folder labelled PS3.
Summary: I have only used twice. In both cases using the program that came with the HD, it worked fine. It is very fast and simple to use. I have been advised by a computer Guru to use the back-up that is part of Win 8.1. I will update later.
