I need help on choosing an external HDD. From Western Digital there is the My Book which is a larger drive which uses a power outlet and the My Passport drives which simply use a USB cable to the PC. I bought the My Book 1TB but i have also read reviews that say they crash and fail more frequently. i dont know if i should exchange this for a My Passport 320GB HDD. I dont want to have the 1TB and then watch it fail in a few months, if it does fail. The only thing i am considering is the reliability, should i exchange or stick with the 1TB. I will never fill up 1TB and the power outlet doesn't bother me at all. I dont plan on moving it around. If the Passport drives fail as often as the My books, i rather stick with the my book. I checked many sites with customer reviews but each gives different ratings. Some customers say its perfect some say it failed in however many days/weeks/ months. HDD's fail, but these seem to more than others. People with either drive give me your advice please. If you can provide personal experience feedback or a site with consistent customer reviews it would be great. So should i get the My Book 1TB or the My Passport 320GB?
