"The automatic crappy software is the problem."1.5 starson by techman93
Pros: Portability and size. Decent performance.
Cons: Software causes this to have all kinds of read errors do not even attempt to use their pre-format. You will lose your data if you do not format before copying.
Summary: Best to format before even starting to use this HD. I am very weary about it even working. But so far it has been good surprisingly since I did format it. However when I tried to format it in windows7 it BOD lol. I did it on an xp laptop and it worked then delayed BOD. Whatever software that comes pre-installed is the worst software I have ever seen. FORMAT BEFORE USING! You are warned!
