After reading all the reviews I decided to test everything as soon as I received it. Not a strict test by any means, just to make sure they're all initialized. Only two of them work in my case with front 3.0 ports. So I double checked to make sure they are initializing in Windows and there is nothing there at all, although the power light on the flash drive itself lights up. So I decided to test them on port 2.0. All 10 worked. So I tried 3.0 ports on a cheap 3.0 hub I have. All 10 worked. I have no idea why they don't work on the front ports of my cases. It's not a cheap case and I've never had a problem with anything else. I won't even deduct a star as I don't know what is actually causing this, although I'm pretty sure it's the discs. As cheap as they are, I wouldn't expect them to be the most durable devices out there. I only use it as an installer. If previous reviewers are really that worried about data loss, then why are they using ridiculously cheap flash drives and why, oh why, is this the only backup they use?
