My application required them to be disconnected and 3 out of 5 failed. One of the ones that didn't work, I did a hard drive repair and 1 out of 3 was restored. I copied some large files to the drive and it seemed to work fine; When I tried to create a boot disk with another operating system on it, these problems started appearing. All in all too much hassle and I'm sending the batch back. I've had several "famous brands" and they've worked great. It's just not worth saving a few bucks.
