I've had issues with my Samsung 840 Pro 256gb SSD for a while now. First of all I can't install windows 7 on it at all. It either stops during expanding files or doesn't even make it that far. At first I was told this was a ram issue or my disk drive, however both check out fine. I'm easily able to install it on my HDD and even clone it to my SSD but I want a fresh install not a clone. Samsung magician won't secure erase it because it says its in frozen state. I've tried the suggested method of unplugging it and plugging it back it...no go. I've tried using parted magic to sleep mode and awake to unfreeze the SSD...no go. I've RMA'd the SSD to Samsung and when I got it back still has the same issue. So I've come to the conclusion that its a bios issue. I have an ASUS M5A99X EVO R2.0. I'm assuming the bios remember the SSD and it doesn't matter which SSD I put in there it's gonna freeze again and again and again..... Is there ANY WAY to unfreeze this or fix to the bios so that it doesn't freeze the drives? I'm about to just stick with HDD cause this is ridiculous. Thanks
