Hitachi HDS723020BLA642 2TB 64MB Cache

Well, I decided to pop the drive in after reading a bit more on the sata specifications. I did a hot swap, but there was no change other than a message telling me the drive in bay x was pulled out. So after putting the new one in (HDS723020BLA642) I just powered off and rebooted, then I got "UNKNOWN 465 GB" since I'm still using the 500gb drives. So far the light on that drive is still blinking green, so I'll let it go and see if it does anything eventually because it's not telling me anything else. It does say the drive is DEAD. I sure hope it works, I don't want to have to go back and return these because I don't know what else to get since I couldn't find the same ones I had. I need the space anyway.
