In my experience with any Dell MD3000 we've had I've only had it certify one hard drive model as "certified" and compatible with my MD3000. This was a Samsung HD204UI 2TB hard drive. All others when placed in the MD3000 would show up as "uncertified" and instructed to remove the drive (tried barracuda and seagate). I've read around people saying you can buy pricey drives from Dell or try slightly less expensive resellers online.
Has anyone had experience with any other non-expensive 2TB drives with a Dell MD3000? I've only had one successful drive work and many other models and brands fail. I'd like to be able to run to Frys for emergencies and be able to pick up a drive if I need to.
