Physical/portable Hard drive tester/diagnostics tool [closed]

Are there any tools that I can plug into a hard drive and perform diagnostics such as displaying if there are SMART errors? I work with a lot of commodity hardware and need to check if some of the disks laying around are good. It's a pain to put them in a computer. boot up Unix or some proprietary recovery software, and check each drive individually. It would be awesome if there was a device that I could plug in, and after a reasonably short time, give a status code or something. Ideally this would work with both IDE and SATA interfaces.

For this sort of work (and more) I've invested in a "universal" drive adapter, which is a set up plugs and a power supply that allows me to connect both SATA and PATA 2.5" and 3.5" drives via a USB cable. Mine's an older version of this one.

All the major manufaturers (Seagte, Fujitsu, WD) offer testing apps. I would invest in a cheap ($15) drive caddy. They attach via USB and drives are inserted like bread into a toaster. No opening the case, cables to deal with, etc. They do only come SATA or IDE though, so you would need two.

You can use the vendor tools I mentioned or smartctl and you'll have more information about the drives than you ever wanted!
