This is the first of a few articles that will highlight some of the tools/gadgets/gizmos that I find useful. I’m starting off with one that’s almost essential. External USB hard drive adapter. Recently, I’ve been looking for something a bit leaner than your typical usb -> hard drive converter. Yes, I’ve carried something like this for large (3.5″) hard drives to appointments. The idea is if you need to transfer data from an old pc to a new one, put the old drive in an external adapter and copy away.
