In springtime, people's fancies may turn to love, but their to-do list turns to cleaning. Make this the year that you finally recycle all the ancient MP3 players, toner cartridges, ethernet cables, and bulky monitors out of the closets, garages, and spare rooms where they've been lurking. Your home will feel more modern, and you'll be doing your part to boost the 27 percent electronics recycling rate. Just in time for another spring constant, Earth Day. Before you get rid of any of your electronics The first step on your recycling journey: Make sure that none of your personal data will be leaving the house along with your soon-to-be-discarded electronics. If you're using Apple's iTunes to manage your digital music and video, be sure you deauthorize any device you're recycling. "But that computer is dead" is no excuse: Apple expects you to simply deauthorize all your devices via the iTunes app, then reauthorize the ones that are still alive If you're recycling a smartphone, do a complete reset of your phone to wipe out its data and restore it to its factory settings. Before you do this, however, make sure that you've got your data backed up someplace else If you're recycling a computer or a hard drive, don't just assume that deleting files will wipe the data off your system, because it won't. All it does is reformat the space on the drive, and the data can be snagged using tools designed for disaster recovery. Now, on to recycling Broadly speaking, you have three recycling options: You can drop off your unwanted stuff in person somewhere; you can ship it away; or you can donate it to a willing organization. Drop it off in person. The advantage to dropping off your gear is that you don't need to really plan ahead and print out prepaid labels (as you would if you were shipping things away); you just toss your stuff in the car and go Another option that's cropping up across the U.S. is the electronics recyc

Why it's a good idea to own a USB-to-SATA adapter The USB-to-IDE/SATA adapter the most indispensable tool in my PC repair kit. Just this weekend, it once again proved itself worthy of that title. In a nutshell, the adapter allows you to connect an internal hard drive to your PC-externally. What would an internal drive be doing outside your desktop or laptop? Funny you should ask. About a week ago, my media-center PC starting displaying this message during boot-up: "Hard drive failure imminent." And you know what? It was. In short order, the machine wouldn't boot at all. Long story short, I had to replace the drive, reinstall Windows, etc. But I wondered if I could salvage any/all of my recorded TV shows. To find out, I connected the old, non-booting drive (now "naked" outside the system) to a USB port via my adapter. Huzzah! The machine was able to read the drive and copy over the recordings. Except for the hassles (and expense) of actually replacing the drive, no harm done. There's another reason to keep one of these adapters on hand, and that's if you're planning to upgrade to a solid-state drive (SSD). Unless you buy a kit that comes with an adapter, you'll need one so you can image (i.e. clone) your existing drive to the new SSD. Then you'll remove the old drive, install the new one, and presto, you're back in business. (Much faster business: SSDs rock.) Unless you have a pretty old desktop or laptop, you can skip buying a USB-to-IDE/SATA adapter and just go for USB-to-SATA. At the same time, I recommend one that supports USB 3.0. You may not need it now, but it's a good bet your next PC will have USB 3.0 ports -- and that'll make for much faster copying between drives. Trust me: When the time comes that you need to upgrade or replace a hard drive, you'll be glad to have a USB-to-SATA adapter on hand. By-The Xpert Crew @ http://techvedic.com
