Tablets are the hottest gadgets for consumers who want information and media at their fingertips. Be it iPads, Androids, or Windows Tablets–if you're wondering how to sort through all the options, our tablet guide will help you navigate the tablet world.
Amazon, for example, offers a huge selection of tablets to choose from. Whether you're replacing an e-reader with something more flexible, or you just want to be able to look up where you've seen that actor before while watching your favorite TV show, our tablet buyer's guide will help you pick out the perfect tablet just for you
Which Operating System and Size is Right for You?
The first step in this tablet buying guide–and the biggest decision you have to make–is which operating system you prefer. Do you want the simplicity of Apple's iOS, the customizability of Google's Android, or a Windows 8 tablet that will run most of the same apps as your computer?
Do You Want More Storage or Less?
While you may think that bigger is better, if you're primarily using your tablet to read books or browse the web, you may not need a ton of storage. Movies, TV shows, and music can all be streamed directly from the cloud to your tablet instead of storing them locally too. If your tablet will be connected to the internet via Wi-Fi most of the time, you can save a lot of money by getting a tablet with less storage.
Stay Connected Everywhere
Adding 4G connectivity to a tablet will increase its price significantly, and you'll also need to pay for a monthly data plan. Overall, it's the most expensive decision in this tablet guide. You'll want 4G connectivity if you're going to spend a lot of time out and about (away from Wi-Fi) and want to check your email or browse the internet on your tablet. AT&T and Verizon offer plans that share the same data pool as your smartphone, and Amazon offers an incredibly cheap data plan when you buy a Kindle Fire HD 8.9" 4G LTE Wireless Tablet.
How to Make Your Final Decision
So here's your tablet buying guide ideal strategy: First, pick out which operating system you want. If you want something easy to use, go for an iPad or a Kindle Fire HD. But if you want to customize it so it's just right for you, go for an Android tablet like the Samsung Galaxy Tab 2. If you want to primarily get work done on your device, pick up a Windows tablet. Next, decide whether you want a portable, small tablet or more screen space for typing and watching movies. Finally, decide how much storage you think you'll need and whether you'll want 4G data to go with that. Any time you feel unsure, you can always come back and check this tablet guide for handy reference. Happy shopping!
If you are ever in a situation where your hard drive is about to fail, the first thing you should do is make a clone of the failing drive ASAP. The quickest (and arguably the easiest) way to do this is within your favorite Linux instance without having to install any fancy tools. When you clone a failing drive, you literally copy that drive byte for byte onto another drive. Once cloned over to the new drive, you can then access your files freely.
But what if your drive has already failed? Same technique. Just because you can't access the files within Finder (in Mac) or File Explorer (in Windows), doesn't mean the files are not there. You would clone the drive the same way and copy everything over byte for byte onto a new drive. If all goes well, you should now be able to access those files from the new drive.
The technique below walks you though cloning a drive within Linux using dd command to clone the drive. dd is a powerful UNIX utility, which is used by the Linux kernel makefiles to clone data, among other things. Only superuser can execute dd command, but that is as simple as adding sudo to the command line functions.
WARNING: While executing dd commands, if you are not careful and do not know what you are doing, you WILL lose your data.
To clone an entire copy of a hard disk to another hard disk connected to the same system, execute the dd command as shown below. In this dd command example, the device name of the source hard disk is /dev/hdsource, and device name of the target hard disk is /dev/hdtarget.
# dd if=/dev/hdsource of=/dev/hdtarget
