How important is UPS to save your hard drive
It is most people's worst computer nightmare. You wake up in the morning, you turn on the computer and it won't boot. Sometimes the problem rears its ugly head as a horrible snap. Other times it just gives a read error.
At this point, most people panic. The first thing you wonder is whether the data is recoverable or not. There is no universal answer to this. In some cases, a simple scan with some data recovery software is all that is needed to recover the contents of the drive. In other cases, if you want it bad enough, it will take thousands of dollars and a shipment of the disk to a clean lab where they will take the plates out of the disk and access them that way.
You are probably wondering if there is any way to prevent this from happening. Well, you're in luck. Getting a UPS (uninterruptible power supply) is the best and most effective way to prevent your data from disappearing.
flowing to your computer can reduce the risk of drive failure. This figure rises to around 90% if the computer is used during a thunderstorm. (My computer repair business always gets a little boost after a storm, courtesy of lightning strikes that wreak havoc on people's hard drives.)
Don't be left without UPS. You want to get a smart one. The "smart" UPS will regulate power without hitting the battery every time the voltage drops, greatly improving the longevity of the battery. They also include options to connect the power supply to your computer via a serial or USB port so you can monitor what the power is doing. This also provides the option to allow a soft shutdown if the power goes out and you are away from your desk.
You can obtain an uninterruptible power supply at most computer stores. Best Buy has a fairly wide selection of them.
In terms of brands, I have personally used APC with great success. Opti-UPS is another excellent brand. In fact, I have an Opti that is 6 years old and it still works fine, although the batteries are now dead. (That's to be expected. Rechargeable batteries only last a while)
Now that you know the importance of a UPS, I highly recommend that you invest in one. It is far better to spend $ 100 now on preventative maintenance than to have to spend much more later on data recovery.
