Data Recovery Tech Babble

Author : Jessica Moorhill

Data loss is as natural as a baby crying if you have a computer and use it for more than an hour a day. But thankfully the Gods who made the hard drives also thought of ways to get back data if you lose some. Here's how data recovery really works,
Hardware Recovery:
The hard drive, the storehouse of all your data, has numerous disks known as platters, which are coated with magnetic materials and spin at great speeds under an arm that moves backwards snd forwards over it. Your data, is essentially stored on the aforementioned platters.
After you've understood that you can figure out the cause of most hardware problems that your hard disk faces. Either the platters are having some problem spinning, or the arm (also called the head) is stuck. One of the ways to recognize this is the noise the hard disk makes when it fails. If you can't hear the soft spinning or hear 'clunk' - like sounds, turn off your PC and send your hard disk to a data recovery service.
Software Recovery:
As suggested by the name itself, data loss here occurs due to bugs/problems with your software. Data is written onto small sections of the platters called 'sectors'. For a large file, you'll use up more sectors in storing it, than you'd use in storing small files. When data gets deleted, what happens is that the concerned sector becomes open for the head to write over. That's why most data recovery professionals tell you to keep usage of your computer at a minimum when data loss has occurred.
Well, that's all you need to know to safeguard yourself against data loss! Let's hope you never have to call in a technician for data recovery!
