Most people would agree that to understand how data loss occurs and how data recovery [link widoczny dla zalogowanych] professionals work, it is imperative to know the hard disk itself. So here goes,
The hard drive is basically a mechanical instrument with a number of moving parts. One of them being the platter. Several platters exist in a single drive and [link widoczny dla zalogowanych] are covered with magnetic materials. These platters are used to store your data with a mechanical read/write arm, or the head, moving across them to retrieve your data or to write new data. The arm, [link widoczny dla zalogowanych] in turn, moves with the help of an actuator.
One of the most important things [link widoczny dla zalogowanych] to know about hard drives is [link widoczny dla zalogowanych] that [link widoczny dla zalogowanych] the head hovers just millimeters above the platters so if it's disturbed by the smallest of substances, you can kiss your data goodbye.
Now, moving on to how data loss occurs. In [link widoczny dla zalogowanych] the case that you [link widoczny dla zalogowanych] lose data due to hardware problems, what's really happening is that either your platters aren't spinning or the head is stuck. Both ways, there's a [link widoczny dla zalogowanych] high risk that you'll be losing a considerable amount of data. So, if you figure there's a problem with the hardware, switch it off and take it to a data recovery service ASAP!
When software related issues lead to your data [link widoczny dla zalogowanych] being lost, there isn't any need to panic because chances are that you'll recover most of it if you don't use your drive after you've lost the data. [link widoczny dla zalogowanych] This is because the data that is deleted remains on the platters unless it's overwritten by the head. Pressing delete makes the particular sector open [link widoczny dla zalogowanych] for overwriting so if you don't use the drive, data recovery professionals can recover the data loss easily.
