There are plenty ways to lose data from any storage device whether it's a hard drive, RAID, solid state drive (SSD), flash drive or a memory card of your photo camera. Any device can experience failure, human errors (like accidentally pressed "Delete" button), software corruption or even natural disasters. A smart phone or USB drive can easily be dropped into water; you can spill coffee on your laptop or drop an external hard drive. What's next? In most cases, data on the device or media is not lost irrevocably, it can be retrieved. What is data recovery? It is the process of getting the data from a failed storage device. In most cases, it needs special skills and experience, complicated equipment and peculiar conditions - not every person who is aware in the technics is able to recover data.
