When recovering lost data one must differentiate between several different types of data recovery processes. The reason for this is that basically some types of data recovery are far more difficult than others. For example, to recover lost data from flash drive storage all one needs to do is use a general purpose data recovery program to scan the relatively small size of that drive. The program will then create a list of recoverable files and allow you to preview or sort them.
Because a USB flash drive seldom exceeds 8 GB in size most data recovery programs can complete even a thorough scan of this device in just minutes. Furthermore we usually know exactly the type of file we are looking for when attempting to recover deleted files from a USB flash drive. These files are usually documents, photographs or other personal information that we manually placed onto the drive.
