Flash drives or USB drives can be called as one of the most portable storage devices being used today. The variety of USB drive makers, and the wide range of storage capacities in which this device is available, has made it extremely popular among many users, since users have the freedom of choosing from this wide range, the flash drive that suits them the best. They are highly robust in nature, since the user can rewrite data over a million times on this device. Though the initial capacity in which these devices were available, was limited to 256 MB, over the years this has changed, considerably, and USB drives nowadays can hold up to 256 GB of data.
These USB drives are used for storing various types of data like documents, photos, music files, videos etc. The user also has the option of running the operating system using a USB drive. Since the flash drive comes with a USB interface, it can be easily plugged into the USB slot provided on the users PC, or any other device that provides a USB slot. The absence of moving parts makes transfer of data easier and quicker in this device. Since moving parts are missing in this device, physical damage to the flash drive can happen only if the USB drive is mishandled.
Logical damage can however occur in a variety of ways. There are of course the usual reasons of data loss like accidental deletion of files by the user, loss of files after the user accidentally formats the flash drive etc. But, one of the main ways in which data is lost in a USB drive is due to improper plugging and removal of the flash drive from the computer. Since the flash drive is a plug and play device, the user can simply plug the device, and transfer data from the device to the PC or vice versa.
However, the problem occurs when the user pulls out the device, without disconnecting it properly, or when there is a power outage during transfer of files. In scenarios like this, there are chances of the files being transferred or files those are already existent on the device getting deleted or lost. When such a thing happens, the first thing to do is to stop using the device immediately and download a good USB recovery tool that can recover data from flash drive. Downloading a software that provides a demo version would be of great help, as you get a chance to evaluate the software before buying it.
