USB drive is a portable storage device that can be connected directly into a computer using built-in connector. USB flash drives are also called as thumb drives, jump drives, key chain drives, and pocket drives etc. Sony, SanDisk and Kingston are the popular brands who manufacture USB drives. Flash memory is used in USB drive to store large number of files. USB drives are available in different storage capacities. The maximum storage capacity of USB drive is 256GB. USB drive operates just like any other removable storage device. When USB drive is connected into a USB connection, it will be shown just like any other removable storage device. Mac Operating System displays USB drive icon on the desktop whereas, Windows Operating System detects the flash drive and displays an Autoplay option to quickly access the files stored on USB drive. USB drive does not contain moving parts like hard drive thus they are less susceptible to mechanical failures.
Common scenarios that cause data loss are explained as follows:
- Accidental deletion of files from USB drive: When you delete files from USB drive or any other external storage device, they are not moved to Recycle Bin. Instead, they bypass the Recycle Bin. If you have accidentally deleted essential files from USB drive, then you cannot restore files from Recycle Bin because, the files that have been deleted from removable storage devices does not move to Recycle Bin instead they bypass the Recycle Bin resulting in loss of files. In order to restore such files you need relevant Recycle Bin Recovery Software.
- Data loss due to corruption: USB drive may get corrupted due to virus attacks. In order to remove virus, updated antivirus program needs to be used. But, sometimes antivirus programs can also cause data loss. When you connect USB drive, each folder and file is automatically scanned by antivirus program. If it finds any virus then it may delete entire folder which is affected by viruses resulting in loss of files.
- Abruptly removal of USB drives: Accidentally or abruptly removing USB drives from the computer may cause data loss. You need to use “Safely Remove Hardware” icon in order to properly disconnect USB drive from system. Because, even if you think that you have closed all the files on the USB drive, it is still possible that the USB drive is accessed by system in the background without any indication. Therefore, if you abruptly remove it from the system then it may corrupt the file system of USB drive resulting in loss of files.
- Data loss due to errors: When file system get corrupted, you may encounter error messages like “USB device not recognized” or “USB device attached to this computer has malfunctioned” etc. These error messages do not allow you to access files from USB drive resulting in loss of files. Generally, file system may get corrupted due to sudden power failure or abrupt system shut down while transferring files from USB drives to computer etc.
