Apart from such issues, a common and very irritating issue caused by USB flash drives is PC freezing, which lasts until you restart the PC. In the mean time, you face issues like missing file(s) or some part of the file(s) missing or corrupt.

As the lifetime of such a drive is about to end up, many of its flash memory chips fail, or vice-versa. In other words, the flash memory chips have their lifetime defined as the number of times they can be read and/write accessed. Pen Drives) are made of a number of integrated flash memory chips that have a specified period of their lifetime. However, you need use them carefully as they often lead to corruption of failure, thereby causing massive data loss. Well, these drives are quite useful though. In other words, you can store massive amounts of data on a USB drive or use it to create clone of your hard drive, which can be used as a portable copy of your computer. The USB drives are the prime sources of data storage as well as data portability. In contrast, if you remove such a drive forcibly (or pull out suddenly), either the drive or particular USB port may corrupt or fail. Once the drive is no longer in use, you may remove the USB drive safely to deactivate this channel. This channel remains active as long as the USB drive is connected to the computer. These USB ports establish a serial communication channel between both the computer and the drive plugged in. Well, the USB ports play quite significant role in data input as well as output, typically called as data transfer. In spite of the aforementioned input and output components, computers have multiple input/output ports one of such types is the USB ports. The machine utilizes a number of input and output components, such as keyboard and mouse as input, while monitor as output for these operations. You may also term a computer as a machine that processes data in one form and gives output in another form. A computer is an electronic device that takes certain types of data as its input and transforms it into another form of data or signal after multiple stages of data processing.
