1. Damaged USB connectors: Flash drives have a sensitive USB connector that can harshly break off when inserted or disconnected from a computer. It could tend to break or bend, leading to data loss.
2. NAND chips fall off PCB: Nand chip on a flash drive is located at the surface of mount technology which gets corrupted easily. In addition, these chips are vulnerable to overheating and also affects the printed circuit board failing the USB drive.
3. Malfunctioning components: The mechanism of flash drives works only because of the tiny components inside it that can fail anytime when not taken care of. Components like microcontroller, capacitor and oscillator resistor can burn out and lead to failure of the flash drive.
4. Files system crash: While transferring data, if some damage occurs, the files system can get corrupted by the flash drive. This interruption in the transferring process can also put your data at high risk by losing or corrupting it.
