Part 1. How a Flash Drive Gets Damaged

You have to admit that, during the usage of your USB flash drive, you have faced all kinds of issues. Before we show how to perform a USB flash memory repair, you need to know that a flash drive can become damaged due to various factors, leading to errors such as:

• USB Device Not Recognized

This issue commonly occurs due to corrupt or outdated USB drivers, preventing the computer from identifying the flash drive. Power surges through the USB port can also damage the drive’s internal components, making it unreadable.

• Unknown Drive, Port Reset Failed

This problem may happen if the connection between the drive and the system is unstable, often due to a loose or faulty USB port. Hardware-level failures within the flash drive, such as memory chip malfunctions or controller corruption, can also lead to this error.

• Unknown Device, Descriptor Request Failed (Error Code 43)

Error code 43 typically occurs when the USB descriptor, which contains essential identification information, cannot be retrieved. This can result from faulty or outdated USB drivers, preventing proper communication between the flash drive and the system.

• The Device You Connected to This Computer Malfunctioned, and Windows Does Not Recognize It

Internal component failures, such as a broken controller chip or corrupted firmware, may cause this issue. Sudden disconnections during data transfer can lead to corruption, also making the device unreadable.

• One of the Devices Attached to This Computer Has Malfunctioned

Overheating is a common cause of flash drive failure, especially if the device is used extensively without adequate cooling. Physical damage from accidental drops, water exposure, or excessive bending can break internal connections, leading to device malfunction.
