USB drives have become the most popular storage solutions that secure your work documents, family photos, and other files. These small devices even carry bootable Operating Systems. However, like other technologies, they may cause issues at any time. Sometimes, flash drives act erratically and cause panic to users. Software glitches and natural deterioration may prevent you from accessing data in your flash drive.

Signs indicating trouble with your USB flash drive

Check for a few signs that your USB flash drive has issues.

Slow performance

It is frustrating when your flash drive takes a long time to transfer data. Even a small file transfer becomes time-consuming if the drive has issues. Bad blocks on your flash memory are the main factor that forces the controller to work more to find space.

Device not recognized-

You might have plugged in your flash drive, but your device could not acknowledge it. This problem occurs due to driver issues and corrupted partition tables. You may also find your drive in the Disk Utility or Device Manager without a valid file system.

Read and write errors-

In many cases, you encounter messages, such as ‘Data Error: Cannot Copy File’. It means that your safely stored files are now corrupted or unreadable. This is a sign of sector damage or memory chip failure. Your flash drive will not be able to read and write data properly. As a result, the stored information will experience integrity problems.

Sudden disconnections

Your drive often disconnects and reconnects when you are transferring files. You must be aware of the erratic behavior of the drive. The internal components of the drive and loss of connection affect the data. Each time the system disconnects, you have a risk of data corruption.
