What Are the Signs of a Failing USB Flash Drive

Typically, a pen drive will not instantly fail. There are a few telltale signs that can indicate if the thumb drive is about to fail. Ideally, you should get information off of the USB drive as soon as you notice any of these symptoms:

  • Randomly Disappearing File: One of the main signs of a damaged USB storage device is disappearing files. If you notice a file or two goes missing randomly, take it seriously, as the drive may be about to fail.
  • Slow Read and Write Speeds: While this could be an issue with your computer or USB port, sudden sluggishness in the read and write speeds of the USB drive could indicate imminent failure. Just to be safe, back up your data as soon as you notice this.
  • Computer Not Recognizing the USB Drive: If your computer displays messages such as “USB drive not recognized,” when you connect the USB drive, it could be a sign of a corrupted flash drive. Cheap USBs are more susceptible to random corruption.
  • Physically Damaged USB Drive: Needless to say, a bent or cracked USB drive will typically not work. Additionally, excessive use and overheating can damage the NAND chips on your thumb drive. Water-damaged USB drives are also quite common, and it’s dangerous to continue using them.

Why USB Flash Drives Stop Working Properly?

There are a few reasons why your USB drive may stop working properly. Knowing the exact cause of why pen drives malfunction is important because it helps narrow down the ideal way to fix damaged USB drives.

Here are a few common causes behind USB drive failure:

  • Incorrectly Removing the USB Drive: All of us are guilty of this. Suddenly removing a pen drive from your computer can cause logical or physical damage to the USB drive. Always use the Eject Media option on Windows and then gently remove the pen drive from your PC. Additionally, disconnecting the drive while it’s reading or writing data can result in data corruption.
  • Component Failure: Naturally, a USB drive consists of various electronic components such as microcontrollers, resistors, and capacitors. An unexpected power surge, short circuit or water can irreversibly damage them.
  • Excessive Use: All USB drives have a limited read-write expectancy. In typical usage scenarios, a USB drive will last many years and possibly a decade before it maxes out its read and write rating. However, with excessive use, it can fail earlier than anticipated.
  • Corrupted File System: Malware and improper usage (such as disconnecting the drive abruptly) can cause file system corruption, making your data inaccessible. Incorrect formatting is another reason for a corrupted file system. A corrupted file system comes under logical damage. In most cases, you can easily recover data from a corrupted USB drive.
  • Manufacturing Defects: Cheap USBs use low-quality components and will fail earlier than better quality ones. It’s always best to invest in a good quality USB drive (such as SanDisk or Lexar) from the beginning and save yourself the cost of data recovery when a cheap one fails.
  • Permanently Connected USB Drives: While it’s important to remove your USB drive correctly, it’s also important not to keep the drive connected to your PC permanently. The voltage fluctuations and other factors can result in overheating as well as significantly faster wear and tear of the components.

Can You Retrieve Data From a Broken USB Stick?

To perform a broken USB recovery, it’s imperative to know the cause of data loss. DIY recovery is possible in case of logical damage, accidental file deletion, and data corruption. Mild physical damage such as a bent USB flash drive can be bent back into shape.


The most important thing to realize, is that the pen drive should be readable by your PC. Even if it doesn’t appear in the File Explorer, it should be visible in the Device Manager, for data recovery software to do its work.
