He added, “Sometimes Windows asks me to format the drive, but I don’t want to format the drive as there are important videos and photos that I can’t afford to lose. I haven’t formatted the drive yet, please help!”. So here in this blog we gave all the possible solutions for this problem.

Here’s the solution,

A USB flash drive that is constantly giving this error while connected to a Windows PC via USB port can be both an annoying and worrying experience at the same time. Annoying since it’s constantly connecting and disconnecting; worrying as the data stored on the drive is inaccessible and if the problem is not solved quickly, it may lead to data loss.

The problem could be caused by software issues or hardware faults on either side – With the PC itself or else with the flash drive. Common factors that can lead to such issues are:

  1. Removal of USB flash drive without Ejecting
  2. Bad sectors
  3. Corrupt file
  4. Overheating of internal components
  5. Physical damage to the USB drive

How to solve this issue?

There are few probable solutions for USB flash drive recovery. Below we have discussed some quick fixes that you may try to repair your constantly connecting and disconnecting USB drive.

First, check if there is any physical damage to the USB drive. If possible, remove the outer cover and check if any USB connection to the board is broken. If everything looks good, proceed to the solutions we have mentioned below.

Solution 1. Try other USB ports and Systems

It’s quite possible that the USB drive is not getting ample amount of power or there is an issue with the USB port. Unplug and try other available ports. If the issue still persists, unplug it and plug it into a different PC. Check if you are able to access the drive.

This solution might seem odd but it did work for some people. Sometimes, it happens the issue lies within the system; however, it can be easily solved using this simple troubleshooting technique. Most importantly, if this solution works, take a backup and format the drive. Also, repair your Windows. If this doesn’t work, proceed to the next solution.

Solution 2. Use CHKDSK utility

The check disk (chkdsk) utility can help you find out the errors that reside on your USB or any other storage drive. The utility scans the storage drive for file system errors, bad sectors, etc. that makes the drive inaccessible and then tries to fix them simultaneously.

However, you can easily uninstall and reinstall the new USB drivers via Device Manager that fixes most issues including the one we are discussing in this post.
