Last 2 crapped out and quit working as well. That's why I don't rely on flash drives to keep anything long term. I've had several of the fail on me. I haven't had a flash drive fail but it is common for them to fail at any time.
One of my favorites is the Corsair "Survivor". I've had mine for about a year now with no problems. However, I don't keep any critical data on it. A copy of its contents exists on my hard drive. PNY is not a good brand. One key thing is to ensure that your end-users understand that FLASH drives should never be used for mission critical functions, or where they are the only means of storing important data. Also, end-users need to be reminded that sensitive data needs to be kept safe, therefore unencrypted USB FLASH drives are not appropriate for that role.

NAND flash chips are somewhat unreliable in general. In SSDs manufacturers compensate for this by installing several chips and keeping the usable capacity lower than the real capacity. This way, when a chip starts to fail, the controller can move blocks elsewhere.
However, in small devices like USB dongles, this is usually not done, and sometimes not even possible space-wise. Thus, USB dongles fail. Use them to move stuff around, but never keep the only copy on any one device, and especially not just on USB dongle. Sign up to join this community.

To establish which is the problem, you'll need to know how to troubleshoot the USB port. This means testing the USB port. Start by connecting the device to another USB port. If it works, then the problem is the first port; if the device remains undetected, you have a faulty device. Note that if you can't reformat the USB drive , it will need replacing. If there's a problem with your USB port, you'll notice it thanks to either of these things:.
Either way, you should investigate the state of the USB port. Has it been damaged in any way? The safest way to find out is to shut down your PC or laptop.
Next, look at the USB port. Is it clean and dust free? There's a chance that dirt, dust, and general detritus might have become embedded in the port. This can happen with laptop and desktop computers alike. Dust will reduce airflow, causing your system to overheat. It is particularly damaging to laptops, where overheating can reduce performance in seconds. To fix this, clean out the USB port with a can of compressed air. If you feel a great deal of movement when you gently wiggle the USB connector, that indicates it may be bent or broken off the board.
And while it is sometimes possible to fix this type of problem, you're probably better off taking it to a professional. Try a different USB port. Many computers have more than one USB port, so a good way to rule out a single broken port is to unplug your USB device and try it in different ports.
Plug the USB device into a few of the ports on both the front and back of your computer. If the device doesn't work in any of the ports, there's likely a problem with its hardware. If your device starts working when plugged into different ports, then the first port probably has a physical problem that needs to be fixed. It's also possible that there's a connection problem with all of the USB ports on the front or the back, which is why it's important to try more than one on both sides.
Swap to a different USB cable. USB cable failures are more common than USB port failures, so make sure to swap in a different cable if you have one handy. If your device suddenly starts working, then you know that the problem was a broken wire inside the other cable. Plug your device into a different computer.
If you have another computer or laptop handy, then try plugging your USB device into it. This is an easy way to rule out a problem with the device itself. Try plugging in a different USB device. In this case, you may need to fix or replace the device that failed to connect.
Check the device manager Windows. There are two things you can do with the device manager in Windows to get USB ports working again. Scan for hardware changes by right-clicking the name of your computer, and then clicking on scan for hardware changes. When the scan to complete and then check your USB device to see if it works. Another option is to disable and re-enable the USB controller.
