What can I do if I no longer have access to a USB stick?

The problem is that I have a USB stick that I can't access anymore.

When I connect it, although the laptop reacts to it and the workstation or now This PC is displayed as a removable disk but that's all, the update it loads for hours and is not moving forward.

I wanted to defragment it or optimize it but the program can't even open while the stick is tuned and video files can't play synonymous. Even with the laptop restart it is not progressing, but as soon as I take it off, it goes straight back to normal. Can anyone help me what I can do or what this may be?

First of all: USB sticks or SSD disks do not defragment. This does not need these storage media. Worse, they age faster.

You describe it as if the USB stick is simply broken. I do not think you'll get that part up and running again. I would format the stick and see if it goes then.

Reformat the stick, remove any partitions

Strangely, he goes to other laptops, how can that be?

Format the stick as FAT32. If the stick is larger than 32GB, you need this tool: https://www.sdcard.org/downloads/formatter/ This is actually for memory cards, but it also works with USB sticks.

If you put it in another laptop, then the USB stick goes and you have full access to it? Then that can only be an incompatibility. Just try all the USB ports on the PC.

It could be due to the power supply: If the stick draws more power than the USB socket provides due to a defect, such effects can occur. Some laptops, however, allow higher currents than the specification allows.

Yes, also a possible source of error.
