I have an old USB I plugged into my computer, but it doesn't show up in file explorer. I tried running CHKDSK on it but it said Cannot open volume for direct access. I tried using FORMAT but it also said Cannot open volume for direct access. When I run Disk Manager, though, the USB doesn't come up under volumes, but it appears as a Disk. I also tried changing the letter assigned to it (in Disk Manager), but it didn't do anything. How can I fix it?

PS - I know that the USB is connected because the light on it lights up. I also know that disk in Disk Manager is the USB, because it disappears when I unplug the USB.

    The data is sufficient to confidently say it failed completely. Replace it.

    Yes, but it shows "no media". It means the actual flash memory is fried and what the the system "sees" is only the USB controller.

Your USB Drive is broken and needs to be replaced.

A USB Drive has 2 parts. It has the ram chips that store data, and it has the controller. It seems either the controller is malfunctioning partially and it can't access the data chips, a trace between the ram chips and controller is severed or the data chip(s) is/are broken and the controller gets no volumes that way.

Either means: replace the USB drive.
