I have an external usb drive that is not working properly:

When I try to mount it, or to do anything else, here the errors:

Any ideas to recover it? Thanks.

Either the external drive or your machine's USB hardware is faulty. Test the drive in another machine, if it behaves the same replace it.

It's also worth investigating the cable.

Some USB drives won't just work reliably on any old USB cable. This can be due to cable length, quality and sheilding issues. If the cable you are using was shipped with the drive, then yep it's probably a hardware problem. You also try on a different computer, maybe even running a different OS to eliminate issues with kernel version/device driver you are using.

Good Luck!

Had the same here, problem was that I used a power supply with not enough power. Voltage was ok but it could not deliver enough ampere.
