How to repair a USB stick on Ubuntu 20.04?

[mahesh]

Hi All,
The USB stick I used on my laptop, running Ubuntu 20.04, is no longer recognized after I copied some files on it from the hard drive. It does not show up when I stick it into the USB port and it also wasn't recognized on a Windows computer.

On another forum, I came across the following recommendation:

-try repairing the stick using ntfsfix in linux
and/or
-try repairing the stick using the ntfs filesystem of a Windows computer.

Do any of you have any experience with this?

Thanks
