Can’t copy anything to the drive…!!! (SanDisk Cruzer Blade USB Flash Drive - 32 GB - USB 2.0 )

I am having the same issue but I am on a Mac OS High Sierra version 10.13.6

I don’t know how to reformat this drive… What should or can I do?

Do I need to continually buy additional drives?

In advance, Thanks for the advice!
