Memorex USB 8GB drive that shows 0 B available. I don't know if it's mechanically broken or something is wrong with it.
Even disk part shows it as (See Disk 2)

Unless the data is very valueable (insert 4-5 figure number here) - then you can ask one of the specialist data recovery centers - you can only throw the stick away and get a new one.
The "No Media" would bother me. Is it showing up in the Device Manager? Disk Manger? How old is it?

Then create and format it again.
