I'm really upset by now, I've been trying 2hours straight to format a stupid usb drive (I'm new to ubuntu and I dont know if I will last long at this rate)

Basically this was the lubuntu boot usb key

I tried to remove files with sudo rm I tried to format disk with disk utility I tried to format disk with gparted (with unmounting beforehand)

NOTHING WORKS. I cant delete a file. I cant move a file to the usb key. I cant do anything. This is really infuriating.. I dont know what to do ?

here are some gparted errors while trying to format to fat32 after unmounting error fsyncing/closing/dev/sdb: input/output error input/output error during write on /dev/sdb

when I try to remove by hand, it says "read-only file"
