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 don't 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 can't delete a file. I can't move a file to the usb key. I can't do anything. This is really infuriating.. I don't 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"
