I’ve been messing with my flash drives trying to follow some random documentation with dd and now both of my flash drives are reporting 0 bytes of free space. I was trying to clear out everything and start from scratch as if they were new. I wonder if there are any program out there that can just sudo reset-everything /dev/sdX
If you have GNOME just go into Gnomedisks select the drive and choose the format option. Or as somebody mentiomed Gparted is great but there are some things to learn for table, partitions, flags etc
