If you're 100% sure disk 0 is the one you need to format/erase, you can use diskpart in an elevated command prompt to do that. Simply open a command prompt as an admin and type in "diskpart" to launch the command line utility. Diskpart is a utility included with Windows.
Next, type "list disk" to produce a list of disks. In this case, you seem sure disk 0 is your target disk, but it never hurts to double check before a format.
Type "select disk 0" and hit enter to select the disk.
Then type "clean", which will clear the current partition table on disk 0.
After the cleaning completes, assuming it does, type "Create partition primary" to create a new partition.
Then, type "format quick fs=[insert filesystem fat32, ntfs, or exfat here] label=[name of drive]" and hit enter.
After that, type "assign letter=[drive letter]" and ht enter. The drive should now show up in explorer with the label and letter you assigned.
