floppy file permission problem

I've combed the prior posts for an answer but cannot seem to find one that fits.
I have a half dozen imation super disks, 120 mb. I would really like to use them occasionally.
I can't seem to format them to ext because of a permission issue. But I somehow think it is not a user permission problem but a disk issue.
I have already done:

Code:

chown root:floppy /dev/fd0 && chmod 660 /dev/fd0 && adduser <username> floppy

checked to see that I was properly added as an user but when I tried:

Code:

mke2fs /dev/fd0

I get:
mke2fs 1.41.11 (14-Mar-2010)
/dev/fd0: Read-only file system while setting up superblock

This has me going around in circles for 2 days now.
Any suggestions?

I think it is locked by software. There was a way to hack it I think, but it may have been for encryption.

This is particularly annoying because it seems to be the same problem that kept me busy for a few days trying to set up a boot disk from a USB San-Disk plug-in.
