remove time machine backup from disk

Hi I just set up a new larger external hard drive for my time machine backup. I would still like to use the former disk for other storage. How do I remove this from the time machine setting and properly erase the disk? I tried removing the disk and erasing under disk utility but came up with an error message, likely the time machine formatting restricting this in a safety feature. Thank you in advance for any help fixing this.

hmmm...

if no resolve see about removing the old or re-select your current BU drive...

not sure if you can delete from the list..

see this reference:

"Remove a backup disk: Click the Remove button , then ..."

I would be sure to first disable Time Machine. Then you should be able to use Disk Utility to reformat the disk. I have done this myself.
