My time machine backup disc comes up with error:
Files can’t be copied onto the backup disk because it appears to be read-only.
Disc utility can't fix it and gives me the following message:
Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
How do I reformat that drive?
iMac, Mac OS X (10.7.3)
Use the Erase option in the Disk Utility.

Thanks for reply, Niel. I tried to erase and it wouldn't let me. I'm doing it again right now, so that I can capture the fault message. I'll get back with it when it comes up.
Tried to erase and came up with these messages.
OK. Lets try that again.
"Mac OS X can’t repair the disk “Time Machine.
You can still open or copy files on the disk, but you can’t save changes to files on the disk. Back up the disk and reformat it as soon as you can."
Also
"Disc erase failed
Disk Erase failed with the error:
Couldn’t unmount disk."
Thanks for your patience
