InCD CDRW seen as Read Only

[Muse]

I don't know what to make of this. I could reformat the CDRW, but isn't there another way to deal with this? I'm running Windows 2000 and the CDRW was formatted with InCD, a fairly recent version (Oct. 2004). I can't edit the names of files on the CDRW or create folders, etc. Happens in both my writing drives (CDRW and DVD-RW drives). Any suggestions appreciated!

Edit: A reboot did not resolve the problem.

Edit2: I guess maybe the disk isn't packet written. Maybe I didn't format it with InCD. Is there a way to tell if it is or isn't? Thanks.
