remove a directory that is busy?

[Bumpalot]

kubuntu 13.04
Am installing systemrescuecd on a usb stick to bootup using ext4 filesystem.
I copied the systemrescuecd files to isocdrom folder. Unfortunately I screwed up & used
sudo cp cd /mnt/isocdrom, instead of sudo cp cd -r /mnt/isocdrom.
How can I delete the contents of folder isocdrom, or delete folder completely?
Am not that familiar with coding, so sure would appreciate some expert help.

sudo rm -R /mnt/isocdrom

[Bumpalot]

Thanks for replying!
sudo rm -R /mnt/isocdrom did not work - read only file! Any other suggestionss??

[Snowhog]

Is the CD 'unmounted' -- removed?

[Bumpalot]

There is no CD. Folder contains all the files extracted from the iso file.

Try sudo chattr -iR /mnt/isocdrom followed by sudo rm -R /mnt/isocdrom

This is weird.

What's the output of

sudo ls -al /mnt

[Bumpalot]

bumpy@bumpyputer:~$ sudo ls -al /mnt

rm --recursive yyy

The -r in the command I suggested is the same thing as --recursive. I'm not sure why it didn't work before but did this time. And, uh, what is yyy?
