Knoppix can't delete files!
I basically have an old box here whose job it is to have images from weather stations FTP'd to it to be spliced together and then sent to our main web servers as .mov files. What has happened is that it has choked on the amount of old files it has collated and not deleted. The machine now refuses to boot as it says the disk is too full. I've booted from a Knoppix disk and changed the HDA1 permissions to R\W, but every time I try and delete the images it comes up with an 'Access Denied' error. The orgional OS was Ubuntu, and me not being very Linux minded am left scratching my head, as Knoppix won't let me change the file permissions. How can I delete these tens of thousands of JPGs from within Knoppix?
