Hi, hopefully someone can help... I've got a hard drive taken from an Apple laptop and I'm trying to copy the files onto an external drive using Knoppix. I can browse the directory structure, but the documents folders on the drive say they're locked, and if I copy everything to the external drive, all the folders are empty. Is there any way to unlock the files using Knoppix? If not, what would it take to unlock them?

Thanks in advance.
