Pulled a drive out of an old Mac Laptop, wasn't mine so I don't remember what model. It was more than 5 years old. When I boot Knoppix, fdisk recognizes that there's a hard drive, but it says that it's not set for 1024 so there could be a problem. What do I need to do to get Knoppix to recognize the drive so I can pull stuff off of it?
