I have lot of important data on this hard disk. For experimental purpose I want to build a new kernel image from a source which will contain modified code for file system implementation (the code contains some modifications to ext2 implementation). Also it may contain lot of bugs which may corrupt data on the disk. So, after loading the new linux kernel image, I want to make sure that my old data stored on the disk must be safe. In order to achieve this, I want to create a new partition on the disk. After loading the system with new kernel image, I want to access only the new partition that I created. And I want to hide the old ext2 partitions. Now the problem is how can I hide the old partitions after booting the system with new kernel image (to avoid corruption of my old data on disk ) ?? Any configuration is needed to hide file systems ?? Can anybody help me how to solve this problem ??
