358 Part III . Choosing and Installing a Linux Distribution (which is stored in that directory and in /etc files). The problem is that those directories are in RAM, so they disappear when you reboot. The following sections give you some ideas about how to save what you do in your KNOPPIX session to use in future sessions. Writing to Hard Disk Although hard disk partitions are mounted read-only by default, you can make them read/write if you like. Then you can store any data you want to save on those partitions. (You can simply drag and drop files to those partitions.) Up to this point, there s not much risk of damaging any data on your hard disk. Once you make your disks writable, you have the potential for deleting or changing that data. Keep that in mind if the computer doesn t belong to you or if you are not used to using Linux. Regardless of which user you are logged in as, KNOPPIX does not prevent you from changing any file in a writable hard disk partition. Mounting Linux Partitions for Writing KNOPPIX usually identifies all hard disk partitions and adds entries for each one in your /etc/fstab file. If you click the icon representing that partition, the partition is automatically mounted and a folder opens to the root of that directory. The name of each partition (hda1, hda2, and so forth for IDE partitions; sda1, sda2, and so on for SCSI disk partitions) is shown on the desktop icon representing each partition. Hover the mouse pointer over the icon to see information about the partition s mount point and device name. With that information, you can make any of those partitions writable by following these steps: 1. Click the hard disk partition you want to write to on the KNOPPIX desktop. A folder opens, displaying the top directory in that partition. 2. When you know which partition you want to write to, close all folders or shells that have that partition open. (With the partition open, you can t remount it.) 3. Open a Terminal from the panel and, using the sudo utility, become root user by typing the following: $ cd $ sudo su - # 4. Make sure that the partition you want to mount as writable is unmounted. For example, to unmount the second IDE hard disk partition (hda2), type the following: # umount /dev/hda2 Caution
