I don't know how to defrag a disk (you rarely need to anyway), but the following would work, for checking as well. Either boot up the system in `single' or `emergency' mode (at the LILO prompt, "linux single" or "linux emergency"). emergency in particular will mount the root read-only and enter single user mode. (I think single will mount all file systems read-write, and still enter single user mode.) Or you can shutdown the running system to single user mode; "shutdown -h now" will get you to single user mode. Then unmount partitions, and remount the root read only with mount -o remount,ro -n / To get the system back to multiuser, you can either reboot, or remount everything read/write and exit the single user shell. (I think the system goes back to multiuser in this situation). If you forget to remount as read write, it'll enter multiuser mode with the disk read/only, and you won't like that.
