I seem to be going round in circles here, but in order to run a file system check on my HD, I assume I need to booted from CD so I can unmount the HD. I have OS X 10.3 disks. So can I boot from those and get into Terminal to run the file system check? If I boot with disk 1 in and with Option pressed, I get options to install or boot from the HD. If I boot with the grey disk, I get Install, boot from HD or AHT. Do I need to create a boot CD? Help! Cheers!
