    Greetings all,

    When powering up my G3 (yes I know it is a dinosaur), the grey screen with the apple logo appears, everything appears normally during the boot, then after checking settings, internet, printers, goes into Darwin/BSD console mode prompting a user name a password.

    After reading about similar problems on other forums, I booted in Single User mode, and ran fsck -fy. This is what appeared next on the next:

    ** /dev:rdisk0s6
    ** Root file system
    ** Checking HFS Plus volume.
    **Checking Extents Overflow file.
    **Checking Catalog file.
    disk0s6: I/O error.
    Invalid key length
    (4, 1327)
    **Volume check failed.
    localhost:/ root#

    Now I have no idea what to type in the prompt. I have read in other forums to boot from the installation disc, but I can not because I do not have one. Are there any alternatives to fixing this problem using fsck?

    Thanks in advance,

    Joe Wensell

    It looks like you have a bigger problem than can be solved with fsck or even a Mac OS X Install DVD. I/O error generally means something is wrong with your hard drive; recently my hard drive reported I/O error when bad sectors developed in the middle of my VM image (had to trash it :( ). Reformat and reinstall with secure erase (basically, zeroing every sector on the drive) should do the trick.

    I can't give you anything else; I don't know enough about your situation. Try holding "v" on startup to see if there are any error messages you can report.

    OK, how do I zero every sector on the drive?

    Also when starting the computer while holding "V" it brings back to the Darwin/BSD screen with the following message:

    IP Packet filtering initialized, divert enabled, rule-based forwarding enabled, default to accept, logging disabled
    IPv6 packet filtering initialized, default to accept, logging disabled
    IP Firewall loaded
