    When I boot my computer it comes up to the apple logo and has the loading wheel beneth it then after a minute or 2 a bar appears underneath the wheel. The bar stays for a while then leaves, it does this 3 times then the computer shuts down. I then proceeded to boot in single user mode to see if I could find the problem. Every thing boots fine until it tries to mount Disk0s2. It fails and says errno:19
    it tries about 7 times and then says mounted read-only. I then try to boot from single user mode. It then says Disk0s2 I/O error 3 times. and powers down. How do I fix this. I have no startup disk. :eek:

    Sounds like your hard drive is toast. Boot from your install DVD and run Disk Utility to see if you can repair the disk.

    He does not have a "startup disk" - best bet would be to buy a retail copy of Snow Leopard - but it does sound like that the hard disk is toast...

    What kind of Mac - MacBook or what ??

    Thanks, I missed that. Yes, a retail copy would work, and would probably be faster than ordering replacement install disks from Apple.

    I Finally got the system to mount by creating a new user through single user mode. I then proceed to use disk utillity to verifiy. It said the disk need to be repair, but not having a startup disk is frustrating. I then obtained a copy of DiskWarrior from my friend. I used it to repair the disk. It worked fine the first time I booted but then next time I tried it boot with the error loading drivers symbol (Circle with a slash through it). i tried diskwarrior again. but nothin
