eMac - Can't find Macintosh HD after running Volume Repair from Tech Tool

I have an eMac. I noticed it's been running extremely slow, so I booted from Tech Tool and ran a scan. I ran the Volume repair and now I can't reboot. When I try, it shows a white screen and a grey apple, then it turns all grey with the power button icon with a message telling me that I need to restart.

I used the OS X installer disk to boot and when I go to disk utility, Macintosh HD is greyed out and I can't point to it to reinstall the OS.

I also ran Surface Scan using Tech Tool and that came up clean.

Help...

Mac Mini, Mac OS X (10.4.7)

are you using the correct operating system disk, the one for the 10.4 operating system??

you could try using fsck instead. take any note of error messages. see the "use fsck" section of this article. http://docs.info.apple.com/article.html?artnum=106214

hopefully the tech tool didn't ruin your hard drive. another thing you can try is doing a pmu reset. directions are in part 6 of this article. http://docs.info.apple.com/article.html?artnum=34885 if your emac is an ati graphics or later, the reset button is on the right side instead. once in awhile it will make the hard drive available again for repair. best of luck.

What version of OS X is on the eMac? (Your profile shows 10.4.7 but for a Mac Mini.) What version of Tech Tool did you use? An older disk utility can potentially cause serious problems with a 10.4.x HD; see Only use Mac OS X 10.4-compatible disk utilities with Mac OS X 10.4 volumes.

Similarly, what version OS X Install DVD did you use to see if you could run Repair Disk from Disk Utility while booted from the OS X Install disc? Is it the OS X Install disc that came with the eMac? If the eMac has been upgraded to 10.4.x, did you try the Tiger Install disc you used to upgrade to 10.4?
