So i have been using my external firewire HD to bootup my old macbook info. by restarting my iMac and holding down the option key...i have been doing this for several months now with no problem till today. I first noticed when i booted up my external HD that my iMac HD was not showing up on my desktop. I thought nothing of it at first...but then when i tried restarting my iMac regularly all that showed up on the gray startup screen was a gray file with a "?". I restarted the iMac back up using my external HD to try and repair my iMacs disc but it have me this message:

Verify and Repair disk "disk0s2"
checking HFS Plus volume.
Invalid node structure
Volume check failed.

Error: The underlying task reported failure to exit


1 HFS volume checked
1 volume could not be repaired because of an error

and thats it. any one have a clue what I can do to fix my iMac's HD???

    Welcome to Apple Discussions

    You'll need to use your Install Disk 1 and repair your Startup volume, the instructions are in the link below.

    Hi

    If Disk Utility won't fix it, you may want to try either DiskWarrior from Alsoft or TechTool Pro from Micromat.

    If Disk Utility did not repair the problem on the first attempt, run it again, as the second or third attempt can be the charm:)

    That's a bad spot to be in, then, as Disk Utility is a good utility generally considered to be bested only by those mentioned, that you must pay for.

    You haven't mentioned if Disk Utility still shows the drive as being "S.M.A.R.T. Status: Verified"

    If not, then running the Apple Hardware Test may tell you if you need a warranty replacement, in which case you won't need to purchase another utility.

    Means that it probably does NOT need warranty replacement. If it was faulty, "S.M.A.R.T. Status: Not Verified" would show. Your best bet now is DiskWarrior.
