disk utility repair futility

[Wie Gehts]

Hey folks...
this is really starting to get my goat, to put it nicely.

Whenever I happen to get a 'disk needs to be repaired' and then run the disk utility repair from my installation disk, it has always so far, reported that the disk didn't need any repair after I run it.

For example, my computer was acting a little strange so I ran Onyx. It told me the hd needs repair. So I run off the installer and, of course, it says no repairs needed. And when I reboot from my hd and run onyx or disk utility, it says it needs repair. The freakin' repairing off the installer disk never works. Its becomes a vicious cycle. It always has done this and now I'm really irritated.

What usually winds up happening is that after shutting down and using the computer a few times, it'll go away.

Am I supposed to shell out a 100 bucks for disk warrior for what this &*!%^* useless and pointless disk utilty is supposed to do in the first place?

Thanks :)

Restart your computer while pressing the [S] key. (This causes the computer to startup in Single-User Mode. You will see a fullscreen commandline interface.
At the command prompt, type fsck -fy. (This runs File System Check and forces the OS to accept repairs repairs to your hard drive.)
If any repairs are performed, then rerun the fsck -fy until no additional repairs are required. If fsck identifies problems but doesn't seem to repair them, then you should shutdown your system until a qualified technician can examine it.
If your system is reported to require no additional repairs, then type either exit or logoff. (Either will do.)
After going through a lengthy routine, your computer should eventually return the traditional MacOS X GUI.
