Invalid Volume file count .... HELP PLEASE

How can i fix it? I haven t made an start up disk nor any backup yet? Is it fixable or do i need to do an fresh re install of osX

It's quite fixable, although if this happens often that's not a good sign.

1. Start from your Mac OS X Install disc: Insert the installation disc, then restart the computer while holding the C key.

2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.

3. Click the First Aid tab.

4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.

5. Select your Mac OS X volume.

6. Click Repair. Disk Utility checks and repairs the disk.

If your using one of the new Macbook Air's substitute 'Install disc' with your USB Install Flash Drive (that came with your Air).

a reinstall wont do you any good.
so there are two possible solutions, one better than the other. of course goes with out saying, backup as much as you can before attempting anything.

first off you will need to boot off the usb stick that came with your mac, just plug it in and hold option/alt down while it is turning on, and select to boot from the usb.
once you are in you are going to want to open disk utility, located in the "tools" in the menubar atop. from there go to where your at now and click repair disk. - you have to do this while booting off the usb as you cant repair your boot disk.

if that doesn't work there is only one way, the hard way.
within diskutility (still booting off the usb) simply reformat your drive, then reinstall from scratch.
