Need Urgent Help

[laimonas.s]

hey all, i have a photography exam tomorrow, and it seems like theres something wrong with my mac.

Before the exam i thought i will do a regular checkup using Maintenance, and it came up with an error that my disk needs to be repaired.

So i have followed instructions and opened Disk Utility and clicked on Verify Disk.

This is what happens....

Now i would love to click "Repair Disk" but as you can see it wount let me.

Im terrified if something goes wrong with my mac i would be stuck in exam working on 1-2gb image files with crappy iMacs with 256RAM

PLEASE HELP!! thanks

P.S i havent noticed any bad "signs" apart from this...
