Q: Can't repair disk using Disk Utility
Hi, my MacBook (10.7.6) was freezing frequently and I was not able to use Command+Option+Esc to safely force quit. I would only be doing light Internet surfing whenever the laptop froze. No new software or hardware installed recently either to cause the problem. Anyone encounter this problem too?
Tried using Disk Repair and this is the message I get: disk utility stopped repairing macintosh HD. Disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk and restore your backed-up files.
Under the details of the disk repair process, the following items were highlighted in red.
1. Checking volume bitmap: volume bitmap needs minor repair for under allocation
2. Checking volume information: the volume macintosh HD was found corrupt and needs to be repaired.
Volume repair complete.
3. Updating boot support partitions for the volume as required.
Error: disk utility can't repair this disk...restore your backed-up files.
Appreciate any help you can give on what the underlying problem could be and how to reformat the disk now.
Thanks in advance!!
MacBook, Mac OS X (10.7.5)

You have OS X Lion, so you don't need a DVD, just start from Recovery.
1. Press Command and R keys while your Mac is starting and open Disk Utility.
2. Select Macintosh HD in the sidebar and repair the drive.
If it can't repair the drive:
1. Make a Time Machine backup.
2. Press Command and R keys while your computer is starting, open Disk Utility, select Macintosh HD in the sidebar, select Erase tab, erase the drive and close Disk Utility.
3. On OS X Utilities window, select the option to restore the backup and follow its steps
