Disk Utility message said my disk needed to be repaired.

I was running disk utility before I downloaded and installed Lion, but I just got a message

"The volume Macintosh HD was found corrupt and needs to be repaired.

Error: This disk needs to be repaired. Start up your computer with another disk (such as your Mac OS X installation disc), and then use Disk Utility to repair this disk."

Which disk do I use - I have a Mac OS X Install DVD and a Mac OS X Snow Leopard CPU Drop in DVD.

How do I start up my computer with that disk?

Thanks.

iMac (late 2009), Mac OS X (10.6.5), iPad ios 4.2, Apple TV (second generation)

Hello

you do not need any cd to perform a disk repair / check , you need to start in single user mode

restart your mac , just after startup sound hold on , Comande and "S" key on key board togather until fall in comande line interface

type at cursor this

fsck -fy and validate by press enter key

then WAIT until the end of verification / repaire processus ( may take long time ) when cursor appear again

type at cursor

exit and validate by press enter key

the only way that i have come across to fix this problem is to boot from another mac osx partition or the instalation CD/USB and go to the disk utility and then click on the hard drive in question and then push the "repair disk" button , this takes about 4-5 hours but seems to do the job , hope this helps

4-5 hours! That's not right.

it depends completely on the extent of the problem and size of HDD/SSD , for my 5TB raid it took 4hours 30 mins , but i suppose that smaller and faster harddrives will repair quicker than my massive RAID

I guess that explains it. Normally should be much faster.

How is your 'Massive Raid' configured?

i am running a raid "0" of 5 x 1TB drives and i configured it via the apple RAID utility , i used raid 0 because the OS can only see one 5TB drive rather than 5 x 1Tb drives

Then how come you keep giving the wrong advice regarding resizing partitions to other posters, are you trying to damage their installations, or just don't know how it works!

i was writing those replies with the wrongfull assumption that bootcamp partitions work the same as osx partitions and as a result i was corrected , just a stupid error on my behalf thats all

An error that could really screw someone up.

Read the TOU, do not post advice unless you have tried it, and know that it works, it's not your computer or your time that gets wasted.
