    I'm trying to backup with time machine and was having problems, when someone in this thread: http://forums.macrumors.com/showthread.php?t=1299586 suggested I use the disk repair feature to see if there were any errors on either of my drives. Turns out there was.

    I haven't been able to back up my Macbook for a while now because of this problem, and now I have to repair the disk.

    If I do this will this wipe my data? Is it in any way possible? I'm a bit worried especially because now I haven't done a backup in a while. I also Don't remember getting any insulation disks, it did already come pre-loaded with Lion.

    I'm also overseas and don't have my receipts with me for the purchase of the Macbook, but will be going back to Australia in feb.

    Internal shows three red error messages. Here is the whole log though:


    Verifying volume “Macintosh HD”
    Checking file systemPerforming live verification.
    Checking Journaled HFS Plus volume.
    Checking extents overflow file.
    Checking catalog file.
    Checking multi-linked files.
    Checking catalog hierarchy.
    Checking extended attributes file.
    Checking volume bitmap.
    Volume bitmap needs minor repair for orphaned blocks
    Checking volume information.
    Invalid volume free block count
    (It should be 7200162 instead of 6449847)
    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.

    Also, can someone please tell me exactly what this means? Does this mean my HDD is physically damaged? I think it's still under warranty, but I'm not even sure what the extent of the damage is yet.

    Thank you.

    your HDD is not actually physically damaged. Word did this to my disk in about 8 places. Boot up with the OSX install CD (SL) or the recovery partition (Lion) and run repair in the disk utility. You may have to run it more than once (i did about 8 times). backup before and after doing this.

    Yeah once again, I don't think you read my post.

    I CANNOT BACKUP!

    He said to back up BEFORE I run the repair, but in order to do the repair I need to back up first. Know what I mean? Kind of a chicken or the egg situation.

    You can repair the disk without backing up, or you can try a different backup app, such as Carbon Copy Cloner.

    why can you not backup? I backed up when i had a corrupt disk without any problem. of course, i will not restore to that particular backup, but i wanted to have my fata safe.
