    Hi

    I've had a mac for just over a year but wouldn't be the most experienced with the inner workings of them. Anyway here's my problem.

    I started up my Macbook as normal the other night and instead of loading up the os I got this sign -

    TS1892_1.gif

    I tried all the solutions on the apple support page -http://support.apple.com/kb/TS1892

    and none of them worked so I tried reinstalling os x. But this leads to another problem, when it get's to the step - "Where do you want to install" it won't find my hard drive so I can't go any further.

    I did a hard ware test on my Hdd and it says "Test failed - invalid b tree node size"

    Any suggestions? I'm presuming I will have to get it off to get repaired but is there any hope of my files etc not getting completely wiped?

    Thanks in advance for any advice offered.

    When you are doing the disk check are you doing it after booting from the install disks.

    If that is the case, then it is probable that the disk is fried.

    If you have been not been booking form the install disk to do the disk check try that.

    Get a firewire cable and connect your mac to another mac with it. Turn on your mac while holding the 'T' key down. your mac will start up in 'Target Disk mode' and should be seen by the other Mac as an external firewire drive. Your mac will display the firewire symbol on a grey background. If your disk doesn't appear in the finder on the other mac then it is either physically damaged, very badly corrupted or there is a logic board problem. Most likely you'll have to go down the data recovery (very expensive) route.
    Bit late saying this now, but everyone should use Time Machine for regular backups to an external drive or better still 'Super Duper' to make a clone of it - these two programs have got me out of trouble more than once.

    as jpfahy above said try the target firewire route first as you are getting a b-tree node error it is definitely the drive that is faulty and not the logic board, as if its under warranty and you want it repaired by an aasp apple require the return of the faulty part, if you dont want to return it they charge you an extortionist price, so if you require data recovery you are better off doing the repair yourself, very easy just get a 2.5" sata drive, pull out the battery, remove the 3 screws on the ram guard and pull out the drive, hey presto. If you need a takeapart or anything drop me a pm, or check out ifixit.
