Hi All-
I'm having some issues with my MacBook with a bad B-Tree. I've read a lot about how to use DiskWarrior to repair it. I'm not really interested in recovering my data, but I would like to install OS X.

Those who've had a catalog issue or B-tree issue knows that fsck doesn't repair it.

I'm having an issue with the Disk Utility on the start up disk. It's having trouble reading the disk and hangs at "Gathering disk information". I would like to boot into single user more and repartition the disk, I just don't know how.

I have not had any success in finding my answer on the web, and am hoping that you can help out.


MacBook Pro, Mac OS X (10.4.10)

    If Disk Utility is having issues seeing the drive when booted from the DVD, there may be actual physical damage on the drive and it should be replaced.

    Regardless, instructions and examples for formatting a drive via command line can be found here:

    Disk Utility is also available at the command line. Open Terminal and type:

    <pre style="overflow:auto; font-family: 'Monaco'; font-size: 10px">man diskutil</pre>

    then press <RETURN> to view the man pages. I suggest that you give those man pages a good read, then come back here if you have further questions. If you cannot get to the man pages (if you don't have a working installation of OS X), I could give you a specific command to run, but I'll need to know absolutely everything about what results you want (just "repartition" is WAY too vague).

    Also, you might want to give Disk Utility another try, and give it plenty of time to handle the broken file system. Sometimes, a broken file system will become available for formatting, but only after an extended period of time (several minutes to an hour).

    Thank you both for your great replies. I managed to find it in the 10.4 Command line.

    I tried running some man pages, but man doesn't seem to be on the CD, which is bizarre.

    In any case thank you again!
