Repairing disk failed with error Could not unmount disk (-10000)

DW wouldn't fix the problem. What's it mean?
 
What disk are you trying to repair? Are you running Disk Utility from the hard drive, or from the CD when booted from the CD? Did you have other programs with open files open when you ran Disk Utility? That could prevent OS X from being able to unmount the disk, which it needs to do in order to make any repairs to the disk.
 
Ok, and you're sure that you're launching the Disk Utility program from the OTHER partition, right? If you launh Disk Utility from the partition you're trying to repair, it won't work.

Try booting from the OS X install CD and then launching Disk Utility by selecting "Disk Utility" from the menubar when you're asked to select a language. That'll make sure that Disk Utility can successfully unmount the disk you're trying to repair.
 
hmmmmmmmm. booted from install. repaired, n.p.
but it still exhibits the same behavior when DU'd from the other partition.
ah well.
 
I'll bet that some portion of Disk Utility is somehow, erroneously using files from the OS X partition you're trying to repair -- I remember this being an issue when people had Panther and Jaguar installed on the same hard drive on different partitions. Launching programs from Jaguar's Applications folder would cause the application from the Panther partition's Applications folder to launch instead, causing problems.

You mention that you have two partitions that have OS X installed -- when you run Disk Utility, are you selecting a partition to repair, or are you selecting the actual hard drive listed as a parent to the partitions? if you select the hard drive, and not a single partition, then Disk Utility must try an unmount all partitions that belong to that hard drive, which isn't possible, because Disk Utility is trying to unmount the partition you're currently booted from -- it can't do that.

What happens if you do this: Quit all running programs and unmount the partition that you want to repair (just click on it and eject it from a Finder window or the Desktop, like a you would a CD). Then, launch Disk Utility from the OS X partition that you're currently booted from. Next, in the sidebar where the volumes and hard drives are, select the partition (not the hard drive) you just unmounted, and try to repair it. Let us know what happens.
 
ProTools. 6 to be exact. ProTools behaves poorly when I doesn't have its' own part.
I have a part for 5 different versions of PT, plus a scratch drive part.
I've had no problems running my rig in this manner. Some folks insist I run in OS9, other times I'm running PT LE.
 
When you want to run DU on a drive with more than one partition, you can't run it from a second partition. You're running it on the partition from the drive you're trying to repair. You need to boot from the CD.
 
bobw: you can run Disk Utility on a drive with more than one partition -- I do it all the time. You just need to make sure you're running Disk Utility from partition number 1, for example, and trying to repair partition 2 -- not 1 and 1, not 2 and 2. Also, the partition to be repaired needs to be selected in Disk Utility -- not the parent device (the hard drive itself) of that partition, obviously, since you'd be trying to repair a device that has the currently booted system on it.

What I think was happening is a throwback to the days when Panther first was released, and people had Jaguar on one partition and Panther on the other. Trying to launch an app from the Jaguar partition caused the application to launch from the Panther partition, causing problems. That's why I suggested ejecting the partition you're trying to repair (of course, that can't be the startup disk, since you can't eject a disk that's in use) and then using DU from the currently booted partition to repair the ejected partition. That should make sure that no cross-launching of apps occurs.

I'd still like to hear back from metropical and see what results that had.
