Lacie Won't Unmount - Applications Running

[gmachen]

The plot thickens!

OK, after some more experimentation, it now appears that it's not SD! per se that has to "touch" the drive before it will unmount, but *any* app launched as root has to do something to the drive before it will unmount:

- Immediately after a bootable backup by SD! launched as root, I was able to unmount the offending partition from the Finder in my regular Admin account. Had I mounted it again by any means (e.g., Disk Utility, restart), it would not have been unmountable, as before.
- I promptly launched Disk Utility as root. Even it would not unmount it. But I "touched" the drive by merely doing a Verify Disk Permissions (which I would think is a read-only operation), quit, then lo & behold, I could unmount it from the Finder in my regular Admin account.
- But one time only! If I mounted it again, even in Disk Utility launched as root, it wouldn't unmount by any means until I had "touched" it again with another Verify Disk Permissions in Disk Utility launched as root (or presumably any other app launched as root that 'touches" the drive in some way).

This would seem to be an OS thing, not so much a SD! thing.

To review:
- Only a partition containing a bootable backup made by SD! (either launched normally or as root) will not unmount. The drive had been partitioned into two volumes with Apple's Disk Utility under 10.4.11.

I've not yet tried a single-partition HD containing a bootable backup made by SD! launched as root. (I'll try one and get back to you all here.)


Edit: P.S.: I can get it to unmount by doing a Verify Disk Permissions in Disk Utility launched in a normal Admin account, but that's probably a moot point, because I think all Disk Utility does is run the routine as a shell for the command line diskutil, which probably runs as root anyway.
