I have to agree with the other folks who say that "minimal" is about the most polite description they can come up with for the state of the documentation for the Disk Arbitration framework, and while the source code to disktool is a useful example, it does appear to use a lot of private, or at least deprecated APIs (although, it may be that I just need newer source). Hopefully the copy of "Mac OS X Internals: A Systems Approach" I just ordered from Amazon will shed better light on the APIs. You must use DADiskPeekCallback() to issue the DADiskClaim() ahead of time. I'm working on a disk formatting utility to support some specialized media and file system types, and I'm running into a bit of a problem with Disk Arbitration. I don't seem to be able to prevent the disk insertion (unrecognized volume) dialog from appearing after I issue a low- level format call to the device. Currently, I use diskutil to unmount the disk (if it was mounted - it's possible that there is unformatted media in the drive, and therefore no IOMedia object). I register a disk appeared callback to the Disk Arbitration framework. I then ask the driver to format the media - if it had an IOMedia object, it tears it down, and formats the disk, and re-enables polling. In the disk appeared callback, I call DADiskClaim, in an attempt to prevent the unrecognized volume dialog from appearing. Apparently it's too late at this point. My diskClaimed callback gets called, the disk gets partitioned, and everything proceeds normally, except that there is an unwanted dialog on the screen. _______________________________________________ Do not post admin requests to the list.
