Hi all... Noticed that programs like DiskTop and Sum TuneUp can display the icon of the disk (especially the SCSI hard drives). I'd like to extract the icon from the disk driver - but there's no clue in the Tech Notes (except for how to get it from the .Sony driver) Anyone knows how? Please mail direct!!

The driver calls to get the disk and drive icon are standard. To get the disk icon from a driver, make the call: pb.ioRefNum = driverRefNum; pb.ioVRefNum = driveNum; pb.csCode = 22 result = PBControl(&pb,false); if (!result) { // the long word at pb.csParam contains a pointer to the disk's icon } To get the drive's icon, do the above, except set pb.csCode to 21. The icon returned has the same structure as an ICN# resource, i.e., 128 bytes of icon data followed by 128 bytes of mask. Oh, for the drive icon, right after the mask is a Pascal (length byte first) string containing a description of where the drive is (that's the description to the right of "Where:" in the Finder's Get Info window). If there's no description, then the first byte after the icon mask should contain a zero. steve -- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Steve Christensen Never hit a man with glasses. stevec@apple.com Hit him with a baseball bat.
