Is there a way (aside from the "Facade" init) to alter the icon of a hard disk? I'd like to edit the icons for my hard drives, but can't figure out how to do it... Suggestions? -- cdelay@cie.uoregon.edu "Stress gives me something to live for..."

Don't know why it shouldn't work, but I've never been brave enough to try it. Here goes: They say the icon is stored on the HD's boot blocks (notice it's not in the finder, desktop, or system...)so, get a visual copy of the icon you have now via a screen dump, etc. Hex dump it with McSink, etc. Use this hex code as a search pattern in a sector editor (norton, SUM, etc) and replace the found hex with a hex dump from the icon you'd prefer to have. I'm serious about this. If anyone has the guts to sector-edit his/her boot blocks, I'd like to know if this method works. I miss the sector-editing days of yore with my Apple //e.

The ICN# is usually stored in the driver itself. The hex replacement that you describe will work, but you need the mask too to make it look nice. HOWEVER: You run the risk of twiddling the wrong byte in the driver and making it useless. I played a part in developing a driver/partitioner package. We included a facility for the user to develop his own icon and change it on-the-fly while running the partitioner utility. The software is currently being shipped with some Everex drives, but due to their specification, the user interface is nothing to write home about. The driver is well written and has password protection and encryption built in. m. -- I don't settle for mediocrity in life. I deserve the best and don't feel bad about getting it because I put my time, effort, talents and power to use. I think this is better than complaining about not having something that someone else does. mkellner@polyslo.calpoly.edu July 1, 1991 -> apple.com

The HD icon is stored in HD installer's resource file. Just use ResEdit to edit it, and reformat the HD... although that means you must make a backup from your HD. -- H.Seung hseung@eniac.seas.upenn.edu 3820 Locust Walk #876 University of Pennsylvania Philadelphia, PA 19104

A drive's icon is a data structure returned by the driver. That data structure could come from anywhere. It's quite likely that the icon was compiled into the driver, in which case it would be in line with the driver code on the disk. Or it could be written to a special block on the drive by the driver or formatting software. Or it could be in line, but patched by the formatting software. If the formatting software defines the icon, it could well be in an ICN# in the formatting application, but that is not the case with most drivers. Incidentally, some drivers checksum themselves (or are checksummed by the Mac) and this could cause a patched driver to fail. I strongly suggest that you use Facade to redefine your drive's icon. That is assuming that your driver doesn't allow you to redefine the drive's icon, making this whole discussion moot. - Laird

I too, miss the old secotr-edting days of the //e. Personally, I would not really go so far as to edit up the boot sectors of my hard drive, because just one bit misplaced and it will NO LONGER have a boot track. Here is my suggestion: I use Silverlining to format my drives, because it is really easy to partition my drives, and allows me password control. What I was thinking ofd doing, but never got around too, was using ResEdit to edit the icon resource in Silverlining itself, then replace the driver. That way, silverling will take care of sticking it in there.

My Silverlining-formatted drive at work has an icon representing the AT&T Death Star, installed using just this method. My drive at home has a Calvin icon. You could also wait for System 7.0. In the "Get Info" window, you can replace the icon with one of your choosing. The second partition on my drive at home has a Hobbes icon installed in just this manner. -- Ralph Brandi ralph@mtunq.att.com att!mtunq!ralph R.I.P. Radio Canada International 1942-1991
