I am restoring a LaCie Tsunami 240 external disk for the Macintosh. I found a replacement Quantum LPS240 and the hardware side is well on its way.

This drive displayed a custom icon in System 7 (a small icon looking like the drive itself), instead of the standard "rectangle" drive which is default for most HDs.

The question is, 1) what setting controls drive icons in System 7 and 2) if anyone can share this icon, as mine was lost when the original disk failed.

  • I found a shot of the icon in my thread detailing drive recovery: twitter.com/0xF2/status/…

    If you have a picture of the icon you can just edit a gif with the same image and apply it by copy and paste to the folder. Most of the icons were 32 x 32 pixels. The icon is actually stored in the resource Fork and can be manipulated with ResEdit. ResEdit let you fiddle with application icons as well. Commented Oct 22, 2022 at 19:09

LaCie drives were supplied with a software package, called Silverlining. That package would have initialized (created a filesystem on) the hard drive, and would contain any custom icon that you might remember.

Moving icons onto files, or drives, can be accomplished in the 'get info' view (select a disk icon and command-i to bring up disk info), by cut-and-paste.

Some (not all) of the Apple 'Disk Tools' software would initialize (create file systems and partitions) on a raw SCSI hard drive, but early versions of that software would reject non-Apple hard drives, so a custom filesystem initializer was included with third-party disk drives.

    I think I used Silverlining once upon a time, and recall it had a brilliant dialog. If an operation was in progress and you tried to cancel it, you'd get a dialog with a message suggesting that if the operation was not run to completion it would be need to be redone from the beginning, with choices "OK" and "Cancel". I don't remember which button had which effect, however.

  • Are there any copies of Silverlining left on the Internet?

  • @0xF2 My "Silverlining(R) Starter Kit" folder in an old backup does have Silverlining 5.8.1 (dated 1997); internet-available versions look too new for this use.

    I found two copies of Silverlining online. The older one had a selection of pre-configured LaCie drives, including a Tsunami. It was able to update the drive's driver w/o re-init, and the icon is fixed. Yay!

There are two main ways for there to be a non-default drive icon.

  1. The device driver can have a custom icon: I believe these are restricted to being a black and white bitmap
  2. A custom icon that is pasted in in the Finder: These can be up to 8 bit color if I remember correctly

The easiest solution for you would be to use a custom Finder icon and paste it over the default driver icon that you are currently seeing. See Customizing Mac OS at the bottom of the web page.

I did a really quick search and couldn't find any of the original icons. Finding pretty much anything predating OS X now is daunting.

  • I remember an application which would go through all of your other applications and copy the icon resource out of them. It may have been part of Resedit Commented Oct 22, 2022 at 19:07
