How to "Factory Reset" a PowerBook G3 (PDQ) without an original software restore CD?

I want to wipe this computer clean because I am planning on selling it. Thankfully I have the troubleshooting manual to restore all original software (factory reset). In it it says that "some computers come with a software restore CD." I am not sure if mine did as it used to be my aunts, and she doesn't remember.


The point is I don't have the software restore CD.


I am wondering if there is a free .DMG that Apple provides so that I can download the restoration software onto another CD/DVD drive? Another option is to subscribe to Macintosh Repository to download said .DMG, but I don't want to as they don't allow downloads via VPN and don't allow you to download over 100MB without subscribing to them.


There should be a free option on Apple's website to download a .DMG. I know this is old software, but maybe it is archived somewhere?


Thank you for your time.

Thank you for the updated information.


The PDQ has a SCSI port for external devices (such as SCSI hard drives). The problem is that it is difficult to read a SCSI hard drive on a modern Mac or PC.


One alternative in this case would be to use a CompactFlash memory card (approx. 256 MB to 2 GB size should be fine) in an inexpensive PC Card adapter for CompactFlash. This adapter with the CF card would be placed in one of the PC Card slots of the PowerBook. Normally, the CF cards are PC-formatted, but can be reformatted to HFS+ = Mac OS Extended. This can be useful for (at least temporary) backup copies, and for transfers to other computers equipped with an appropriate memory card reader.

A Mac-formatted CF card containing a Mac OS 8.x to Mac OS 9.x system folder may even be bootable. I do not know whether this would work with the PDQ, but you may want to carry out a test by drag-copying an existing system folder to a CF card.

I am thinking about the last option you gave. About removing and erasing the hard drive (HDD). I thought this through a bit more.


I might want to save some of the software (e.g. Microsoft Office 98) as it came pre-installed when my aunt first purchased this computer. I perhaps want to save the pre-installed software, but erase all the personal files from the PowerBook’s HDD.


I imagine that macOSs Disk Utility would be out of the question at this point. So my only option that I can think of would be to selectively drag and drop files into the trash and into an external HDD. Which leads me to my next point.


I would like to save all the contents onto an external HDD. I realize that most…if not all of the software has piracy protection. I don’t plan on selling it. Just keeping it as a keepsake/memento. As with the personal files.


I am chuckling while editing this reply to you. I’m not even certain I want to sell this PowerBook at this point anymore. $100 USD isn’t worth the memories my aunt can tell using this machine. Those memories are priceless.


However, I would like to save the files and software in case the old hard drive stops working.


My aunt was a graphic designer; as am I in certain respects. This computer has old legacy/perpetual software like Microsoft Office 98, Adobe Photoshop 5.5, Acrobat Reader 4.0, etc. Some of it is abandonware at this point.


I researched if I could use these old apps on newer Mac models. Namely Macs that run macOS Catalina and above. They do not, as they are old 16/32-bit apps.


In conclusion, I think it would be better suited to modify instead of completely erasing this old hard drive if I do plan on selling this computer.


Here are my main questions:


  1. Would it be possible to drag and drop the files from the PowerBook’s HDD onto a newer external HDD. This external HDD has a file system of macOS Extended Journaled.
  2. Would using an M1 Mac running macOS Monterey 12.2.1 or alternatively, a Mac that has an Intel chip running macOS Catalina 10.15.7 make a difference? Which would you choose to do this operation?


The HDDs in PowerBook G3 Models had Mac OS Extended (HSF Plus) file systems. (Source: https://www.applerepairmanuals.com/the_manuals_are_in_here/PowerBook_G3_Series.pdf).


I imagine that if Disk Utility can still configure HDDs to Mac OS Extended format (even in macOS Monterey) then the newer OSs can open the old files as well. (I looked at the contents in the computer that I definitely want to keep and those files are TIF, MPEG, and JPG. So yes, I am able to view and edit them.)


Thank you for your time again.

Hi,


Restore software for this computer is not available for download from Apple. You could perhaps look for discs via an online auction site (such as eBay, or Tradera). However, a model-specific software CD must be for the exact model, or you would have to buy a subsequent operating system retail version (for all compatible models).

Otherwise, if necessary, you could just erase/wipe the internal hard disk, without installing an operating system. Earlier, there was an ISO file (dban-2.0.0_powerpc.iso) with a free third-party (DBAN) wiping utility for PowerPC Macs available for download. Once created, the disc would contain a small Linux system, which allowed the CD to boot at least some PowerPC Macs (when holding down the C key). This may or may not work with your PowerBook model. The utility on the disc could then wipe an internal ATA/IDE hard disk drive.


Alternatively, the hard drive could be (temporarily) removed from the PowerBook. One could then connect the now external hard drive to a USB universal bare-drive adapter. This would make it possible to connect the adapter to another Mac (or PC), and (using the appropriate software) erase the hard disk there.
