But as they say, it was a (Re)Learning Experience. Finally! Two hours after I started the process – LocalTalk would probably have been done in half the time.

It chimed, smiled its happy Mac face at me, then quickly and transparently mounted the external drive on the desktop. I held my breath booting up the Classic again.
Classic mac os archive mac os#
Launch, click Initialize, wait 15 minutes, and presto: one freshly formatted prehistoric Mac OS hard drive. The name goes back to the very first Mac external hard drive, and the interface is minimal at best, but version 7.3.5 still ran under OS 9. Using the Drive Setup utility included with Mac OS 9.2.2.Īnother distant memory surfaced: back in the System 7 days (and earlier), Apple used a different utility for formatting disks called Apple HD SC Setup. All I did was connect it to the Wallstreet, copy, and… reformat. When finished I reformatted the disk for good measure, again using Mac OS Standard.īack on the Classic, I got the same error: can’t read drives larger than 4GB. I grabbed another 160MB drive from my shelf, connected this to the Classic, and it mounted fine – yay! But this one contained some data I needed to backup first, so I again powered down, hooked the drive up to my Wallstreet, and copied what I needed. I clicked the Mount button and got an error message that drives larger than 4GB are not supported on 68k Macs.
The drive still didn’t mount on the desktop, but SCSIProbe did now see it on the bus – progress. Dug one out of a drawer, and bingo that solved problem number two. These classic Macs with their slow SCSI speeds didn’t typically require active termination, but it was the next thing to try. Still no go on mounting the external drive though, and now SCSIProbe was complaining about a lack of termination on the bus. I shut down and swapped the SCSI cable out for another.
The Mac booted but the drive didn’t appear on the desktop, so I used a floppy disk to load the SCSIProbe control panel and scanned the bus. Hmmm, that sounded like a motherboard component about to fail. If I moved the external SCSI cable even slightly the whine changed pitch. I configured my drive as ID 2, added a passive external terminator, and booted up the Mac.Ī loud whining sound immediately started emanating from the machine. Any external devices need to use ID 1-6, with a terminator. On older Macs the internal hard drive was set to SCSI ID 0 and terminated at the motherboard the system itself used SCSI ID 7. SCSI chains require each device on the bus to have a different ID number, and both ends of the chain need to be terminated.
And reminded myself why I like FireWire drives so much better. I then spent the next two hours trying to get this hard drive mounted by the Classic. I mounted the old (noisy) transfer drive, selected Mac OS Standard format, and quickly partitioned the disk. The Wallstreet runs Mac OS 9.2.2, and the included disk utility is called Drive Setup. 68k Macs require disks to be formatted in the Mac OS Standard (HFS) filesystem, not the newer Mac OS Extended (HFS+) flavor. I pulled an 80MB drive from my stack of spares, hooked it up to a SCSI sled (a coverless external case), and connected this to my PowerBook Wallstreet to format the disk. Since it was bootable and had an external SCSI port, I decided to hookup an external drive to copy the data rather than open the case and pull out the boot disk, or wait for things to sputter along using LocalTalk. They wanted to get this data transferred and converted to something modern. I was reminded of some of these working on a file transfer job this weekend.Ī client sent me a working Macintosh Classic II running System 7.0.1, with several old projects on the internal hard drive. SCSI did work, but not without challenges. Anyone who’s been using Macs since the days when SCSI was the primary expansion bus knows that this technology was not something often described as plug-and-play.
