A hard drive for the SE/30 — The long rescue

After the unexpected setback with the hard drive extracted from the Quadra 950, I once again rummaged inside a couple of boxes with stored assorted vintage stuff in search of a possible candidate. I found a few hard drives (both SCSI and IDE) in “I honestly don’t remember” conditions, so I took out three SCSI drives and put them in my external drive enclosure, connected to the Macintosh Colour Classic. The first drive, a 500 MB Quantum-something, made a few terrible clicks while trying to mount, and repeatedly failed. The second, a nice 9 GB Seagate ST39140N made a low humming noise when I powered up the SCSI enclosure, then silence. All the diagnostic tools at my disposal didn’t even detect its presence on the SCSI chain. The third, a surprisingly compact and lightweight 1.2 GB Quantum Fireball drive, powered up and made all the right little noises that indicate a possibly functioning hard drive. Also, it was immediately detected on the SCSI chain, and FWB Mounter gave me hope:

FWB Mounter

There it was, SCSI ID 4, “Recoverable”. And the adventure began.

I tried to mount it with FWB Mounter, but mounting failed after two long minutes during which the Mac appeared completely frozen. I launched FWB Hard Disk Toolkit 2.5, but the result was the same. My initial approach, I have to say, was to try to read and/or salvage any useful data stored on the drive before attempting a reformatting. Then I remembered I had a CD-ROM with a copy of DiskWarrior for the classic Mac OS (version 2.1, I think), so the fastest route was switching to a Mac with both a CD-ROM drive and a SCSI port. The PowerBook G3 Lombard was at hand, and fit the criteria. I booted in Mac OS 9.2.2, launched DiskWarrior, but it didn’t even detect the Quantum hard drive in the SCSI enclosure. I rebooted in Mac OS X Tiger and tried DiskWarrior 3 under Mac OS X. Same result. I rebooted again in Mac OS 9.2.2 and launched Disk First Aid, which did detect the drive but gave up almost immediately during the verification process, saying something along the lines of “This disk has too many errors and I can’t repair it.”

Since I still have all my Compact Macs out these days after performing a general check-up on them, I took the Macintosh Classic, connected the SCSI drive enclosure to it, and launched Norton Disk Doctor. At first, it didn’t detect the Quantum drive, but after issuing the “Show Missing Disks” command, the drive showed up. Clicking on Examine started a very long process where Norton Disk Doctor appeared to be running in slow-motion. After twenty minutes with the progress bar in the “Checking for bad blocks” test that was not progressing, I skipped the test (as soon as the Mac registered my input). When it came to checking the drive’s directory structure, Norton Disk Doctor kept throwing alarming errors. It indeed tried to fix a few issues, but I was starting to get the feeling that whatever had been on that drive was irrecoverable.

From that point on, I dropped any attempt to diagnose or repair the drive and focussed on actually trying to format and mount it.

On the Macintosh Classic I have an older version (1.8) of the FWB hard disk utilities, so I launched HDT Primer and see what it could do. HDT Primer recognised the drive and let me perform a low-level formatting, warning that the operation would take 81 minutes. I let it work and went to my studio to take care of other business. When I returned to the living-room after about an hour, HDT Primer was already done, and a dialog box informed me that the hard drive had been successfully formatted. So I went and tried to initialise/partition it, but unfortunately I kept getting errors.

Another frustrating chapter was beginning: trying different applications (on different Macs) to create partitions and logical volumes on the disk. Since I knew that that Quantum Fireball drive had bad sectors, I figured that the best course of action was attempting to partition it in different ways, so that maybe I could at least get to a point where, say, two out of three or four partitions were in a good-enough state to be mounted as volumes. After many, many fruitless efforts, and with Apple’s Drive Setup being this close to succeeding, my friend Grant Hutchinson suggested I tried using Silverlining Pro. I looked in my archives and found an old copy of Silverlining, then a newer one (Silverlining Pro 6.1). Thanks to Silverlining Pro 6.1 I could install a proper driver on the drive and managed to create two partitions of roughly 600 MB each; then, with version 6.5.8 I was finally able to initialise and mount one of those partitions.

I then used Norton Disk Doctor again to see whether such partition was good enough — and again, the “Checking for bad blocks” test was taking an inordinate amount of time, so I skipped it, assumed there were bad blocks, and let Norton perform the remaining tests. The disk passed them all, and knowing that the directory structure was sound was enough for me. With the disk now mounted on the PowerBook 1400’s desktop, I carried out some informal tests of my own, copying files to and from the partition (which I simply called “Q1”), launching applications from Q1, unmounting and mounting Q1 several times, and so forth. All went well, and I was actually surprised at seeing how fast this drive is in reading/writing files. Again, thanks to Silverlining Pro I was able to instruct the drive to mount automatically the Q1 partition when connected. Then I powered off the SCSI enclosure, disconnected the drive, changed the jumper configuration so that the SCSI ID was 0 instead of 4 (as it should be for an internal drive), opened the Macintosh SE/30 and mounted the Quantum Fireball hard drive on the metal shelf.

Drive inside the SE30

As you can see, the Quantum Fireball drive is rather slim (just so you have an idea: the former 40 MB beast of a hard drive that was inside the SE/30 weighed 850 grams, this Quantum Fireball weighs less than 250 grams).

I closed the SE/30, connected it to the mains, and turned it on for the moment of truth.


This, appearing at startup, was comforting. Then of course I got the floppy icon with the flashing question mark. Normal, since there wasn’t yet a valid system software installed on the drive. So I took the original set of floppy disks for System 7.0 and inserted the first one. After choosing a System 7.0 installation tailored for the Macintosh SE/30, it was time to see whether the Installer would recognise the Q1 partition… and it did! Once installation was complete, I restarted the SE/30 and it booted into System 7 in roughly 20 seconds. I was amazed and also very happy that my efforts and the time spent on this hadn’t been a complete waste…

Q1 mounted

So now the Macintosh SE/30 has a working-enough hard drive. Of course, it’s a temporary solution (the drive has a fair amount of bad sectors), but for now it’s usable, and even if I cannot take advantage of all the original 1.2 GB of storage space, a 620 MB partition for this system is far more than enough.

  1. in the cristmas time i gave my new aztec monter a try. its a small scsisata-converter, a guy in japan sells them via ebay. in point of a »cultural history« view this upgrade is an invention, because there is no noise (if you’re using a 2,5 hd or ssd 🙂
    the performance of small data packages is quite disapointing (slower than the original hd), but impressive with larger ones. unfortunately three healthy scsi-disks died in the last months. so its a lifeboat for the future …

  2. Oh wow. 620 MB? In HFS? What’s the block size on that critter? 32k? I remember that being the main reason for me to move to HFS+, that it supported more (and thus smaller) blocks and was therefore suitable for larger disks.

  3. Uli Kusterer: Heh, something like that. I tried to repartition the drive to have smaller partitions, but the process failed repeatedly. As soon as I got a working, mounting partition, I stayed with it. The block size is not much of a worry, anyway. 620 MB for a Macintosh SE/30 is overkill. I have already transferred on it many of the applications and games I use most, and there are still 500 MB of free space…
