Burning CDs

on the PowerBook

500, 190, 5300 and 1400


The Good:
You can do it.

The Bad:
Slowly.

The ugly:
With limitations.


OK. I have a confession to make. I burn CDs infrequently on myPowerBook5300. The most I do actually involves packet writing usingAdaptec's DirectCD. There're two reasons why I don't use my PB foraudio CDs or archival backups. First, the 5300 is not a great machinefor burning, due to the speed of its SCSI bus. Second, I don't wantto tie up my PB with burning activities - I use my 5300 at work andat home and a dedicated burner it cannot be. So instead I use adedicated Quadra 700 which is amuch better machine for the job. An incredibly cheap Quadra605/LC/Performa 475 or Centris 610 will also do the job really,really well at very little cost.

So before you think about burning CDs with your 'Book, you shouldreally think about whether it's just going to be occasional use, orwhether you're going to make stacks of music CDs and data backup CDs.The limitations of the non-PCI PowerBooks aside, the software andhow-to sections might prove useful to people using newer PowerBooks.Similarly, if you're using a 100 series PowerBook, don't beput off!! Many people have used both Duosand PowerBook 160s and 180sto burn CDs successfully. This includes PowerBook150s as well. On the 160/165/180, as long as you max out the RAM(14MB) and run a fairly spartan system, you'll have no trouble. Dittothe Duos and PB150, although they're a bit easier as their RAMcapacities are that much larger. The 100-series PB run the same oldSCSI chip (see below) as the 68LC040 and early PPC PowerBooks (5300and 1400) and thus the difference in SCSI throughput is nominal andis not particularly affected by CPU speed. I don't know whetheryou'll be able to do it on your maxed-out PowerBook100, but I'll let you in on a little secret: install Toast CDReader 4.0 on your Mac Classic and the damn thing works with your CDburner! (No, I'm not game to write a column entitled 'Burning CDs ona 4MB Mac Classic'). So. The bottom line here is what I'm going tosay here essentially applies equally to the 100 series 'Books.

There's a reason your PowerBook 500,190,5300 or 1400isn't an optimal choice for burning: none of these Macs support SCSIManager 4.3 I'm not going to explain it here; download Horst Pralow'soutstanding SCSI utility Mt. Everythingwhich has a detailed explanation of it. But briefly, SM 4.3 permitsmuch faster SCSI throughput as it not only involved a completerewrite of the SCSI management software in the Mac OS, but also a newSCSI chip.

Despite not having any NuBus slots, these four PowerBooks areesentially Duo-based and therefore represent NuBus architecture. Thefirst PowerBook to support SM 4.3, the 3400,has PCI-based architecture. In summary, these PBs have pretty slowSCSI. To make an unscientific comparison, the best SCSI throughput Iget on my 5300 to a Quantum Fireball drive (SCSI-2) is around 520Kper second. On the Quadra 700, I move data at 1.7MB (yes, that'smegaBYTES, not mere megaBITs) per second. When you consider thatburning at 6x requires a constant data stream of 900K per second (8xat 1200K p.s), that's a considerable difference.

Nevertheless, it's possible to burn on these PBs. It can even beuseful if you need to burn CDs at different locations. The only thingis to appreciate the limitations. Such as:

  1. 1. You will never, ever burn at faster than 2x. Otherwise, you can start your own coaster factory.
  2. 2. You may not get audio play-through on the 500, 190 and 5300. 1400s with CD ROMs are fine. But there's notionally no playthrough on the other three. I say 'notionally' because until recently, I thought this was written in stone. However, I have managed to get audio CDs to play on the 5300 with no special audio lines - just via the SCSI bus and through the 5300's mixed stereo speaker. The trick here was using CD ROM SpeedTools as the driver, rather than Toast's. Toast wouldn't let me mount the (Audio) CD on the desktop; CDRST would.

Frequently-Asked Silly Questions:

Q: Can I use an IDE burner?

A: No you can't. Stay away from them. They're lousy anyway(there's a reason they're 100 bucks cheaper and it's called having tosuffer installing them on intel hardware. You'll have successfullyburned 3 dozen CDs (even at 1x) before your wintel-toting friend hasfigured out the jumpers and the master/slave/secondary master configon his Compact eInterWeb whizbang Stinkpad 1GHZ 6000. The upside forhim/her is that all their friends will not be asking Mr/Ms. Wintel tocopy CDs for them. Given that Adaptec's stuffed full of defectingApple engineers when times got tough in '96, they also churn outoutstanding Mac burnerware and completely incomprehensible PCburnerware. This may not be entirely their fault as 'interfaceguidelines' essentially don't exist in the wintel world).

Q: Can I use a FireWire or USB burner?

A: Nyet. SCSI only.

Q: Can I get an internal CDR?

A: No. Well, not unless you happen to own aWallstreet/Lombard/Pismo as well, that is.

Other Excellent, Useful Stuff:

What you need:
 
  1. PowerBook fitting the above description
  2. SCSI CD burner
  3. HDI-30 SCSI cable-->Centronics 50M or DB25M (29 pin; see PowerBook SCSI for more info)
  4. CD burning software
  5. Blank CDR/CDRW media
I generally advise a newer burner (4x, 6x 8x etc) as you can keep it for when you upgrade your system. More importantly, newer burners have a much bigger RAM buffer, which's what your 500/190/5300/1400 needs. For example, the Panasonic 8x4 SCSI, which I still see (April 2000) new in the shops in Australia, has only a 1MB buffer. By contrast, the Yamaha 6416S and Panasonic 20x8 have 2MB. The newer Yamaha 8424S has 4MB and some newer Acer and HP models have 8MB. I haven't tested newer ones, but it may be possible to burn at higher speeds with stacks of buffer room. Though I'm not sure why you'd want to combine a high-end burner with a low-end PowerBook. But you might need to. However...
Optiona stuff:
  1. Ginormous (1.0GB minimum say) internal hard disk. Partition it so it holds your system and (say) a 750MB blank partition for CD mastering
  2. OK, so 1.0GB's not ginormous. A ginormous external SCSI drive is a better option. A Jaz, Orb or SyJet will also do the job. Don'tuse a Zip; it's too damn slow. If you've got a Zip, use it to store the files you want to back up later; transfer them to your burning partition on a hard disk when you've accummulated 650MB worth.
  3. An extra SCSI CD ROM drive (any speed will do)
  4. A terminator (possibly)
OK. So you've got the gear. Now what?


 

 
 
 

A fresh reboot helps. Make sure you turn off all extensions except necessary ones. Keep your CD driver, ISO/Foreign File Access and Toast Reader if you're using Toast or Jam. Better still, make a custom set of extensions with the Extensions Manager and call it 'CD Burning' or something. Make sure you turn off VM or RAMDoubler!!

But leave SpeedDoubler on!!

1. Put your data onto your master partition
2. Launch your CD burning application
3. Ensure your burn speed is set for 1x or 2x only (important)
4. Set the application to burn Mac volume, hybrid (Mac/PC) or audio CD (or whatever it is you're burning)
5. Do a simulation run if you want to make sure everything's OK.
6. Burn your CD.

See? Wasn't so hard was it?

If you're getting 'buffer underruns', you're cheating and you greedily set the write speed to 4x, didn't you? Put it back to 1x or 2x again and find a good book to read for 30 minutes or so.

The bottom line is to ensure you've configured your hardware and software correctly. If you're new to CD burning, read the manual (RTFM!;-). If you're a Toast/Jam veteran, the setup should be pretty quick and easy. As I say, if you're serious about burning 30 (or more) CDs per month, get that Quadra 605/650/800 or PM6100. But if you need to burn at someone's office, or need solid backups daily or weekly of your work, your PowerBook could just do the job you want it to, without lashing out on a brand new model.

And, let's face it, it beats feeding in floppies while you backup using DiskFit Direct ;-)

Good burning. Oh. Gotta go. Toast's ready.
