Panther and Plextor PleXWriter PXW4824A CD-RW (10.3: Add support for any third-party CD-R burner
Authored by: mech_filter on Jun 21, '04 02:44:14AM

This overall hint (once you've read the details, like using drutil info to get the exact string you need to identify the drive, which may have an odd amount of whitespace in it) in Panther, 10.3.4.

Here's a .drprofile file for /Library/DiscRecording/DeviceProfiles/ for a Plextor PXW4824A PleXWriter 48x/24x/48x CD-RW drive (I named it PX-W4824A.drprofile).

      </dict>
      <key>DRDeviceProfileVersion</key>
      <integer>1</integer>
    </dict>
  </array>
</plist>

Save it and reboot (not just logout). If you want it only for your use, put it in ~/Library/DiscRecording/DeviceProfiles/ instead of /Library/DiscRecording/DeviceProfiles/ while if you put it in the root /Library/DiscRecording/DeviceProfiles/ location, make sure it is world-readable or other users may not be able to use it:

sudo chmod a+r /Library/DiscRecording/DeviceProfiles/*.drprofile
in the Terminal.

Before I installed this, drutil gave the following (bad) results:


 Vendor   Product           Rev 
 PLEXTOR  CD-R   PX-W4824A  1.05

   Interconnect: ATAPI
   SupportLevel: None
          Cache: 4096k
       CD-Write: 
      DVD-Write: 
     Strategies: 

It basically knew jack about the drive, and would not even assume it to be a CD writer at all.

AFTER installing this .drprofile, drutil gets everything right about it (and it works just fine in iTunes, which seems to be really picky about all this stuff being just right, judging from the problems reported by others, above):


 Vendor   Product           Rev 
 PLEXTOR  CD-R   PX-W4824A  1.05

   Interconnect: ATAPI
   SupportLevel: Unsupported
          Cache: 4096k
       CD-Write: -R, -RW, BUFE, CDText, Test, IndexPts, ISRC
      DVD-Write: 
     Strategies: CD-TAO, CD-SAO, CD-Raw

PS: You'll note that I have added specific max read and write speeds to it. I carefully checked out reviews and other information on this drive, and even the manufacturer admits that it does not perform properly at the 48x max speed (which isn't even enabled by default anyway). Plextor even warns that running it at 48x can "damage discs or even the drive itself"! They even said that their drive tray has been redesigned to prevent the escape of any fragments should the disc "explode" (their word, not mine)! Go figure. Anyway, their recommended max is 40x, so that's what I set it to. I don't think any of us need exploding CDs, thanks.

PPS: If you've upgraded to a high-speed CD-RW drive in hopes of speeding up iTunes importing, sorry but don't expect much if any improvement (though write speeds will improve). The speed limit on importing (e.g. ~8.6x on my 733MHz G4) is a factor of CPU - the upper limit is simply how fast your computer can do the MP3/AAC encoding. You can demonstrate this to yourself by copying the AIFF files off the CD onto your desktop, drag-drop them into iTunes, and then select them in iTunes and pick Advanced | Convert Selection To...; you'll see that it does the conversion at the same speed that is your max importing speed directly from the CD (unless you have something like a 4x CD-R/RW drive! Heh). Oh well.

Use PatchBurn!

I tried several of the above solutions. I did not work (NEC burner) found the easiast solution in the program PatchBurn II. You can find this at http://www.macwelt.de/magazin/0310/PatchBurn1.1en.sit
