Building notes, projects, and occasional rants

Nice surprise

Some months ago, I bought a external firewire DVD burner to use with my Mac. Today, I was browsing for something in System Profiler, and I discover this:


Firmware Revision:  1.04
Interconnect:   FireWire
Burn Support:   Yes (Vendor Supported)
Profile Path:   VendorSupport.drprofile
Cache:  2048 KB
Reads DVD:  Yes
CD-Write:   -R, -RW
DVD-Write:  -R, -RW, +R, +RW, +R *DL*
Burn Underrun Protection CD:    Yes
Burn Underrun Protection DVD:   Yes
Write Strategies:   CD-TAO, CD-SAO, CD-Raw, DVD-DAO
Media:  No

Notice the DL under DVD-Write. Apparently this drive supports double-layer writing, and according to the NEC product page and a review at, it really does support it.

I did not know that. I don't remember buying this drive as a DL drive. Cool! I can now backup my Audible files to DVD.
