I was reading a review at anandtech and they mentioned CD-MRW or Mount Rainier. They were vague about it though. What is it? Just curious, thanks.

technical and detailed answer: http://www.cdrinfo.com/Sections/Articles/Specific.asp?ArticleHeadline=Mt.%20Rainier%20Format&Series=0


short answer:
Its basically a standard that lets you treat the cdrw like a floppy drive. You can drag and drop files and erase stuff just like a normal disc.

Is that what DirectCD is/was?

Direct CD needs formating, and closing.

But the general idea is the same right? CD-MRW just makes it more like a floppy.

yes same thing. Mount Rainier also needs formating, but its all done in the background. Its the same technology except DirectCD was software, the computer had to run the software to work. This is hardware based.

it's controlled packet writing, that needs to be supported in both hardware and in the OS itself. Because it is hardware based though, it should be faster, and have less, if any, C2 errors in the writing. It also shouldn't crash anything, which Direct CD/InCD can do, though I've managed it nonetheless. I'm skilled.

Choose, the Lite On did upgrade the drive to use mt rainer in recent flashes, it didn't ship that way. Lite On...in fact, most drives started shipping with Mt Rainer support with 48x drives. The standard was actually around before that, but software needed to support the format before anyone was willing to ship with it.

Hmmm...gonna check to see if my plextor 12/10/32 has this capability

Btw I really hated direct cd.

EDIT: nope. too bad. too old

how do you use this? is there any software or do you literally use it like a zip disk or something?

theoretically, you don't need software - only XP has yet to add support for it, as I understand. In that case, you need software, like Direct CD or InCD or Sonic or whatever.
