According to item j in:
http://www.softarch.com/us/products/WriteCDRW/mtrainierfaqs.html

legacy CDRW drives will not be able to write in Mt. Rainier
format. Is this because Mt. Rainier format is set up
(purposely) in such a way that even special software on legacy
drives couldn't emulate writing to it, or is it that the
drive/software makers are too lazy or deem that there's no market
for emulation?

Let say that since Mt. Rainier has a minimal granularity of 2K
bytes and legacy drives support only 64K byte writes, there's
no reason why emulation software on legacy drives cannot read
a 64K chunk, modify 2K of it, then write the 64K chunk back, to
emulate a 2K write. With intelligent caching, the performance
can even get better much better than this.

It'll be quite a while before I fully switch to Mt. Rainier
format if I know that my legacy CDRW drives are going to be
left in the dust as far as writing is concerned. Especially
if CDRW write speeds keep increasing (16x now) so format time
decreases even in old-UDF mode.

The price for progress...

Hi
You Say " Especially if CDRW write speeds keep increasing (16x now) so format time decreases even in old-UDF mode."

Some CD Writers including the Yamaha CRW-F1 have a CDRW Speed of 24x !!!

Yes we have tried F1 series with Mt. Rainier under Packet writing!

Wow 24x now. May be 48x within the next year. So, what's the
point of Mt. Rainier as far as the fast/background format is
concerned? CDRW media is probably being produced more and more
perfectly, so sector remapping may become irrelevant as well.
As an analogy, most of the 1.4 floppies these days never have
sector defects, so the ability to do direct diskcopy is the
norm rather than the exception.

Nasty situation just occurred for me using InCD on my Lite-on.
I had a CDRW disk formatted in Mt. Rainier, had data put on
it on that system, and transported the disk to a system with
a non-Mt. Rainier legacy drive. The InCD stuff proceeded to
load up the Mt. Rainier software reader so the disk is readable
on the second system. I switched off the MRW-format option in
InCD on the system with the Lite-on and put the Mt. Rainier
formatted disk back into the Lite-on. The system froze accessing
the CDRW drive. I switched on the MRW-format option after
rebooting, and the system still froze. I took the disk back to
the system with the legacy drive and the Mt. Rainier disk read
properly. Either InCD or the Lite-on drive firmware is pretty
screwed up... the hell with Mt. Rainier, at least for now.

LiteOn doesn't support Mt. Rainier accuratly yet. Check under Articles->EasyWrite article that says it all! [:p]

The point is the Yamaha CRW-F1E is 24x CDRW and it has Mt. Rainier so that should tell you something !!!
