Mount Rainier for Linux

    The Mount Rainier standard sounds nifty, even if the technology is still a couple of years out of wide consumer usage. But my only beef is this: does current CD-R(W) burning software for any platform have to be more complicated than the average computer user can handle?

    Enter Apple's little-known Disc Burner software, and the Authoring Support software located under the hood in the system folder. The basic premise? Put a blank CD in and Disc Burner asks for a format (either hybrid ISO/HFS, Audio, or just plain vanilla ISO), and voila, on your desktop, is an icon of your CD. Drag-n-Drop to your heart's content, and then select "Burn CD" from the Special menu (or drag the CD to the trash, then asking you to burn the CD. Even I never have understood the user interface issues with dragging a disk to the trash to eject it). Done. Simple. My cat can even burn CDs now.

    The moral of the story? Mount Rainier will be an easily applied standard across all platforms. But who said the current technology's software had to be difficult? Granted, Disc Burner is not Mount Rainier, but it definitely is a current and usable facsimile of the technology.

    TiVos are linux based, definitely consumer-oriented, and probably have one of the best user interfaces I've ever come across. They're also getting close to critical mass in terms of users, I figure.

    Mod me down if you like but Windows XP has this basic capability built in and every one thinks its a bad thing....

    Here is what happens when i insert a blank CDR in the disc drive.

    Windows can perform the same action each time you insert a disk or connect a device with this kind of file:

    blank CD

    What do you want windows to do

    1 Open writable CD folder using Windows explorer

    2 take no action

    Select if you want a default action to occur

    Personally I dont use the built in software because I have other hapits but just to see if it could work I created a shortcut to the CDDRIVE and placed the shortcut on the desktop then dragged and dropped music files to the shortcut and lo and behold they were waiting to be burned. To do the actual burning I opened the shortcut and selected write these files to CD.

    bobs your uncle

    Now on to CDRW if the media costs come down and preformatted disks are cheap and they dont damage easily then I would probably use more of them. My own experience is they dont hold up as well to general everyday use...

    OK, Mount Rainier [] is a hardware command specification, not a file format. Mt. Rainier is geared towards the UDF file format, but other file formats could be used. The key point was, that Mt. Rainier would allow the OS to see a MR CD-RW as a block-addressable (rather than a packet-addressable) device. An OS can just write a file system onto a MR CD-RW on the dics without having to worry about packet sizes or bad-block mapping.

    The big point here really is: This would have created a lucrative business for Mount Rainier licensees in selling preformatted MR media

    So in any case, any OS could have operated on MT CD-RW (as far as I understood that), but it was the formatting that was blocked.

    Hope that helps,

    The point about Mt. Rainier is that it move defect management and other things into the hardware, rather than having software handle it. It essentially turns the CD-RW into a kind of harddisk, which also does its own defect mgmt.

    What about the fact that Philips (jointly with other companies) developed the CD-audio standard that we all know and love - for the entire industry instead of just for themselves. They have a pretty good track record of not being patent whores.

    BTW, everyone keeps spelling it 'Phillips'. There is only one 'L'.

    This type of CD-R/RW usage has been available (in Windows) for years via third-party software like Adaptec/Roxio's DirectCD or the NTI's FileCD and so on. CD players already support packet writing! Why is Microsoft, IBM et. al. taking about reengineering the CD from at such a low level? Doesn't it just require someone to write a Linux version of DirectCD/FileCD? Why can't we just format CD-R/RW discs with the UDF file system that DVD's already use instead of inventing a brand new one?

    Also, I'm not sure I even like the idea of this becoming the "default" behavior for CD writers. I strongly dislike the overhead involved in formatting. I find that a packet writing CD-R/RW hold about 100MB less. I'd rather have the full capacity. I mean, if you are using this thing for business backup (which seems to be the primary argument for needing Linux support) then you are only going to be burning once a day, so why not just burn a full 650/700MB worth of data as a single data track?

    This sounds a lot like the basic concepts behind Flash Translation Layer - you take a pile of sectors that are slow to erase, and insert a layer that allows you to map logical sectors to physical sectors any way you want. Thus, when you need to "erase" or "re-write" a logical sector, you just change the mapping to a physical sector that hasn't been written to. You then do a background process of taking physical sectors that are "dirty" (written to) but unused and erase them.

    Funny how this idea comes around - FTL, LVM, and now Mt. Rainier. Similar concepts, different applications.

    Look for example at IBM, they nearly died from getting not enough money from their invention of the IBM PC.

    Whereas Apple maintained a stranglehold on their hardware to keep it out of the hands of cloners and now command an impression 5-10% of the computer market.

    But I think its the only way that Phillips can hope to compete with DVD-R, DVD-RW or whatever ;)

    Which they already own for about 50%.

May all your PUSHes be POPped.
