cdrecording status

[Jan Engelhardt]

Hello list,


an info for the enthusiastic:

I have played a little with my new cd/dvd/whatnot writer and just had this 
idea (see pic). Well then, DVD+RW makes it possible.

The worst thing is not the atime update (as cdrecord-prodvd manual says), but 
the initial mount / log replay which seeks a lot more.

Commands used were:
  cdrecord-prodvd -dev=/dev/hdc -format -v
  mkreiserfs -f /dev/hdc
(Looks like the =/dev/hdc method works best (besides =ATAPI:x,y,z or 
=ATA:x,y,z), even though cdrecord bleaks about it.)

And the question aside: is writing CD-RW in packet mode also supported in 2.6, 
like DVD+RW is?

Just wondering: how many write cycles do DVD+RW media support?

Honestly I do not know, but I hope they can at least sustain as much as CD-RW 
can (usually 1000x). Plus, it's for DVD+RW, it always uses packet mode, and as 
such I damn hope that DVD+RW manufacturers keep in mind that a byte position 
might be overwritten more than 1000 times.

Isn't that what DVD-RAM is for?  IIRC, it's overwrite count is 100,000.

Now that's "just" 100 times more than a CD/DVD. However, the buffer cache is a 
really nice thing to have -- especially on such media.
