Re: reading a CD-ROM quickly...

Nathan --

I'm opening the raw device; the whole media. I need the 2352 B blocks because I'm reading VCDs.

So, you're saying that there's probably nothing I can do to speed it up on my machine, but that it might go faster on other machines. That's what I needed to know... Thanks!

This type of thing is very drive dependent. It depends heavily on drive firmware, especially when bad blocks are encountered, when media is scratched, smudged, or imbalanced, etc.

I've been trying to patch up a Mac with a G3 accelerator board to be useful. The
last bootable Darwin CD is vintage 2000. The most recent off the web is unbootable
by this machine.

I used my wife's iBook to burn a cdr image of the Darwin 1.4.1 CD. A couple of points
on that item. When I download and mount the image using Mac OS X 10.1.3 I
get segmentation faults when I do a 'more' on some of the text files, such as the
Apple License... and gnutar gets errors as well. And given that it is a 'cdr' image,
I can just take the image to my PC and burn a copy with Adaptec CD corrupter.

Hence I used the iBook. Now when I place the CD in my vintage Darwin, I get
an error message out, which suggests, 'Accesses to "Apple" (partition 1) may be
slow due to a misaligned block boundary', I have to wonder what introduced such
a problem, as I've downloaded the image via the web, used the Apple supplied
unstuffit, and used the Apple supplied iBook CD burning software...

and of course it doesn't boot my vintage technology machine...
