After discussion with Soren off list, I'm bringing this onlist :)
Machine:
K6/2-450 on Asus P5A with 128 Meg PC133 (runnin 100) ram, Western Digital
Caviar AC23400L 4.3 gig, Sony DDU220E dvd rom
OS:
FreeBSD 3.x-STABLE for much time, switch to 4.0-CURRENT ~month and a half
ago?, been updating and building/installing worlds now and again since
Problem:
Drive does not support (or claims to not support) the LBA access
methods. I'm not certain if there's some little tweak that's wrong in the
bios, or if the acd driver's confused, or if the drivey (Sony
DDU220E) generally hates LBA. Problem _did not exist_ under 3.x-STABLE
that I recall. (read as, maybe somone should point me to how to debug this
really low level ;)
Specifically, I could go into cdcontrol and attempt to play by block,
track, disk in general, etc. and it would fail with an i/o error in the
program, and a PLAY_BIG -- ILLEGAL REQUEST on console. WHen forcing it to
play by the MSF methods (specify the Minute Second and Frame to start and
end with) it worked. Further, I did a hack in atapi-cd.c to translate the
lba PLAYBLOCKS (I think) to translate to MSF and use PLAY_MSF
instead..... That, too, worked.
Three things)
1) Soren or some other highly educated person, can you give me a hand
(read as: give me insight into where to look) to see where the lba would
be failing so that it might be fixed
2) If one fails (which I don't see as happening since the drive worked
under 3.x-Stable just fine ;), it would be really nice if the kernel would
handle this and say, 'Oh, he wants to use LBA playing methods which won't
work on an MSF drive... We need to translate and call the MSF.' I don't
like this, and I take from the sound of it, Soren didn't either (he
mentioned that there wasn't a real good soloution).
3) If cdcontrol allows switching from msf (default) to lba can we have
this better documented.... I don't really know what this switches
between. I certainly _want_ cdcontrol to play MSF since it can't LBA, but
this doesn't do that.
(Note: The reason I suggest having the kernel do the translation to MSF is
that it's not going to be easy/possible to ask every program to check it
themselves ***sigh***)
