Hello,
during some activities (e.g. erasing a CDRW or fixating a CDR on my
CD-Burner) the hard disc on the same cable cannot be accessed.All data and
swap partitions are inaccessable. There is no dmesg output, just entering the
mount point fails.
Other activities (like burning the track) does not cause this problem.
I use Cdrecord 1.11a13.
The problem occurs with 2.4.18 and 2.4.19pre3, that means with the new and
old ide-driver.
I have not included ATA-CD-Support in the kernel and instead compiled
ide-scsi as a module to use all my CD-drives with cdrecord. (see config below)
I am not sure if it is a kernel problem or if it is a firmware-bug.
Any idea?
Thank you.
Christian

Neither. Its an IDE design limitation. IDE can't handle disconnects like
real scsi does. The fixate command effectively locks the bus until it
completes.
There has been some movement forward in the standards on this. You might
want to ask our new 2.5 IDE maintainer if/when it will be implemented - I
suspect you have to wait a while though. There is much IDE to clean up first

Just for the record: I'm aware of it.

That doesn't say much about your plans for it though.

Good to hear that.
But I guess this is future work and will never get into 2.4, right?
Bytheway, as you became the IDE maintainer for 2.5, who is the IDE maintainer
for 2.4? Andre?
greetings

It is future work yes. I don't intend to care about 2.4. Since the 2.4 is
leaking the BIO stuff it will be quite hard to backport the IDE stuff if
someone (not me) attempts to.

Yes.

I'm still working with Andre on 2.4 stuff.
