As long as you don't mind the explanation coming from another IDE
ignoramous. Actually this is a problem, in a milder state, that
people experience under native Windows when they start writing CDs,
which is a data flow critical process where it can be seen.
An ide controller typically has two channels and each channel can
service two devices. So, when you plug in a hard drive you connect a
cable from the controller to the drive. When you plug in a second
device (a CD device) you just plug it onto the same cable the HD is
connected two.
These controllers have some difficulties providing data flow from one
device to the other on the same channel. Normally this isn't a
problem as the flow is buffered and short little burps are handled
without problem. When writing to a CD writer, however, it just can't
handle those burps as its buffer empties and you get a bad CD
created. It's actually recommended under Windows that you install
your CD writer on one channel and devices you're going to write from
on the other.
Under Linux this hasn't been a problem either but something got a bit
bugged in v7.2 of LM and this streaming (from devices on the same
channel) tends to fail. Until the bug is fixed the solution seems to
be to read from one channel and write to the other. I don't know of
anyone who had this problem prior to 7.2 but it's a problem now.
Hope my attempt at a non-technical explanation helps.
