Fairly modern: 2.4.18. What do you mean by UDMA compatible? Do you mean
that they both should be UDMA (which they are) or that they should be
both UDMA of the same feather (which they aren't, UDMA 66 / 100)?
Again, my CD writer is fairly modern (it's a 16x10x40x drive). And it's
in the second channel? Any other ideas? Thx.
