What do these warnings mean (re cdrom)?
I have a cdrom on /dev/hdd. My system sees it but doesn't see any disk I put
in it, either data or audio. I ran "cdrecord dev=ATAPI -scanbus" and got the
following output. I'm wondering about the NO DMA and the warning about the
controller returning the wrong size. Could either of these things be my

I this a cd burner?

No, just a plain cdrom. My burner is on /hdc.

i don't think those warning mean anything accept are a reflection of a scism between the cdrecord developer and the kernel developers

it's like they argue thru error and warning messages

if it's not a cd burner they certaily don't mean anything at all

Problem solved!
It was a bad drive. Replaced it. Everything works. Thanks for your help.
