I have CD-R's that are 6 yrs old or older and still readable.  But I've
had CD-RW's go bad in a year.  I don't use CD-RW's any more.

Don't know where I got the notion, but I could swear someone told me
that Sharpies were OK for CD's.  (I admit I can be a bit dyslexic at
times.  They may have told me NOT to use them.)  That said, I don't seem
to have had any trouble related to writing on CD's with them.  Some of
the better CD-R's have a writing surface on the back.  I wonder if that
makes a difference.

You mean I shouldn't be sniffing them?  :-)  Reminds me of an episode of
the animated Dilbert series where the "downsized" employees had been
shrunk and were living in Dilbert's desk.  These tiny people were
partying all the time, getting high off the fumes from "Dullie" brand
markers.  To get rid of them, Dilbert took away all their markers and
the poor little people were all having marker withdrawals.  :-)
