CD burning finishes prematurely

i've got an ASUS 52 speed drive and was trying to burn an audio CD off the
hard drive at 40x onto a TDK Metallic CD-R80. however about a few minutes in
it decided that it was burning to an 'illegal medium' and stopped. the cd
still appears to work in my audio cd player until track 10 of 11 when it
can't cope. The computer has similar problems. any ideas why it happened.
this is the 2nd time it's happened although i've had no trouble with these
CDs before and the drive is only a
few months old. would the fact that the IDE cable is only a 40 wire one not
an 80 one cause this?

cheers
