Can someone help me interpret the following message:

cd0(pciide0:1:0):  Check Condition on CDB: 0x28 00 00 00 00 00 00 00 01 00
    SENSE KEY:  Blank Check
     ASC/ASCQ:  No Additional Sense Information

This showed up in the output of dmesg after I burned a CD.  Does this
mean that there is a problem with the drive, or the media?

I am running 1.6 on i386.
