text: i have an hp laptop compter with a dvd drive.  when i put a blank disk in to copy picture files? the drive ejects my disk, says disk not blank, insert a blank disk.  i tried to use the kodak software and the hp software which came with my computer.  i am using cd's rather than dvd's.  at one timei was able to copy pictures to a cd. two choices come to mind:  1) you are putting the disks in upside down,,, 2) the disks are really not blank... are they perhaps "used" cd's?  if so, you can't re-write to them unless they are marked cdrw and you first "erase" them!  finally...  can you read any cd's?  if not, then the drive is broken and should be replaced... although reading does not necessarily mean it will also write, if it can't read then it definitely can't write!
