The expensive alignment disks you get from companies like Accurite are quite special and not written with any standard PC drive, hence you can't copy them and retain the special patterns they contain.
If you have one, try copying it, then put it in a drive you have hooked up to an oscilloscope and compare the patterns to the original.
