Could you provide some idea as to what you intend to do with the floppy disk. Are you trying to get the computer to recognize your new sata HD? I would check out this site anyway not sure exactly what process you are wanting. Hopefully this will be of assistance. http://www.wdc.com/wdsearch/search.aspx?sq=sata disk floppy instalaion files&sl=en-US&sc=
Once at this website if you will click on : wd sata hard drive Quick install guide

Good luck!
