Bad CRC error when creating FlashBIOS disk...

I'm trying to update one of our PowerEdge 1300 servers with the PowerEdge 1300, A11 update. I downloaded the B2756E11.exe file, but when I insert the floppy disk into the drive, and the program tries to copy the files to the disk, I get a "Bad CRC" error. I've tried this with several disks and I'm wondering how I go about correcting the problem.

Thanks in advance for your help with this matter.
