Disklavier

I am not a computer wiz and I have this problem of mine regarding 
720k floppy Disk. I am from the Philippines and Double density disk 
is not available here in our country. But I have found used DD Disk 
that I can use, the problem is that some of them can't be read by my 
Disklavier.I checked with my computer and an error says " can't 
read,no CRC" Is there a program to check the integrity of a 720K Disk 
and can I format it with Windows Format Disk? Thanks for any help you 
can provide.
