|I don't know macs anymore but that doesn't sound right. You may need to repost in the mac forum or someone else may post in and clear it up.|
In the meantime you can format it on your PC. As a matter of fact you can go into disk management and delete the partition. That will leave the entire drive as unallocated space and the mac shouldn't have a problem setting it up then--well assuming there's not some other reason why the mac isn't seeing it.
