Yes. Download UBCD and run KillDisk or some other low level wiping tool to completely wipe out the drive. Then format it via OSX.
Link:http://www.killdisk.com/Warning: Do be careful when running HDD wiping tools. To be safe, unplug all other HDDs, both internal and external HDDs/Flash,etc. If you choose the wrong HDD, your data is history
Alternatively, you should be able to format the HDD to FAT using a Linux Live CD.
