My Passport Studio - 640GB Firewire - Use with Mac and PC

Hi

I have the following WD Passport:

My Passport Studio
Ultra-portable Hard Drives
640 GB, FireWire 800, USB 2.0

 

I am using it with my Mac Book Pro, which using Boot Camp, I have Snow Leopard and Windows 7 installed.

 

I can use my WD Passport when running Leopard but not when I’m running Windows 7, due to the Disk Format.

 

How can I reformat my WD Passport, so that I cnn use it with both Leopard and Windows 7 via the Firewire Port without any degregation of performance.

 

Can I format the drive directly from Windows 7 or Snow Leopard?

 

I plan to use the disc simply as Scratch Disc, for software I use on Windows and Mac.

 

Any help would be appreciated.

 

Cheers

You could partition it on the Mac using the FAT 32 Dos partitioning scheme.  But you will have a 4 GB file size limitation.
