I'd think OSX supports NTFS because *nix does and it's based off *nix.

I id check & my copy of XP has a format option for exFAT.

The syntax for a exFAT format is here.

My Win7 32 pro does not have it listed unless there is some trick method. Vista 64 does not have it listed however it does have FAT-32. XP has it listed ---ExFAT.

From memory OSX will read NTFS volumes but not write or format them.

For not much money MacDrive solves the problem of creating and working with HFS volumes.

I think on Windows 7 exFAT format option appears only when you try to format removable media, like USB flash drives. It doesn't show up when you try to format HDD.

Thanks.

I just formatted my second hard drive with exFAT. It works fine with hard drives.

"I just formatted my second hard drive with exFAT. It works fine with hard drives."

What is your OS?

When I tried to format my HDD in Windows 7 64 bit I only see NTFS.

You have to do the exFAT formatting from a command prompt window. At least that's how I did it. My machine is Windows 7 64bit.

Open a command prompt window, then type:

format (driveletter): /fs:exFAT

I just was discussing this with the guy who recommended it it to me tonight. He tells me that he has been doing this for a while because it lets him share drives between his Windows and Mac OS computers. I had never heard of this before his recommendation. He didn't want me to use FAT32 because of the sizes of some of the video files.

I recommend MacDrive. It allows your computer to read and write Mac Formatted drives. Makes like very easy when interchanging with Mac users.

+1 for MacDrive. I've been using it for several years to exchange files with FCP users and it's a great tool.

I think that MacDrive was a great product for it's day, but one that is no longer necessary.

I found this on FAT32 and exFAT:

Laurence, I disagree. Look at the caveats for both of those options. Won't work on older OS's, 4gig limitation, Mac Can't format.

MacDrive just works. Worth the $40.

The 4 gig limitation is only with FAT32. ExFAT can do whatever size NTFS can. Since I'm working on Windows 7, and the guy I'm exchanging files with has a brand new iMac, exFAT is going to work fine, and in fact be the better solution in our case. I suspect it would be for many other people as well.
