How to use a hard disk windows and Mac ?


I have a SATA hardisk drive in an external case (could be connected by USB), I would like use it under windows and Mac but as far as I know Mac can´t read NTFS and FAT32 can´t support partitions like 320Gb.

What can I do?

This should instruct you quickly how to accomplish this.

I also noticed that when I use my HDs they automatically work on both OSs.

Maybe it varies by brand as well.

The disk has to be formatted FAT32 to read under UNIX (MAC) and Windows.
Check out MacFuse.  Normally OSX can read ntfs it just cant write to it.  This software allows you to mount pretty much any file system within your mac.

Apparently the reason mac does not read NTFS is because MS wont release the specs.

but yes..  fat16 is like 2 gb max..  fat32 is 64 gigs i think.  Let me know how it works for you.. I plan on downloading it tonight and checking it with my 120 gig external.
Well, most likely the drive was formatted under the NTFS filesystem, for which Mac OS X has read-only capability. You can use the third party ntfs-3g driver to gain write access to your NTFS volume, but beware: it's still in beta and if you value your data I'd recommend having it backed up somewhere. That said, here is the howto:
