Hi Guys,
I just reformatted my external 1TB WD hdd using my new macbooks disk utility and usb 3.0. I reformatted it to Exfat, so I could use it on both mac and windows machines.
Whilst it registers great on the mac, when I plug it into the windows 7 laptop, although its in the devices, it isn't appearing in My computer as a device connected. Not sure if there is a compatibility issue between usb 3 and usb 2?
Can someone please point me in the right direction, it is a little bit frustrating.

Kind Regards,
Ruby

If you right click on My Computer, goto Manage, goto Disk Management, do you see your drive within? If you right click on it, is there an initialize/import or similar command available?

For whatever reason, if you format exFAT on a Mac, it won't read on a PC.
If you format exFAT on a PC, the it will work on both.

By default, the OSX disk utility creates a new partition as GUID. Windows can't read it. You need to create the partition type as MBR, which Windows can read. Then format as exFAT and both machines will read it.
I hope this helps somebody!
