As a newly migrated Mac user, I tried to format my external HDD (40gb Cutie) which I have had for a few years. It was previously formatted in XP (fat32). I could load to my MBP (15" Rev D) but not from the MBP to the external HDD. So I tried reformatting using the beginners guide here. It went well until it hung-up. Since then the MBP and PCs do not recognise the external drive. Bringing up the Disk Utility I can see it but any attempt to use or format just has the MBP hang and I have to Force Quit. Any assitance would be appreciated.
