For the past five days I've been trying to get my new WD Elements portable HD to work with my new MacBook Pro. I am using Disk Utility to partition the HD (being 1 TB in size). However, this process is taking 3 days now and nothing seems to happen. The progress bar in disk utility seems to be stuck halfway but the program itself is still active. When I stop the process (by quitting disk utility) nothing happens. The program shuts down but the HD is nog longer visible in both Mac OSX Lion and in Windows. It is still there as disk utility does list it in the connected drives list - but it simply doesn't format it. At first I thought it was the disk itself so I got a new HD (and sent the old one back) but that hasn't solved the problem. Obvious question is: what's going wrong and how can I fix it?
