Okay, maybe this is me worrying about nothing, but...
I have a 500 Gb. external drive where I want to create a second partition. I plug it into my Windows 7 box, use Disk Manager and pick the "Shrink Volume" option. It says that the maximum amount to shrink is around 150 Gb. I hit "OK" and it starts working... and it's been going on for about half an hour.
The light of the external HD is constantly working. Disk Manager is greyed out and has the "does not respond" message on the top bar; basically, it's behaving as a non-responding application.
Is this normal for a drive of this size, or did the application hang? How long would it typically take for a drive like this to resize its partition?
