Unallocated space - not able to extend current partition

[foreverinsane]

Hello,

 

I have a 1TB external HDD and need 3 partitions. 1 is a media partition with music, films ect, 1 a backup and 1 with other important files (such as family pictures ect).

 

The media partition is the biggest, but I wish to extend it with unallocated space. I have tried doing it with W7 but I get a similar error with Vista (on a laptop).

 

Any idea whats wrong or what I need to do?

The media partition is the WD Elements 1TB partiton on disk 1. I am administrator and have also tried in safe mode.

 

Any help is appreciated, thank you.

I would try a partition tool : GParted Live CD http://gparted.sourceforge.net/larry/livecd/livecd.htm

Thanks. Took a bit of getting used to - but this is certainly better. I also found out (via google) that unallocated space has to be next to the partition you want to merge it with - which makes sense :D.

 

This program helped a lot, thank you. :)
