I shrunk my external drive to use a portion of it for downloads but now it will only allow me to format 2TB and the 768GB is wasted. How do i get it to merge the unallocated space again? I deleted all the volumes but it refuses to include the 768GB back into the disk.
I seem to remember that 32 bit OSs can't address more than 2 TBs of anything, be it RAM or Hard Drive space.
If you indeed have a 32 bit OS, you might want to look into this as the potential cause of your problems.
I figured it out about 5 minutes after makeing the post, thanks for the help though. I was unaware of the new file system in use by 3TB drives until now, i was wondering how they fixed the issue with them.

Both 32bit Viata and 7 have gpt support, so they can use drives larger than 2 TiB.
