Recover Space from MBR?

I was formatting my 500 GB Drive with DBAN, then it froze about 20% through. So I installed Vista, it thinks my HDD is 200 GB. I don’t want to format it anymore, I have Vista all set up now. Is there any way to recover those 250 GB from MBR?
Answer #1
check if it’s portioned with a 200gb size, maybe there are 250gb un-partitioned and not being used
Answer #2
How would I do that?
Answer #3
use partition magic it should show you unalocatd space then expand your existing partion to include the unalocated or to set up another partion using the unalocated space
Answer #4
Partition Magic doesn’t work with Vista.
However, Vista has it’s own partition manager. I tried it, and it doesn’t show up as unallocated space.
Answer #5
Not quite sure whats going on, BUT, GetDataBack for NTFS by Runtime Software has been a life saver for me in terms of data recovery.
I cant remember if its free, but i probably got it from here anyway
Answer #6
Use Hiren’s BootCD for Partition Magic or GParted Live CD …. both have partition tools ……. just BOOT from CD
Answer #7
try to use acronis disk director suite 10… it can create and delete partition without destroy the files in other partitions.
