I wanted to install another Linux on my computer, so I tried to resize one of my NTFS partitions with Norton Partition Magic. It didn't complete successfully, showed some errors, said that the partition is not resized and that it's the same size like before. But when I rebooted my computer I couldn't open that partition anymore and I am also not able to mount it from Linux.

So this is my question: I had very important data on that partition - can I recover it? I guess nothing's deleted; it's just something messed up so it's not usable, but can I get it back? Please reply if there's any possible way of doing this, thank you.
