When instaled Partition magic 8 on windows 7 when i started it program something Fixed
I didn't think that the old program named "Partition Magic" was actually usable on Win7, but maybe the problem is strictly that it's out-of-date and unsupported by Symantec any longer. I certainly had trouble trying to use it with Win x64 two years ago and just looked for an alternative.
The equivalent program you really SHOULD be using instead is named
"Partition Wizard". You'll find it very very very very similar looking to "Partition Magic". Curious, to say the least.
Anyway it's free, modern, has been spiffed up over the past few years, supports modern large hard drives, and absolutely runs under Win7 both x86 and x64. It's very widely used and very highly regarded. Download and install it, and run it, and see what it makes of that unallocated/raw space on your drive.
Also you should download/burn
the ISO image for Partition Wizard standalone boot CD. This is a "safe" version to use, through which you can do everything you can when using the installed version under Win7 itself. But it also can do special things (e.g. to your C-partition) that cannot be performed while Windows is up and running, hence the standalone boot CD usage.
