I have 2 hard disks in my system, both Hitachi. I formatted the 160 GB HDD but now its showing other (1 TB HDD) as "Dynamic disk" and data is unaccessible. Partitions are not being shown either. I don't to convert it because that will erase the data. It had ~800 GB data. What to do now?

I once used the approach described here

Convert Dynamic Disk back to Basic Disk without data loss

The idea is to modify MBR, to more precise partition's identified aka descriptor. But, prior to making changes I would try it on a test drive.

Hey thanks, I'll try that. What do you mean try on a test drive? –  Nix Nov 11 '12 at 17:19
    
Well, before doing this on production machine, first of all I went through the entire process on a test virtual machine which had dynamic volume. Just be very careful while editing MBR. If questions appear, you can post them back here. –  Volodymyr Nov 11 '12 at 17:26
    
Thanks, that's helpful. I'll arrange VMware and test it first. I really can't afford to loose that data :'( –  Nix Nov 11 '12 at 17:39
    
Hey,I forgot to metion this, but I am getting another option - "import foreign disks". Will it erase delete partitions or delete data? Screenshot - prntscr.com/jhqio –  Nix Nov 11 '12 at 18:58
    
There should be no problems with importing foreign disks according to Microsoft –  Volodymyr Nov 11 '12 at 19:13
