Hi all, I've just installed Windows 8.1 onto my friend's laptop, a Sony Vaio. Originally, there are 2 partitions: C for Windows 8.1 (143GB) and D for Data (165GB). I decreased partition C to 43GB and increased D to 265 GB by using Acronis Disk Director Suite from Hiren's Boot CD. Unfortunately, the process crashed. Partition D's format became RAW and whenever I open it, what I see is "Disk structure is corrupt and unreadable". What can I do now? Somebody, please help me. Thank you very much.
