Awsome, TestDisk also worked for me! I was trying to repair a micro SD card (I don't know what it haves exactly), well, so I opened PartitionMagic and got 110 error on disk 1, then I opened Windows Disks Manager to check drive numbers, my hard drive was disk0, and the micro SD card was disk1 so I clicked yes to fix the error, the program didn't opened because of other error, so I restarted my computer to assure everything was fine. First I saw a program whitout icon on the taskbar so I knew something bad happened, my second partition disappeared (D:), I entered Windows's Disks Manager again and the second partition appeared as unallocated. Then I entered Acronis Disk Director, there was both partitions (C: and D:) and plus the unallocated space corresponding to second partition (about 800 GB more than the physical disks really have) I've tried Acronis Recovery Expert but no luck, at leas I could explore the disk from Acronis, all my files were there. Then I start searching in Google and immediately found this thread, I tried TestDisk and the problem seems to be fixed (I hope there are no corrupted files, I can't check them one by one), I also passed Windows Scan Disk and there was no errors reported. Thanks a lot for the information, hope it helps more people.
