I have a 250 GB SATA hard disk, that was partitioned as follows:

  • C: - 60 GB
  • E: - 40 GB
  • F: - 40 GB
  • G: - 45 GB
  • H: - 45 GB

However, only C: is visible in My Computer now. All other partitions are missing.

When I open the Disk Management window, it shows a 170 GB RAW healthy logical drive.

Can I recover my drives without losing my files?

I have 2 question: 1.Have you formatted the disk? 2. Whate are filesystem of those partition ? – user144565 Sep 16 '12 at 11:05
    
Have you been messing with the disk's partition table? There is a lot of useful software that can help you rollback the changes. Take a look at this one. partition-recovery.com I haven't tried it but it's freeware. – Yaroze Sep 16 '12 at 13:14
    
Did the drive 'go missing' in the running machine or did you move it to another machien? Had you been using any recovery/maintenance software shortly before this happened? – Jan Doggen Sep 16 '12 at 19:01
    
Is it possibly hidden? When you open My Computer, and type "F:" in the location bar, do you see the files? – dangowans Sep 19 '12 at 20:29

Try using the free version of Partition Find and Mount on the drive. If it works, there's also a commercial version which is useful if you have a significant number of folders and files to recover.

If you have to create a volume on the drive first, make sure you use the Quick Format option to minimize the loss of data still on it.
