3TB interrnal drive with 3 partitions is unallocated

When I booted Win7 ran a CHKDSK on one of the partitions on the 3TB drive. When I got back into Windows drives G,J, and K had disappeared. DIsak Manager shows the drive as 27984.39GB Unallocated.

I found this forum and did some reading. I downloaded MiniTool Partition Wizard and it shows the following:



Please help

He may see your post and reply. If not, you might make a new post in the backup and restore section.

Partition Wizard is a good tool. I'd at least start by letting it do a full scan of the problem drive, but don't proceed beyond the full scan without assistance.

If you are lucky, you will be able to recover the partitions, which will still have the data files intact.

If you are not lucky, the partitions may be lost and you would then be forced to attempt to recover the files directly with some other tool.

Hi icr,

I know that you checked just four hours ago.:)

From the PW screenshot you posted I see that you seem to have lost your first partition. Partitiion Recovery Wizard did not find it. But it did find the second and third partition.

1. It is inconceivable that your HDD got corrupted just because you ran disk check. You ran checkdisk because you had a problem. What was it?

2. What prompted you or made you think that running checkdisk will resolve that problem?

3. Did checkdisk complete?

Though this is not going to resolve the issue, it will help us know the status of the disk at that time and whether running checkdisk on that problem had made it worse to the current situation.

I have my own doubts whether Partition Recovery Wizard is going to help in this case.

We haven't had any GPT disks on which we had run Partition Recovery Wizard. All the same we shall run it again but not before I examine some crucial sectors in the drive and backup those so that we can revert back should the condition of the disk become worse.

But that after you answer the queries above.

I would also like you to post a screenshot of Windows Disk Management. ( Please remove any USB drives from your PC. )

I don't think so but given that its going to be easy to plug out other secondary drives leaving only the system drive and the problem drive, do you think the OP should do it? You may instruct the OP so. It is a custom-built PC and so the OP should be able to do it easily.

I am retiring now.

There is no one-size fits all in data Recovery.

But the highly rated from our experience here are TestDisk, PhotoRec (free) and Getdataback for NTFS (paid) not counting partition recovery as data recovery software.
