Paragon HDM 12 does not recognize one of my partitions

On my desktop PC running 64-bit Windows 7,

I have one hard drive with two equally sized partitions C: and D:; and a second hard drive with one partition J:

Windows Explorer shows all 3 partitions correctly:

And so does Computer Management:

And I've been reading and writing files to D: with no trouble.

BUT: HDM 12 does not recognize partition D:

Under backing up disks and partitions, HDM 12 shows it as an UNNAMED and UNALLOCATED partition (not as D)

Furthermore, HDM 12 thinks that the file system in D: is invalid, even though Windows Explorer has no trouble reading and writing files to it (see above).

And under "Which files and folders to back up," it doesn't show D: and its files and folders at all:

What's going on here?

Could either of these be the cause:

1. The "Smart Backup Wizard" found about four I/O errors, which I told it to ignore.

2. Prior to running HDM 12, I had run chkdsk on D: to check for errors, as follows: I selected D:, right-clicked on "Properties", then selected "Tools" to run error-checking on D: It told me I needed to dismount the drive temporarily, so I did. But I rebooted, and as you can see, D: is fine as far as Windows is concerned--but HDM 12 still can't see it.

Any ideas? I need to back up D: My hard drive is failing so I need to replace it and rebuild C: and D: on the new drive.

 

As variant: 1. Copy all files from D: (~26GB ?) to C: or J: in windows explorer
2: Delete all fake partitions on disk 0 in HDM or simply start wipe disk 0 and break shortly after the beginning of the operation
3: Create new D: partiion on disk 0 with HDM or with windows diskmgmt
It's all, now partition must be normal and files can return back

 

I'd say something is bad in the partition table but it could be elsewhere. Paragon and Windows likely use different methods of interpreting the disk structure and Paragon is not happy with what it is seeing.

Since you know the drive is failing, get the important files off the drive using Windows Explorer or some other method that works. You can then try using Disk Management to delete and re-create the partition but if the disk is bad, why bother - it's going to get worse, not better.

 

Use windows disk management to shrink the D partition a tiny bit.

Then extend it back with windows disk management.

Paragon will probabaly be fine with it then.

 

is the drive encrypted by chance?
