Issues with hard drives after recovery

[Eamon Bayle]

Hello forumers ! This is my first post.
I'm quite desesperate by some issues that occurred today.

There's a problem with a computer with Windows 8.1 in it. This desktop computer have 3 hard drives in it.
The main disk, with a partition with a recovery (Win 7) and the operating system.
2nd disk of 1.5 Tb, back in Win 8, 400 Gb was free space.
3rd another one of 500 Gb, with 500 Gb of free space.

The problem is, after seeing that we cannot use Inventor 2012 in Windows 8 OS, we decided to format the computer via recovery manager to put it back to factory values. After this, the main disk has the Win 7, but now, the second disk is detected and accessible, but it says that the capacity is only 400 (the 400 that was free before).
And the 3rd is undetectable.

Using Speccy software, seems that the disks appears as connected and with the original size, but Windows 7 don't, and we are in fear to have lost all the data.

Anyone knows what happen here?

Thanks a lot !

Check in disk management to make sure a drive letter is assigned to it. Right click on computer, click manage, click on disk management on left.

Well we did a disk management

The new information is that, the 1,5 Tb is the one that is not recognized (second disk). We confused the third 500Gb disk with the second.
So third is recognized and empty as it was, but the 1,5 Tb is not. Is where all the data is.

Here's a screen attached.

THanks in advance!

Looks like the 1.5tb drive just needs a drive letter assigned. However, currently it isn't formatted according to disk management. My guess is that there may be errors on the drive. The 500 gb drive shows its empty, but it is formatted as ntfs. What brand of drive is the 1.5 tb?

Don't really know the brand :/ ...

We got a copy of linux on a live USB pen drive, and this one detects all hard disks except the 1,5 TB.
1,5 TB HD is not even detected by the live distribution.... What can we do?
