Windows 10: Can I recover an unallocated disk's data after a clean Windows install

Hi all! Need halp!I successfully ran a clean Windows 10 install from a flash drive. In my previous setup, I had a separate drive as my Desktop location D: which held my day to day files and photos etc. The idea being that all my apps and OS live on C: and D: would be my working drive which I didn't backup because unplugged it to protect it and avoid overwriting it.However when I plugged D: back in after the install, its now showing up as Disk 1 Unallocated! In my research I can't seem to find a way to recover this volume without losing the data. I can't even run a messy recovery because th

Recovering "unallocated" data

I had a RAID 1 set up and installed a few new components in the system. Then the BIOS changed SATA mode to AHCI for some f*****g reason, and my disks fell out of the array. So I tried simply setting it back to RAID and re-creating the array, but now they just show up as unallocated data in the disk manager.

I do have a backup, but it's a week old, and I'd prefer not to lose the new data. Is there any way of retrieving it?

Hi,DawnWilliams8

Based on your concern is how to recover the unallocated partition, so that why

I provided the details on how to recover the partition, probably after you recover the unallocated partition that's the time you can work you 3 partition.

If that won't work will ask for another expert about their suggestion.

Recover unallocated space on data disk

Woa! Doing as you say in Case 2 would delete the Windows partition and make system unbootable! Thankfully Windows won't let you do anything on the system partition from Disk Management.

Case 2: If the empty space is on the left (unlikely), then use a partitioning utility such as MiniTool Partition Wizard Home Edition to move the large partition at the start of the disk and then extend it to take all disk.

But if we are talking about 350MB (MEGAbytes, not GIGAbytes), then this is too small by today's standards to bother. Moving all data to the start of the disk involves copying all data and as you can imagine it will take all day! Too trouble for nothing... I would just ignore it. On the other hand, if you are at case 1 (unallocated space on the right), then it will take a few seconds to extend the large partition to take all disk, as there is no need to move any data.
