Shankly that is why I suggested accessing another machine running Windows because obviously a drive on which Windows is running cannot clean itself using DISKPART and that process would be done via the other machine that is running Windows and as per Thrash Zones post #9 - you can right click on that partition and then click Explore it will let you know what those files are.

Windows 7 Home Premium 32 bit

I presume that the OP was trying to clean his boot drive running diskpartclean from the Windows 7 Installation Disk. By mistake he performed the diskpartclean on the second internal data drive.

( The OP seems to have completed the Windows 7 installation - though I would say it is far from perfect since the previous system reserved partition is still there as unallocated.He perhaps did not delete all the partitions before installing Windows 7. Perhaps ThrashZone/AddRAM/ICIT2 can guide him to do a perfect clean install after he recovers his second drive.And yes , before doing a Windows install it is always prudent to disconnect all other drives. Otherwise as many as three persons here have to crack their heads and crank Sevenforum servers :))

His problem now is how to get his second internal drive on which he has wrongly run diskpart clean back on track.

The current situation is though he ran Partition Recovery Wizard on Disk 2, he does not know how to complete it. :)

As I see from his screenshot, Partition Recovery Wizard has seen three partitions, he has selected all three and clicked on Finish on the Partition Recovery Wizard window. The operation is still pending. He has to complete it by clicking on APPLY in the Partition Wizard main menu bar on top. That will write the partition tables and complete the Partition Recovery. Then he has to right click on the main data partition of his Disk 2 in Partition Wizard and assign a drive letter to it. And that is it.

( At this point I have to say that it seems he had formatted his 1TB data drive as GPT and then had converted it to MBR. That would explain the 129 MB and 8MB partitions before and after the main partition. Not an issue but I am just wondering why he initialised it as a GPT drive in the first instance and later converted it into MBR)

Windows 10 Pro x64

Once again, this is where a Partition Wizard Boot CD comes in very handy, even if you still have other drives hooked up, Partition Wizard will only do what you you tell it to.

Everybody should have one, ok everyone give me your address and I`ll mail them out for Christmas
