Windows 7 Pro, ASUS B85M-E motherboard, 16GB RAM, one 256GB SSD program drive and one 1-TB HDD data drive.

Windows explorer shows a single D drive of about 900GB total.

Disk Management shows Disk-1 with total 931.39GB and the following:

one 800MB partition 

one smaller 300MB partition

two "D" partitions: first is 434.33GB and followed by 435.95GB

lastly a 60.03GB partition

 

1. Do I really need all three, small, partitions? 

     If not, how to have just a single partition on the HDD "D" drive?

 

2. How to merge these two D partitions into a single partition?

 

I have already backed up the entire drive to a flash.

Thanks!

I'm not sure how it's possible Windows would give the same drive letter for two different partitions on the same disk. Please provide a screenshot of Disk Management.

In the Upper Pane you can see there is one D: with a capacity of 870.28GB. In the lower pane you have two partitions labeled D: which are approx half of 870.28. 

 

The reason for this is because Disk 1 is Dynamic and you are spanning volumes. Two partitions acting as one partition. Why you have a Dynamic Disk like this I don't understand. This is not an optimal partition structure. In order to have one D: the best option would be to backup all the data on D: and then wipe Disk 1. Partition and format as a Basic Disk. 

 

Disk 1 has a 60GB Recovery Partition. I'm not sure what that is other than a factory reset partition but that is bigger than any I have seen. The 800MB and 300MB partitions are not necessary as far as I can tell.

 

I would disconnect Disk 1 from the power and data. Then boot to see if it affects your boot. If not then I would connect Disk 1 again, backup the data on D: and wipe the drive. When detaching the drive make sure to pull the power and ground yourself on bare metal of the case.

 

See the below link. The OP has a disk similar to yours. Dynamic with two G: volumes that are spanned.
