Hi kowsihan and Welcome to The Forum.

I think what you need to do is make your 2 logical and the unallocated space into one primary partition. You can then split that into as many logical partitions as you care.

i have to fomat all these drives to make it as single partitions! is it?

I hesitate to offer help in this situation because if you format a partition then that data is gone/lost. In my opinion formatting partitions is not for the general user because it can cause complete loss of data.

If you wish to try this then you should take images of the existing drives first which means you need another HD.

Then you delete the partition to the right or left of the unallocated space so that you end up with a large contiguous unallocated space. Then allocate it all together and restore your image to it.

Hi kowsihan

Reason is only 4 primary partition are allowed and you already have ...
What you can do is as you have 2 logical drives ... you have to format these two drives ... then you can create 1 primary partition .. in which you can extend the drive by creating as many logical drives.
