Partitioning

Is there a way to reallocate unused space from D drive to C drive without losing any data?

Hi! If the partitions are on the same disk, you can use Disk Management to shrink partition D and enlarge partition C.

You can try disk management, but it might fail.

If you use it to shrink D and end up with this:

C unallocated space D

Then you can likely use DM to expand C into the unallocated space.

But if the shrinking leads to this:


C D unallocated space


You probably will have to use a third party tool such as Partition Wizard to expand C into the unallocated space.

You should be able to shrink either C: or D: to create unallocated space and use Method One of this tutorial at the link below to create an Extended partition and then as many Logical drives as there are available drive letters, can then be created within the Extended to use as storage.


Partition / Extended : Logical Drives


One word of caution: if D: is labeled as a "Recovery" partition in Windows disk management, you do not want to destroy it by changing its structure in any way.

The very easiest way is to use Disk Management. Save your Data from D and delete the D volume. Then extend C as much as required and make a new D ( logical partition) from the leftover unallocated space. Then move your data back.

Any other method requires different programs because Disk Management can only extend C to an unallocated space directly adjacent to the right of it.

If you have no external disk to save the content of D and if you do not have 4 primary partitions, you can also do this: Shrink D and make a new partition (e.g. E) in the gained unallocated space. Then move the content of D to E. Now delete the D volume and extend C. Then you recreate D from the remaining freespace, move the data back, delete the E volume and extend the new D with that.

This will depend a bit on the amount of data on D and how much Disk Management will let you shrink D.

Ted, I think the OEMs finally got smart. They made the recovery partition a hidden partition and defined D as a data partition with nothing on it. Thus they avoid this constant problem where people made data backups (which assumes D as backup drive) without changing the drive letter thus messing up the recovery partition.

I have seen that setup on several new laptops from members at my computer club. The unfortunate thing though is that the OEMs made all prtitions primaries using the max. of 4 with that D partition (plus C, recovery and active 100MB). There was no need to do that, but they are slow learners.

I have used my first solution of the previous post on several machines to get the guys out of the 4 primary bind.

Well at least we have been able to counter every stupid move the OEMs make with a better method eh mate.

Please post back a screenshot of your full Disk Management drive map using Snipping Tool in Start Menu. We can give you the steps to Resize the partitions using free Partition Wizard bootable CD since Disk Mgmt cannot be used to Resize to the left.
