Benefits to merge disk partition

Traditional mechanical hard disk is much cheaper than before and it is very common to use a 2TB disk for home computer. To use the disk space more efficiently, many people create several volumes for different types of files. However, some people created too many drives without a label which makes it difficult to identify drive and locate files. If you want to decrease the number of drives, then merge partitions.

Another typical scenario is related to low disk space. The system C: drive and the volumes that are used for backup and database runs out of space in a certain time. If it happens, nobody likes to spend a long time to reinstall Windows or recreate partitions. By merging partitions, you can occupy free space from another drive and then this problem can be solved fast and easily.

How to merge partition D and C

The steps are the same to merge drive C and D in Windows 7, however, there is difference you should know.

C drive is valid

As you see, when merging C and D drive in Windows 7, if you select D as the destination drive, you’ll see an error “The system/boot volume only can be set as the destination.”

If you merge C drive into D, it’ll cause system unbootable, so this operation is disabled. To avoid incorrect operation that leads to boot failure, System Reserved partition cannot be merged.

Defect of merging volumes

It doesn’t matter if combine two data drives, but it is not a good idea to extend C drive by merging drive D. All files will be moved into C drive, so you won’t lose any data, but all Windows services and applications from D will stop working. If you want to expand the C drive, resize volume instead of merging.

No matter you resize volume or merge partitions in Windows 7, there is risk of losing data with unreliable program, because all related parameters of disk and drive should be modified correctly.
