I am running Windows 10 Pro and I cloned (disk-to-disk) my 120GB SSD drive to a larger 2TB SATA drive because I was running out of disk space on the 120GB. I used Clonezilla and everything finished successfully.

After cloning, I removed the 120GB SSD drive and booted from the 2TB SATA drive Windows loaded successfully, but in File Explorer, it show that the C: drive is still 120GB and the new 2TB is not shown.

In Disk Management however, the new drive is shown with 4 partitions: 100MB System Reserved, 120GB (C:), 450MB Recovery Partition and 1751GB Unallocated.

How can I increase the size of Drive C:?

  • @Damon - FYI, your link is bad. It has an extra "/ added to the end of it. – n8te Dec 04 '16 at 02:22

  • Since cloning does write the partition sector-by-sector to new disk, it also writes the old size. You can expand your partition in Disk Management Console to allocate the entire drive. – NetwOrchestration Dec 04 '16 at 12:06

The remaining GB (difference between 120gb and 2TB) of your hard drive are free and must be manually assigned to a new partition or assigned to drive C (Resize the partition)

You can do it manually. In Windows, go to Computer Management and Extend disk space. If you do not want to do it manually you can use applications like AOMEI Partition Assistant Standard, GParted, etc.

  • The extend volume menu is disabled. Maybe it's because I have the 450MB Recovery partition at the right side of (C:). How can I move this so that drive C and the un-allocated are beside each other – F0r3v3r-A-N00b Dec 04 '16 at 02:27

Your problem is not specific to Windows or Clonezilla. What happened is Clonezilla does not purely copy files, but copies partitions as clearly stated on the official Clonezilla page:

“Clonezilla is a partition and disk imaging/cloning program…”

So what happened is when you ran Clonezilla between the 120GB drive and the 2TB drive is Clonezilla literally copied the exact 120GB partition from your old drive to the new drive. This is very useful for doing disk imaging from one drive of the same exact size to another drive of the same size but—as you now can see—is not so great when copying data from a small drive to a larger drive.

So your choice now is to create a new partition with the extra space on the 2TB drive and use that. But if I were you, I would reformat and repartition that 2TB and use a pure file copying utility. I’m no Windows expert, but based on this PC World magazine article, EaseUS Todo Backup Free 9.2 seems to be a better tool for copying purely files from one drive to another.
