Real case about "Clone hard drive with different size"

“owing to some reasons, I cloned my1 TB hard drive to a new SSD. However, the cloned SSD has different size. And my drive only has 157GB used space. It makes me confused. Is there any way to clone hard drive of different size?”

In this case, you may want to replace HDD with SSD. Before that, you need to get the common issues of disk clone.

1. In most cases, the logical sector size of HDD is 512 while the logical size of SSD is 4096. Then, a question come out: how to clone hard drive with different logical sector size? You just need a smart disk cloning tool.

2. SSD disk is smaller than HDD in most situations. It's a little tricky for users to clone large HDD to smaller SSD, because there are a few disk cloning software can do that. Many users report that they only use a part of the space. Thus, you need a magic disk cloning software which can only clone the used space on the original hard drive.

3. Unallocated space after cloning smaller disk to larger disk. In general, after you clone HDD to larger SSD, the space out of small disk will be marked as unallocated space. Disk Management only shows the cloned part. For example, if you clone 130 GB to 500GB, then the 500GB hard drive shows only 130GB of space in the Disk Management and the extra space will show as unallocated space. So, you need to adjust the partition size with disk cloning software.
