“I have an old Kingston 64GB SSD drive that contains my OS and programs. I try to clone it to a new OCZ Certex3 120GB SSD drive with Macrium Reflect free version. The cloning process goes smoothly but my computer won’t boot properly after I change the drive letter of old drive and boot from new SSD. I just want to keep the old drive and rename it with a different drive letter. What should I do? ”

For this issue, you need to make sure that the new SSD is a primary partition and marked as active. Also, you need to set boot priority for new SSD in BIOS. Then, take out the old SSD and boot from it. If your computer boot as normal, you can plug the old drive into the computer again.

To clone partition with free software, your reasons may be either a better performance, bigger capacity, or disk failure.

To achieve this goal, you can try to clone disk with a free disk partition cloning software and then switch out the old drive.

Today, I'll introduce you a freeware called AOMEI Backupper Standard. It can help you clone disk. But it's not limited to that only.

Free disk partition cloning software

As mentioned above, AOMEI Backupper Standard can help you clone disk. At the same time, it still can clone partition and clone system. These are the major cloning function in this software.

In general, a large number of software on the internet can help you clone disk to disk of the same or larger size. Unfortunately, a few software allow you to clone larger drive to smaller drive. In AOMEI Backkupper, you can clone to smaller disk as long as the used space on the old hard drive is smaller than or equal to new SSD.

Besides, it offers you 3 useful features for the cloning process.

1. Edit partitions on the destination disk. Many users may think the cloned hard drive show wrong size, because most of cloning programs will leave an unallocated space after cloning to larger disk and you cannot see it in Windows File Explorer.

To fix it, you can click this option and select Add unused space to all partitions. Or you can use a partition manager like AOMEI Partition Assistant to resize partition.

2. Sector by sector clone. This option is suitable for user who wants to clone disk to disk with the same or larger size. It will clone all sectors on the disk whether used or not.

If you want to clone to a larger disk, do not tick this option.

3. Align partition to optimize for SSD. This option is designed for SSD disk. It can improve the performance of your disk and extend the life of the disk.
