When need the hard drive cloning software?

As its name implies, the hard drive cloning software is a tool used to copy a hard drive (SSD, HDD, USB flash drive, SD card, etc) to another storage media, through which you can migrate all contents from one location to another different one. So, the hard drive cloning program is necessay whenever you need to clone a disk for any one of the following purposes.

  • Back up and protect vital data: Many accidents might lead to data loss when you use your computer. With the hard drive duplicated beforehand, you can get back crucial data when the original disk fails.

  • Replace old hard drive with a new one: With the usage of your hard drive, you may feel that your hard drive is too old to function well. Thus, you need to change your old hard drive to a new one.

  • Upgrade HDD to SSD: It’s well known that SSD (solid state drive) has better properties than HDD (hard disk drive). So, more users would like to clone HDD to SSD for a upgrade.

What is the best disk cloning software?

There are many species of hard drive cloning software available for your choice. But finding out the best one is a challenging task. If you have no idea, the free AOMEI Partition Assistant Standard is a wise choice. It has the following advantages to make disk clone easy and effective:

“Sector-by-Sector Clone” method: copy all sectors (used and unused) from one disk to another, allowing you to clone BitLocker hard drive, or clone hard drive with bad sectors.

“Clone Disk Quickly” method: copy only used sectors to the destination disk so that you can clone a larger disk to a smaller disk as long as the destination disk has enough space to hold used sectors on the original disk.

Flexible MBR and GPT data disk clone: clone MBR or GPT-based data disk to another MBR or GPT hard drive. If the GPT has less than 3 primary partitions, the freeware will clone GPT hard drive to MBR hard drive directly without converting MBR disk to GPT. If the GPT hard drive has more than 3 primary partitions, the primary partitions beyond the third partition will be converted to logical partitions.

Clone some special partitons like recovery partition: recovery partition is important and can be used to restore the damaged system in a few minutes when your system crashes. However, this partition always occupied a lot of space of local hard drive. So, you might want to clone recovery partition to external hard drive and delete the original one to release disk space.

Clone a specific partition: this freeware allows you to clone partition to another drive. If the partition you are going to clone is system boot partition, the “Migrate OS to SSD Wizard” is more recommended.
