I have installed Windows 7 right after it has been released. Also, I have installed all the necessary applications on my computer, too. A few days ago, I have bought a new computer. As known to many users, installing the operating system and the applications will cost a lot of time. And, I want to copy the system drive to another drive. But simple operations of "Copy" and "Paste" cannot complete the operations of operating system and application migration. How do I copy a hard drive to another? Any suggestions will be appreciated.

In this cas, you can search free disk cloning software on the internet and use it to copy one hard drive to another. The majority of software can help you copy or clone disk to larger disk.


No matter what operation you want to do, there is always a cause. How to copy one hard drive onto another is not exception. Here, I'll list some possible causes in the following.

1. To prevent data loss. If your hard drive contains important files or folders, you may want to copy entire data from one hard drive to another. So if you delete any of them mistakenly, you still have a copy of files or folders.

2. To avoid boot failure or reinstalling Windows. In Windows, there are some special partitions are protected or locked by the operating system, such as hidden partition, system reserved partition, recovery partition etc. Thus, you cannot copy everything from one hard drive to another and use it to boot your computer successfully.

3. To upgrade disk to SSD for a greater perfoemance. In order to play games more smoothly, some game enthusiasts want a greater performance. On the market, there are two common disk, including HDD and SSD. HDD offers you a greater capacity as well as low cost while SSD offers you a faster reading and writting speed, boot time, etc. Thus, it's wise to clone hard drive to SSD with a disk copying software.

4. To copy one hard drive to larger HDD or SSD. Every hard drive is likely to be in a low disk space with the increasing files or folders. Thus, a new hard drive with a great capacity is needed.
