User case: Acronis computer restart is required

“I got a new SSD from Western digital and then downloaded the cloning software from their website, but this software always tell me ”Acronis computer restart is required” Whenever I try to clone hard drive with it. But it still does not clone my hard drive after restarting. Why Acronis WD clone failed? Is it possible to fix it? If not, is there any alternative disk cloning software?”

Why Will Acronis True Image WD edition not clone?

Here are some issues related to Acronis True Image WD edition you may encounter.

1. Acronis True Image WD edition fails to clone hard drive when the system indicates a reboot required. When you try to clone a hard drive with it, computer restart is required. However, your computer may not reboot.

Explain: you enable the secure boot in BIOS. And the secure boot does not allow this boot path as part of the cloning process. It's a security measure built into a system's BIOS, which is used to prevent untrustworthy firmware from running. To clone disk, you should turn off secure boot at first.

2. Acronis True Image WD edition does not recognize a Western Digital drive. Acronis True Image WD edition does not support exFAT file system, so Acronis won’t recognize it and you cannot use hard drive formatted as ExFAT as target drive. And most of the modern digital drive is formatted with exFAT. So, you need a better disk cloning software.

Explain: the most probable cause is that the drive does not have a valid MBR or a third party software is blocking the access to hard disk drives.

3. Don’t clone hard drive within Windows. When you start cloning in Windows, the computer may boot in to recovery environment. And there is a possibility that the hard drives are detected in Windows and not detected in recovery environment. In this case, the cloning process may fail after reboot.
