This is normal behavior if you boot Windows with both the source and the cloned drive attached

This article applies to:

• Acronis Migrate Easy 7.0
• Acronis True Image Home 2009
• Acronis True Image 11 Home
• Acronis True Image Echo Server for Windows
• Acronis True Image Echo Workstation
• Acronis True Image Echo Enterprise Server

Description

1. You clone your hard disk drive using any of the listed Acronis products;
2. After cloning, you boot the computer with both the source (old) drive and the cloned (new) drive plugged;
3. In Windows the cloned drive gets assigned a new letter, different from the source drive.

This is normal behavior. Windows will not reuse the partition letters from the source drive, if you boot with both the source and the cloned drive attached. Instead, it will assign new letters. If you do this, please redo the cloning. See also Cloning Laptop Hard Disk.

For this reason, it is strongly recommended to detach the source or the cloned drive from the computer before booting it.

More information

The described behavior does not depend on whether you clone in Windows or from Acronis Bootable Media.
