Volume properties
  Resizing and relocating  

When recovering a volume to a basic MBR disk, you can resize and relocate the volume by dragging it or its borders with a mouse or by entering corresponding values in the appropriate fields. Using this feature, you can redistribute the disk space between the volumes being recovered. In this case, you will have to recover the volume to be reduced first.

Tip: A volume cannot be resized when being recovered from a backup split into multiple removable media. To be able to resize the volume, copy all parts of the backup to a single location on a hard disk.


A basic MBR disk can contain up to four primary volumes or up to three primary volumes and multiple logical drives. By default, the program selects the original volume’s type. You can change this setting, if required.

  • Primary. Information about primary volumes is contained in the MBR partition table. Most operating systems can boot only from the primary volume of the first hard disk, but the number of primary volumes is limited.

    If you are going to recover a system volume to a basic MBR disk, select the Active check box. Active volume is used for loading an operating system. Choosing active for a volume without an installed operating system could prevent the machine from booting. You cannot set a logical drive or dynamic volume active.

  • Logical. Information about logical volumes is located not in the MBR, but in the extended partition table. The number of logical volumes on a disk is unlimited. A logical volume cannot be set as active. If you recover a system volume to another hard disk with its own volumes and operating system, you will most likely need only the data. In this case, you can recover the volume as logical to access the data only.
  File system  

Change the volume file system, if required. By default, the program selects the original volume’s file system. Acronis Backup & Recovery 10 can make the following file system conversions: FAT 16 -> FAT 32 and Ext2 -> Ext3. For volumes with other native file systems, this option is not available.

Assume you are going to recover a volume from an old, low-capacity FAT16 disk to a newer disk. FAT16 would not be effective and might even be impossible to set on the high-capacity hard disk. That’s because FAT16 supports volumes up to 4GB, so you will not be able to recover a 4GB FAT16 volume to a volume that exceeds that limit, without changing the file system. It would make sense here to change the file system from FAT16 to FAT32.

Older operating systems (MS-DOS, Windows 95 and Windows NT 3.x, 4.x) do not support FAT32 and will not be operable after you recover a volume and change its file system. These can be normally recovered on a FAT16 volume only.

  Logical drive letter (for Windows only)  

Assign a letter to the recovered volume. Select the desired letter from a drop-down list.

  • With the default AUTO selection, the first unused letter will be assigned to the volume.
  • If you select NO, no letter will be assigned to the recovered volume, hiding it from the OS.You should not assign letters to volumes that are inaccessible to Windows, such as to those other than FAT and NTFS.
