4. In addition, recovering disk signature allows to recover VSS snapshots used by Windows Vista
and Windows 7's "Previous Versions" feature.
If the box is unselected, Acronis True Image Home generates a new disk signature for the recovered
drive. This may be needed when you use an image backup not for disaster recovery but for cloning
your Windows Vista hard drive to another one. Trying to boot Windows after cloning with both
drives connected will result in a problem. During Windows booting, its loader checks the disk
signatures of all the connected drives, and if it finds two identical disk signatures, the loader changes
the signature of the second disk, which would be the clone disk. Once this happens, the clone disk
would not be able to boot up independently of the original disk, because the MountedDevices fields
in the clone's registry reference the disk signature of the original disk, which will not be available if
the original disk is disconnected.
11.1.5 Selecting a target disk/partition
1. Select a target disk or partition where you want to recover the selected image. You can recover
data to its initial location, to another disk/partition or to an unallocated space. The target
partition should be at least the same size as the uncompressed image data.
All the data stored on the target partition will be replaced by the image data, so be careful and watch for
non-backed-up data that you might need.
2. When recovering an entire disk, the program will analyze the target disk structure to see
whether the disk is free.
If there are partitions on the target disk, you will be prompted by the confirmation window stating
that the destination disk contains partitions, perhaps with useful data.
You will have to select between:
OK – all existing partitions will be deleted and all their data will be lost.
Cancel – no existing partition will be deleted, discontinuing the recovery operation. You will then
have to cancel the operation or select another disk.
