Cloning a Partition

Cloning a Partition

If you have chosen to clone a partition, you are said to be in "Partition Mode". You are going to copy a single partition sector-by-sector from an existing hard drive. You will have control over some parameters of the operation. You may write the clone data to an existing partition (by overwriting it) or to unallocated space, provided that the target is large enough.

Exclusive access to the target

If the selected target is not unallocated space, Active@ Disk Image must have exclusive access to the target partition while writing the clone data. Before you confirm the details of the operation, Active@ Disk Image attempts to lock the target partition for exclusive access. If another application or the operating system is using the target partition, you must close all applications or system processes that may be using the target partition.

If you cannot lock the target partition after closing applications and system processes, there are other alternatives that you may try:

  • Choose a different partition - Try to restore the disk image to a different partition.
  • Restart the computer - Choosing this option will lead to rebooting your machine, so please close all applications first before selecting it. As an alternative you might restart your computer in a normal way. After you restart, start Active @ Disk Image and repeat the attempt to clone the partition.
  • Force volume dismount - If you don't know what is preventing the partition from being locked, use force volume dismount. Keep in mind that all open file handles on the target partition will become invalid and the application that opened them might crash.

Note

Although force volume dismount will work in most cases, it will not allow exclusive access when you are writing to a system partition or to a partition that is involved with system memory pagefiling. If you are dealing with either of these two cases, you may run Active@ Disk Image from a bootable CD or start your computer in such a way that the target partition is not part of the operating system. You can do this on a computer with multiple systems installed, by booting a different system or you can remove the target disk and install it into another computer where it will not be a system disk.
