Case study - foreign dynamic disk

I have Windows XP Pro with 80GB seagte hard drive. I have installed a new second hard drive, which had data from my old second hard drive written to it on another PC. The hard drive is seen in the BIOS and in Hardware Devices, where is said to be working properly, but it is not in explorer. I looked in My Computer/Manage/Disk Management and the disk is there but is shown as Dynamic Foreign. I right click on it and get two usable options: Convert to Basic Disk and Import Foreign Disks. Which option is better?

Why disk shows as dynamic foreign?

There are two reasons why dynamic disk shows up as foreign status as following:

Reason 1: The dynamic disk comes from another computer installing Windows 2000, Windows XP 64-bit Edition (Itanium), Windows XP Professional or Windows Server 2003 family Operating System.

Reason 2: Computers are configured to dual-boot with Windows XP Home Edition and another Operating system (such as Windows 2000 Professional or Windows XP Professional) that uses dynamic disks, which are not supported on Windows XP Home Edition or on portable computers.

How to repair foreign dynamic disk?

As the case study mentioned, there are two ways to repair the problem with built-in Disk Management.

Solution 1: Import the foreign disk

To access data on the disk, you must add the disk to your computer's system configuration. In Disk Management, right click the foreign disk and select "Import Foreign Disks". After that, any existing volumes on the foreign disk become visible and accessible.

Solution 2: Convert foreign dynamic disk to basic disk

Because Windows XP Home Edition and portable computer cannot support dynamic disk, you must convert dynamic disk to basic which will destroy all data on the disk. In Disk Management, right click the foreign disk and select "Convert to Basic Disk". After that, the disk becomes empty basic disk.
