Convert to Basic and Dynamic Disks in Windows XP

Windows XP Professional supports two types of disk storage: basic and dynamic. Basic disk storage uses partition-oriented disks. A basic disk contains basic volumes (primary partitions, extended partitions, and logical drives).

Dynamic disk storage uses volume-oriented disks, and includes features that basic disks do not, such as the ability to create volumes that span multiple disks (spanned and striped volumes).

General Notes
Before your change a basic disk to a dynamic disk, note these items:

You must have at least 1 megabyte (MB) of free space on any master boot record (MBR) disk that you want to convert. This space is automatically reserved when the partition or volume is created in Microsoft Windows 2000 or Windows XP Professional. However, it may not be available on partitions or volumes that are created in other operating systems.

When you convert to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk, and then convert the dynamic disk back to a basic disk. If you want to keep you data, you must first back up or move the data to another volume.

After you convert to a dynamic disk, the dynamic volumes cannot be changed back to partitions. You must first delete all dynamic volumes on the disk, and then convert the dynamic disk back to a basic disk. If you want to keep your data, you must first back up or move the data to another volume.

After you convert to a dynamic disk, local access to the dynamic disk is limited to Windows XP Professional and Windows 2000.

If your disk contains multiply installations of Windows XP Professional or Windows 2000, do not convert to a dynamic disk. The conversion operation removes partition entries for all partitions on the disk with the exception of the system and boot volumes for the current operating system.

Dynamic disks are not supported on portable computers or Microsoft Windows XP Home Edition.

Before you change a dynamic disk back to a basic disk, note that all existing volumes must be deleted from the disk before you can convert it back to a basic disk. If you want to keep your data, back up the data, or move your data to another volume.

How to Convert a Basic Disk to a Dynamic Disk.

To convert a basic disk to a dynamic disk:

1) Log on as Administrator or as a member of the Administrators group.

2. Click Start, and the click Control Panel.

3) Click Performance and Maintenance, click Administrative Tools, and the double-click Computer Management.

4) In the left pane, click Disk Management.

5) In the lower-right pane, right-click the basic disk that you want to convert, and the click Convert to Dynamic Disk.

NOTE: You must right-click the gray are that contains the disk title on the left side of the Details pane. For example, right-click Disk 0.

6) Select the check box that is next to the disk that you want to convert (if it is not already selected), and the click OK.

7) Click Details if you want to view the list of volumes in the disk.

8) Click Convert.

9) Click Yes when you are prompted to Convert, and the click OK.

How to Convert a Dynamic Disk to a Basic Disk.

To change a dynamic disk back to a basic disk:

1) Back up all the data on all the volumes on the disk you want to convert to a basic disk.

2) Log on as Administrator or as a member of the Administrators group.

3) Click Start, and the click Control Panel.

4) Click Performance and Maintenance, click Administrative Tools, and the double-click Computer Management.

5) In the left pane, click Disk Management.

6) Right-click a volume on the dynamic disk that you want to change to a basic disk, and then click Delete Volume.

7) Click Yes when you are prompted to delete the volume.

8) Repeat steps 4 and 5 for each volume on the dynamic disk.

9) After you have deleted all the volumes on the dynamic disk, right-click the dynamic disk that you want to change to a basic disk, and then click Convert to Basic Disk.

NOTE: You must right-click the gray area that contains the disk title on the left side of the Details pane. For example, right-click Disk 1.

Good luck!

how tp convert a GPT hard drive to a MBR hard drive? thanks


Boot off your Vista disc and go to the Recovery options. Once inside there access Command Prompt (It is a choice in the Menu) type Diskpart.exe and hit enter. Then type Help you will see many options.

What you want to do is type 'List Disk' select the Disk you wish to convert and so forth. Basically the way to convert from GPT to MBR is in there. You can also clean all data off the disk from inside Diskpart and start over with MBR.
Commands to Convert Disks
convert mbr [noerr]

Use the convert mbr command to set the partitioning style of the current disk to MBR. The disk may be a basic disk or a dynamic disk but the disk must not contain any valid data partitions or volumes.

convert gpt [noerr]

Use the convert gpt command to set the partitioning style of the current disk to GPT. The disk may be a basic or a dynamic disk but it must not contain any valid data partitions or volumes. This command is valid only on Itanium-based computers; it may be unsuccessful on x-86-based computers.

convert dynamic [noerr]

Use the convert dynamic command to change a basic disk into a dynamic disk. The disk may contain valid data partitions.

convert basic [noerr]

Use the convert basic command to change an empty dynamic disk to basic.

seagate freeagent drive


Hi George,

The seagate freeagent should be reconigized by windows. The question is are you adding an additional partition or do you want to create a brand new partion. I'm assuming you want to add.

You can add more space to existing primary partitions and logical drives by extending them into adjacent, contiguous unallocated space on the same disk. To extend a basic volume, it must be formatted with the NTFS ile system. You can extend a logical drive within contiguous free space in the extended partition that contains it. If you extend a logical drive beyond the free space available in the extended partition, the extended partition grows to contain the logical drive as long as the extended partition is followed by contiguous unallocated space.

To extend a basic volume
  1. Open Command Prompt.
  2. Type: diskpart
  3. At the DISKPART prompt, type: list volume
    Make note of the number of the basic volume you want to extend.
  4. At the DISKPART prompt, type: select volume n
    Selects the basic volume, n, you want to extend into contiguous, empty space on the same disk.
  5. At the DISKPART prompt, type: extend [size=n] Extends the selected volume by size=n megabytes (MB).
Value Description list volume Displays a list of basic and dynamic volumes on all disks. select volume Selects the specified volume, where n is the volume number, and shifts the focus to it. If no volume is specified, the select command lists the current volume with focus. You can specify the volume by number, drive letter, or mount point path. On a basic disk, selecting a volume also gives the corresponding partition focus. extend Extends the volume with focus into next contiguous unallocated space. For basic volumes, the unallocated space must be on the same disk as, and must follow (be of higher sector offset than) the partition with focus. A dynamic simple or spanned volume can be extended to any empty space on any dynamic disk. Using this command, you can extend an existing volume into newly created space. If the partition was previously formatted with the NTFS file system, the file system is automatically extended to occupy the larger partition. No data loss occurs. If the partition was previously formatted with any file system format other than NTFS, the command fails with no change to the partition.
You cannot extend the current system or boot partitions.
size=n The amount of space, in megabytes (MB), to add to the current partition. If you do not specify a size, the disk is extended to take up all of the next contiguous unallocated space.
Notes
  • To open a command prompt, click Start, point to All Programs, point to Accessories, and then click Command Prompt.
  • You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.
  • To extend a basic volume, it must be formatted with the NTFS file system.
  • You can only extend a basic volume onto the same disk.
  • You can only extend a basic volume if it is followed by contiguous unallocated space.


Hope this helps!

Thanks
Mark
