Basic Storage Versus Dynamic Storage

Was trying to setup mirrored volume (RAID-1) for redundancy and data availability on my PCs. I have done it with the server (Windows Server 2003) in the office. It make use of dynamic disk volume.

 Deng ! Hit the wall, Windows XP doesn't support this ! The dynamic disk feature in Windows XP Pro only allows Extending Volume, meaning you can increase the disk space WITHOUT re-partitioning it and of course no need to restart of PC. I can easily convert a basic disk to dynamic disk, but i can't convert a dynamic disk back to basic without deleting all the dynamic volume... damn... there i go again, transferring all the files.

Basic Disk Storage

Basic storage uses normal partition tables supported by MS-DOS, Microsoft Windows 95, Microsoft Windows 98, Microsoft Windows Millennium Edition (Me), Microsoft Windows NT, Microsoft Windows 2000, and Windows XP. A disk initialized for basic storage is called a basic disk. A basic disk contains basic volumes, such as primary partitions, extended partitions, and logical drives.

Additionally, basic volumes include multidisk volumes that are created by using Windows NT 4.0 or earlier, such as volume sets, stripe sets, mirror sets, and stripe sets with parity. Windows XP does not support these multidisk basic volumes. Any volume sets, stripe sets, mirror sets, or stripe sets with parity must be backed up and deleted or converted to dynamic disks before you install Windows XP Professional.

Dynamic Disk Storage

Dynamic storage is supported in Windows 2000 and Windows XP Professional. A disk initialized for dynamic storage is called a dynamic disk. A dynamic disk contains dynamic volumes, such as simple volumes, spanned volumes, striped volumes, mirrored volumes, and RAID-5 volumes.

NOTE: Dynamic disks are not supported on portable computers or on Windows XP Home Edition-based computers.

You cannot create mirrored volumes or RAID-5 volumes on Windows XP Home Edition, Windows XP Professional, or Windows XP 64-Bit Edition-based computers. However, you can use a Windows XP Professional-based computer to create a mirrored or RAID-5 volume on remote computers that are running Windows 2000 Server, Windows 2000 Advanced Server, or Windows 2000 Datacenter Server. You must have administrative privileges on the remote computer to do this.

Storage types are separate from the file system type. A basic or dynamic disk can contain any combination of FAT16, FAT32, or NTFS partitions or volumes.

A disk system can contain any combination of storage types. However, all volumes on the same disk must use the same storage type.

Dynamic Storage Terms:

A volume is a storage unit made from free space on one or more disks. It can be formatted with a file system and assigned a drive letter. Volumes on dynamic disks can have any of the following layouts: simple, spanned, mirrored, striped, or RAID-5.
A simple volume uses free space from a single disk. It can be a single region on a disk or consist of multiple, concatenated regions. A simple volume can be extended within the same disk or onto additional disks. If a simple volume is extended across multiple disks, it becomes a spanned volume.
A spanned volume is created from free disk space that is linked together from multiple disks. You can extend a spanned volume onto a maximum of 32 disks. A spanned volume cannot be mirrored and is not fault-tolerant.
A striped volume is a volume whose data is interleaved across two or more physical disks. The data on this type of volume is allocated alternately and evenly to each of the physical disks. A striped volume cannot be mirrored or extended and is not fault-tolerant. Striping is also known as RAID-0.
A mirrored volume is a fault-tolerant volume whose data is duplicated on two physical disks. All of the data on one volume is copied to another disk to provide data redundancy. If one of the disks fails, the data can still be accessed from the remaining disk. A mirrored volume cannot be extended. Mirroring is also known as RAID-1.
A RAID-5 volume is a fault-tolerant volume whose data is striped across an array of three or more disks. Parity (a calculated value that can be used to reconstruct data after a failure) is also striped across the disk array. If a physical disk fails, the portion of the RAID-5 volume that was on that failed disk can be re-created from the remaining data and the parity. A RAID-5 volume cannot be mirrored or extended.
The system volume contains the hardware-specific files that are needed to load Windows (for example, Ntldr, Boot.ini, and The system volume can be, but does not have to be, the same as the boot volume.
The boot volume contains the Windows operating system files that are located in the %Systemroot% and %Systemroot%\System32 folders. The boot volume can be, but does not have to be, the same as the system volume.

Wild Hibiscus

found this nice wild hibiscus around my house.

It won't stay for long. It will most probably dried out by the 3rd day

last but not least, happy holiday


Quite some people as me does the .ws domain exist ? This is mainly because so happen the whole domain is my name :-) it's not a normal .com or .net, but .ws

well ya, it exist and below are some info on it

From Wikipedia, the free encyclopedia

It has been marketed — and achieved a degree of popularity — as an alternative to the more "crowded" generic top-level domains, where the selection of unregistered domain names is much more limited. In this context, .ws is suggested to stand for "web site", "world site" or "web service"; the original intent was to abbreviate "Western Samoa", the nation's official name when two-letter country codes were standardized in the 1970s. There are no geographic restrictions on registration of .ws domains.

2nd level domains: 3 TLDs for domain registration to the general public: .WS, .COM.WS and .NET.WS. WS also offers 3 restricted TLDs: .ORG.WS, .GOV.WS and .EDU.WS.

One limitation of .ws is that existing domains registered in this TLD are not portable; they cannot be moved from one registrar to another.[1] The use of wildcard DNS records to serve advertising on all unregistered and newly-registered .ws domains is also an issue.
