VMware Workstation 4.5
Windows 2000, Windows XP and Windows Server 2003 support a disk type called a dynamic disk. Dynamic disks use a proprietary Microsoft format for recording partition information. This format is not publicly documented and thus is not supported for use in raw disk configurations under VMware Workstation.
Windows 2000, Windows XP and Windows Server 2003 also support the older type of partition table. Disks that use this type of partition table are called basic disks.
You can use the disk management tool to check the type of disk used on your Windows 2000, Windows XP or Windows Server 2003 host and, if it is a dynamic disk, change it to basic.
Caution: If you change a dynamic disk to a basic disk, you lose all data on the disk.
Use this procedure to convert a dynamic disk to a basic disk.
