Windows, NetWare and other advanced operating systems sup-
port volume expansion, which enables you to incorporate the
additional free space within the volume into the operating sys-
tem partition. The operating system partition is extended to
incorporate the free space so it can be used by the operating
system without creating a new operating system partition.
You can use the Diskpart.exe command line utility, included with
Windows Server 2003 or the Windows 2000 Resource Kit, to
extend an existing partition into free space in the dynamic disk.
Third-party software vendors have created utilities that can be
used to repartition disks without data loss. Most of these utilities
work ofine. Partition Magic is one such utility.

• Hot-Swap Disk Drive Support
The SATA controller chip includes a protection circuit that sup-
ports the replacement of SATA hard disk drives without having
to shut down or reboot the system. A removable hard drive tray
can deliver “hot swappable” fault-tolerant RAID solutions at prices
much less than the cost of conventional SCSI hard disk RAID
controllers. This feature provides advanced fault tolerant RAID
protection and “online” drive replacement.
• Auto Rebuilding
The failed disk drive must be replaced with a new disk drive so
that the data on the failed drive can be automatically rebuilt and
so that fault tolerance can be maintained.
The SATA RAID controllers will automatically restart the system
and the rebuild process if the system is shut down or powered off
abnormally during a reconstruction procedure condition.
When a disk is hot swapped, although the system is functionally
operational, the system may no longer be fault tolerant. Fault
tolerance will be lost until the removed drive is replaced and the
rebuild operation is completed.
During the automatic rebuild process, system activity will contin-
