E.1 Introduction
The ALi M5283 SATA RAID chipset can control parallel ATA (PATA) and serial ATA
(SATA) disks. The ALi controller supports PATA UDMA transfer mode up to mode 6 and
SATA 1 disk drives. The ALi M5283 also has a cost-effective RAID functionality that can
increase the data read/write speed and provide protection to data by distributing mirrored
duplicates of data onto two disk drives (RAID 1).
CAUTION!
A configured RAID volume (which may consist of multiple hard drives)
appears to an operating system as a contingent storage space. The operating
system will not be able to distinguish the physical disk drives contained in a
RAID configuration.
E.1.1 Precautions
One key benefit a RAID configuration brings is that a single hard drive can fail within a
RAID array without damaging data. With RAID1 array, a failed drive can be replaced and
the RAID configuration restored.
WARNING!
Irrecoverable data loss occurs if a working drive is removed when trying to
remove a failed drive. It is strongly recommended to mark the physical
connections of all SATA disk drives. Drive locations can be identified by
attaching stickers to the drive bays. If a drive member of a RAID array should
fail, the failed drive can then be correctly identified.
CAUTION!
Do not accidentally disconnect the SATA drive cables. Carefully route the
