administrators to keep accurate record of when the event actually occurs.
4.9.2 Utility Configuration (only available 8990 controller)
Clone
Is used to set the bad sector threshold of a hard drive.
When the bad sector count equals to this value then the disk
will be cloned.
Swap

When the bad sector count equals to this value then the disk
will be replaced with a pre-cloned disk. To function
properly this value must be grater then the value set for
clone.
Unit Per Sector

be recognized under Windows based operating system.
