Hot Swap
Hot Swap refers to the ability to add or remove a device from the host computer
without first powering off the device. After adding or removing the device, the
operating system automatically recognizes the change. Due to the chipset, hot swap
support varies by RAID System model.
Note:
Because Span/Stripe mode combines two drives into a single logical unit, hot
swapping hard drives will halt RAID function. Hot swapping is not recommended in
Span or Stripe modes.
eSATA/USB 2.0 Model
The eSATA/USB 2.0 model supports HDD hot swap in JBOD and Mirror modes. Hot
swapping the HDD when the other HDD is transferring data when connected via
USB2.0 in JBOD mode is not recommended. When one HDD is hot swapped in
JBOD mode, the system will reset interrupting data transfer and causing data loss.
USB 2.0 Model
The USB 2.0 model does not support HDD hot swap in JBOD or Mirror modes.
Ensure that the RAID System is powered off before replacing HDDs.
USB 2.0/FireWire 800 Model
The USB 2.0/FireWire 800 model supports device HDD hot swap in JBOD and Mirror
modes. Hot swapping the HDD when the other HDD is transferring data is not
recommended in JBOD and Mirror modes. When one of the HDDs is hot swapped,
the system will reset interrupting data transfer and causing data loss.
