OWC Mercury Elite Pro Dual mini Chapter 4 -Troubleshooting & Tips
4 TROUBLESHOOTING, TIPS & FAQ
4.1 Troubleshooting
Some of the most simple problems can be traced to power, or
connectivity issues. Verify that your cables (both ends!) are properly
plugged into the computer and storage solution. If one connection type
does not work, switch to another interface and try the solution again. If
these suggestions do not work, try the OWC Mercury Elite Pro Dual mini on
a dierent computer, if available to you.
• Drive activity light changes color to RED:
One of the internal hard drives is not responding properly and the LED
status lights are alerting you to this issue. You could have a failed hard drive;
note that the OWC Mercury Elite Pro Dual mini’s LED lights correspond to
the drive mechanism, left and right. You should be able to tell which drive
mechanism is at fault and remove it from the enclosure for further testing
or replacement.
If your OWC Mercury Elite Pro Dual mini is congured as a RAID-1 Mirror,
you can install another identical capacity hard drive in place of the failed
mechanism and the RAID will automatically rebuild, even if not connected
to a computer. It’s suggested if you do have a failed drive and are using the
OWC Mercury Elite Pro Dual mini in the RAID-1 conguration, that you let
the unit sit overnight to completely nish the rebuilding process but you
can continue to use the OWC Mercury Elite Pro Dual mini during the rebuild
process as well.
• Drive activity lights both ash BLUE (RAID-1 Mirror only):
One of the internal hard drives has been replaced, and the OWC Mercury
Elite Pro Dual mini is rebuilding the RAID.
• Drive does not power up over eSATA connection:
The OWC Mercury Elite Pro Dual mini eSATA interface requires the use of
a secondary uplink or auxiliary power adapter to use the eSATA interface.
eSATA does not supply bus power. Please see section 4.2 for more
information about those options.
• Drive connected via eSATA, but mounts as FireWire 800 device:
You are likely using a FireWire 800 cable to bus power the OWC Mercury
Elite Pro Dual mini. Switch to using the FireWire 800 to 12V adapter cable or
reboot with the drive turned on and both cables plugged in.
