Sayfayı YazdırQ: My computer can see the RTX Secure volume, but it shows
up twice. Which one is real?
A: If you are seeing your RTX volume mounted twice, chances are
the unit is connected to the computer using both the eSATA and
FireWire connections. When this is the case, the OS may attempt
to mount the RTX twice resulting in two volumes appearing.
Simply unmount the volumes, turn off the RTX, and unplug one of
the connections to resolve the problem.
Q: Why won't the computer let me eject or unmount my drive?
A: If the drive is connected via eSATA, it cannot be ejected in Win-
dows the way FireWire drives can. However, the third party free-
ware utility called Hotswap can provide a similar function. This is
available here: http://mt-naka.com/hotswap/index_enu.htm
If you are not connected via eSATA, this is not a defect or issue
caused by the RTX Secure and there may instead be a software
application running in the background with an active connection
to the drive. Sometimes, you may see a message such as "The
disk is in use and could not be ejected. Try quitting applications
and try again." Try invoking the Force Quit feature in OS X to see
what software may be running. For Windows, the equivalent
command is CTRL+SHIFT+ESC.
Q: What is an acceptable temperature for my hard drives and
the RTX Secure?
A: Your hard drives can run between 30-40° Celsius without any risk
of overheating. The RTX should trigger the fans to operate when
the enclosure reaches 36° Celsius, so ideal temperatures should
also range from 30-40° Celsius.
Q: Why does my eSATA device appear as a Parallel SCSI
device in System Profiler (MacOS)?
A: The "Serial ATA" tab in System Profiler shows devices attached
to the internal SATA bus, but not always devices attached to an
eSATA host card. Sometimes these devices will appear under the
heading "Parallel SCSI" instead. This is entirely normal and does
not indicate a problem with the device or its drivers.
Q: What is the difference between recoverable and persistent
errors?
A: Recoverable Errors (aka Transient Error or Disk Error) represent
minute errors that the RAID system encounters during data
transfers. These errors are common for RAID setups and are not
necessarily indicative of a drive failure. It is normal for any given
disk in a RAID array to occasionally encounter and report these er-
rors, but a string of these errors may indicate the upcoming failure
of that particular disk.
Persistent Errors (aka Hard Error or Disk Failure) represent the
major errors that can affect a drive and cause it to be removed
from the RAID array. This can be caused by electrical removal
(e.g. drive is physically disconnected from the controller, drive
suffers electrical failure, drive loses power, etc.) or by a failure
to respond (e.g. the given disk no longer responds to commands
given by the controller). In either case, the result is a degraded
RAID set and a failed disk.
Q: What should I do on a reboot when the RTX Secure
prompts me to "Re-init" the RAID?
A: If you are simply rebooting the unit and want to return to the "Ac-
tive Menu" then let the RTX Secure complete the start up cycle
and it will arrive at the "Active Menu" momentarily. Do not press
any buttons on the front display.
If you bought an RTX Secure without drives and you want to set
up a RAID 5 with four disks (default RAID type) then simply insert
your drives and select the "Re-init" (left) button on the front dis-
play. RTX will verify the RAID 5 with four disks and you can select
the "-Init" (left) button on the front display to set up that RAID. If
you desire a different RAID type or disk number refer to section 7
in the User Manual for further instructions.
