LED Behavior

This table describes the behavior of the LEDs on the front of the ioSafe Duo. Note that a “RAID array” is how the two hard drives inside the ioSafe Duo are linked together. One of the ways they can be linked together is as a RAID 1, which automatically ensures that an exact copy of your data is always available in case one of the hard drives in the ioSafe Duo dies. Other RAID modes are available. To use them, see Section 2.3.

LED Name	Color	State	Description
Disk Activity LEDs #1-2	Green	Solid	The corresponding drive bay is powered on.
	Green	Slow Blinking	The corresponding drive is being accessed.
	Amber	Solid	Both LEDs are solid amber when the internal temperature of the ioSafe Duo is over 131° F/55° C. Ensure the unit is being stored in a properly ventilated area.
	Amber	Slow Blinking	Indicates that the corresponding drive is being accessed while the internal temperature of the ioSafe Duo is over 131° F/55° C. Ensure the unit is being stored in a properly ventilated area.
	Red	Slow Blinking	Indicates a drive failure or disconnection of the corresponding drive.
	Red	Fast Flickering	The RAID 1 array is being rebuilt. The disk with the red LED is the disk that is being overwritten.
Power LED	Blue	Off	The unit is powered off.
		Solid	The unit is powered on.
		Blinking	A RAID array is being created.
	Red	Solid	Indicates a fan failure. Please contact Technical Support to obtain a replacement fan (see Section 7).
	Red	Blinking	A RAID array is being created at the same time a fan has failed. Please contact Technical Support to obtain a replacement fan (see Section 7).

Warnings and Notices

Please read the following before using the product.General

If a hard drive inside the ioSafe Duo ever fails, do not replace it without consulting Section 5.2 in this manual first. We’ve made the drive replacement procedure very easy to follow, but if you don’t follow it you might accidentally erase your data!
The circuit boards within the product are susceptible to static electricity. Proper grounding is strongly recommended to prevent electrical damage to the product or other connected devices, including the computer host. Avoid all dramatic movement, tapping on the unit, and vibration.

Avoid placing the drive carrier close to magnetic devices or high voltage devices.
Before starting any type of hardware installation, please ensure that all power switches have been turned off and all power cords have been disconnected to prevent personal injury and damage to the hardware.

To avoid overheating, the ioSafe Duo should be operated in a well-ventilated area.

RAID

Use only drives that are in perfect condition. Avoid using drives that have ever developed bad sectors during previous use. This could lead to possible device failure or loss of data.
The ioSafe Duo supports SATA drives of various specifications and different capacities. However, we recommend using drives of the same brand and type for optimal performance that have been qualified by ioSafe. To view a list of qualified drives, please visit iosafe.com.
If drives of different capacities are used in a RAID 1, the capacity of the smallest drive will determine how much of each drive is used. The additional capacity on the larger drive will not be used by the RAID.
Always back up data before switching RAID types. Switching RAID types will destroy current data. You must reformat your drives afterwards.

About USB

Actual connection performance depends on many factors including: CPU, file system overhead, number of attached devices and more. Given these and other factors, in day-to-day use you can expect maximum, sustained transfer rates to be less than the theoretical rates maximum rates possible with the connection.
USB 3.2 is backwards compatible with USB 2.0, USB 3.0, and USB 3.1 host computers.
The cables supplied with your system have been optimized for performance. Longer cables or third-party cables may not work or only work intermittently.

Hardware Setup

Drive Installation

If you purchased an ioSafe Duo with pre-installed drives, skip this section and continue on to Section 2.2.

Tools and Parts for Drive Installation

Phillips screwdriver
Hex tool (included)
At least one 3.5-inch or 2.5-inch SATA hard drive or solid state drive (SSD). Please visit iosafe.com for a list of qualified drive models.

Using drives with previously existing data on them in a new RAID or SPAN array will cause the previously existing data to be erased. Please back up your data before beginning this operation. However, if you are using the ioSafe Duo in JBOD mode, the previously existing data will not be erased. See Section 2.3 for an introduction to the RAID and non-RAID modes that the ioSafe Duo supports.

SATA Drive Installation or Removal

a. Use the included hex tool to remove the screws on the top and bottom of the front cover. Then remove the front cover.

b. Remove the waterproof drive cover with the 3mm hex tool.

c. Remove the drive trays with the hex tool.

d. If you are removing a previously installed hard drive(s), remove the drive(s) from the drive tray by removing the four (4) drive screws holding it into the tray with a Phillips screwdriver.

Otherwise, skip this step.

e. Install a compatible drive into each drive tray using the supplied four (4) drive screws and a Phillips screwdriver. Please visit iosafe.com for a list of qualified drive models.

Since you’ll likely be using this as part of a RAID array, ioSafe recommends that both installed drives should have the same capacity.

f. Insert each loaded drive tray into an empty drive bay, ensuring that each one is pushed in all the way. Then tighten the screws using the hex tool.

g. Replace the waterproof drive cover and securely tighten it using the hex tool.

Avoid using tools other than the supplied hex tool to secure the waterproof drive cover as you could under-tighten or break the screw. The hex tool has been designed to flex slightly when the screw is sufficiently tight and the waterproof gasket is properly compressed.

h. Install the front cover to finish installation and protect the drives from fire.

i. You may optionally use the round magnet provided to attach and store the hex tool on the back of the unit.

Connecting the ioSafe Duo

a. Connect the ioSafe Duo to your computer using one of the provided USB cables.

USB Type-C Cable

For the fastest performance, connect the Duo to a USB 3.2 Gen 2 Type-C port on your computer.

USB Type-C to A Cable

The Duo also runs on USB 3.x and 2.0 Type-A ports.

The cables that come in the box have been optimized for performance. Longer cables or third party cables may not work or only work intermittently

b. Connect the Duo to power using the provided power cord.

If you purchased the ioSafe Duo without pre-installed drives, or if you plan to use a different RAID mode other than RAID 1, do not turn on the power yet. Continue to Section 2.3 instead.

c. Press the power button on the front to turn on the unit.

RAID Configuration

If you purchased the ioSafe Duo with pre-installed drives and you intend to use the default RAID 1 mode, skip this section.

Introduction to RAID

A RAID (Redundant Array of Independent Disks) is an array of multiple data drives that are combined in a way that provides faster performance or data safety. The ioSafe Duo is capable of several RAID and RAID-like modes. Choose your preferred mode based on factors such as disk capacity, desired data safety, and desired performance.

ioSafe recommends that you use this product as a RAID 1 device. RAID 1 automatically maintains an exact copy of all data stored on the Duo and protects you against the loss of a single drive. If you purchased an ioSafe Duo with pre-installed drives, no additional steps are necessary to do use it in this mode. The Duo works as a RAID 1 device right out of the box.

Supported RAID Modes

Mode	Description	Required No. of Drives
RAID 0	All drives are combined into one single volume and benefit from increased read and write speeds at the cost of a higher risk of failure. If one drive fails, the data on all drives is destroyed.	2
RAID 1	Known as mirroring. All data is replicated on two separate disks, so only half of the combined disk capacity is available for data storage.	2

Supported RAID-Like Modes

Mode	Description	Required No. of Drives
JBOD	All drives are treated as individual volumes and will appear as sepa- rate volumes in your operating system.	1
SPAN	All drives are combined into one single volume at the cost of a higher risk of failure. It does not benefit from the same speed advantages that RAID 0 does. If one drive fails, the data on all drives is destroyed.	2

Selecting the RAID Mode

a. Power off the ioSafe Duo.
b. Peel away the RAID Jumper Pin Cover sticker located on the rear of the ioSafe Duo.

c. Insert the included jumper onto the appropriate jumper pins according to your desired RAID mode, which is indicated on the legend above the jumper pins.

d. Press and hold down on the Power button until the Power button begins blinking blue. The Drive Activity LEDs for both disks will also briefly blink red. The blinking indicates that the array is being created.

Failure to hold the power button down will cause the ioSafe Duo to appear on your computer as two separate drives (JBOD Mode) instead of one unified drive, regardless of what RAID jumper setting you use.

e. The Power button will stop blinking and the Disk Activity LEDs will glow a solid green once the array has been created. Verify that the RAID mode is correct (see Section 5.1).

Connect Additional USB Peripherals

The USB ports on the front of the ioSafe Duo allow you to connect additional USB peripherals, including thumb drives and phones. One (1) USB Type-A port and one (1) USB Type-C port have been provided. Any connected devices will connect to your computer like normal.

a. In Windows, go to Control Panel → Devices and Printers. In Windows 10, you can find the Control Panel by typing “Control Panel” into the taskbar search field and selecting the Control Panel app in the results listing.

If your Control Panel is sorted by category, then “Devices and Printers” can be found in the “Hardware and Sound” category.

The Control Panel, sorted by Large Icon view.

b. Right click on the ioSafe Duo device and select Properties. It may be categorized under the “Unspecified” category and named “Device”.

Right-clicking on the ioSafe Duo device in “Devices and Printers”.

c. In the Device Properties window that opens, select the Hardware tab.

d. Select USB Mass Storage Device from the list on the Hardware tab. Then click the Properties button.

e. In the properties window that opens, select the Details tab.

f. Click on the Property drop-down box and select Bus reported device description from the list that appears.

g. In the Value box, you should see text similar to “ASM1352R-XXXXXX,” where the X’s are placeholder names. The X’s correspond to the RAID mode that the device is currently in.

Mode	Corresponding Device Name
RAID 0	ASM1352R-FAST
RAID 1	ASM1352R-SAFE
JBOD	ASM1352R-PM
SPAN	ASM1352R-VOLUME

If the text corresponds to the RAID mode you expected, then you have successfully verified that the RAID array was created successfully. You may skip the remaining steps.

If the text does not correspond to the RAID mode you expected, continue to the next steps to recreate the RAID.

Recreating the RAID will result in the loss of data on your drives. Do not proceed to the next step unless you are sure your data is backed up!

h. If the RAID mode is incorrect or the ioSafe Duo does not appear on your computer, restart the array creation process by powering off the ioSafe Duo. Then, press and hold down on the Power button until the Power button begins blinking blue. The Drive Activity LEDs for both disks will also briefly blink red. The blinking indicates that the array is being created.

i. The Disk Activity LEDs will glow a solid green once the array has been created. Repeat the steps above to verify the RAID.

Replace a Failed Drive in a RAID 1 Array

a. Note which drive has failed, indicated by the Disk Activity LEDs on the front of the ioSafe Duo. The LED corresponding to the failed drive will be red.
b. Shut down the ioSafe Duo.
c. Disconnect the USB cable connecting the ioSafe Duo to your computer.
d. Remove the failed drive. Refer to Section 2.1.2 for detailed instructions.
e. If the good drive is located in the bay labelled “Disk 2”, then move it to the side labelled “Disk 1”.

It is very important to move the remaining good drive to Bay 1. After being powered off, the ioSafe Duo will always rebuild a RAID 1 mirror from the drive located in Bay 1. Failure to place the good drive in Bay 1 will cause your data to be overwritten.

f. Insert the replacement drive into the bay labelled “Disk 2”.

ioSafe recommends that you use a replacement drive with the same capacity as the remaining drive.

g. Reattach the waterproof drive cover and the front cover. Refer to Section 2.1.2 for detailed instructions.

h. Turn on the ioSafe Duo. The Disk Activity LED corresponding to the drive being overwritten will begin flickering red very quickly, indicating that the RAID is rebuilding. This process may take several hours.

Do not attempt to use the ioSafe Duo while the RAID is rebuilding. While the ioSafe Duo can handle data transfers during a rebuild, if something else happens like a loss of power while data is transferring during a RAID rebuild, there is a chance that data loss may occur.

i. Reconnect the USB cable only after the Disk Activity LEDs glow a solid green, indicating that the RAID rebuilding process is complete.

Drive Rotation as Part of a Backup Schedule

ioSafe does not recommend using a backup rotation schedule for the ioSafe Duo, since regular rotation of drives can wear down the waterproof seal and the drives are protected well enough to survive the vast majority of disaster scenarios. Drive rotation should only be carried out between lengthy intervals, if at all.

a. Shut down the ioSafe Duo.

b. Disconnect the USB cable connecting the ioSafe Duo to your computer.

c. Remove the drive from Bay 2. Refer to Section 2.1.2 for detailed instructions.

It is very important to only replace the drive located in Bay 2. After being powered off, the ioSafe Duo will always rebuild a RAID 1 mirror from the drive located in Bay 1. Inserting a replacement drive into Bay 1 will cause your data to be overwritten.

d. Insert the replacement drive into Bay 2.

e. Reattach the waterproof drive cover and the front cover. Refer to Section 2.1.2 for detailed instructions.

f. Turn on the ioSafe Duo. The Disk Activity LED for Bay 2 will begin flickering red very quickly, indicating that the RAID is rebuilding. This process may take several hours.

g. Reconnect the USB cable only after the Disk Activity LEDs glow a solid green, indicating that the RAID rebuilding process is complete.

Replace System Fan

The power LED will turn a solid red if the system fan is not working. Follow the steps below to replace the malfunctioning fan.

a. Shut down your ioSafe Duo. Disconnect all cables connected to your ioSafe Duo to prevent possible damage.

b. Remove the four (4) perimeter screws around the rear fan assembly plate.

c. Pull the assembly from the back panel of your ioSafe to expose the fan connections.

d. Disconnect the fan cables from the connector wires attached to the rest of the ioSafe and then remove the assembly.

e. Install the new fan assembly or replace the existing fans. Connect the fan cables of the new fans to the fan connector wires attached to the main ioSafe unit.

f. Replace and tighten the four (4) screws you removed in Step B.

Troubleshooting

My ioSafe Duo will not show up on my Windows computer and causes it to make repeating disconnection sounds.

If you have properly connected your ioSafe Duo to your Windows computer and turned it on, try turning off the ioSafe Duo and connecting it to a different USB port.

If that is unsuccessful, then you have likely connected the ioSafe Duo to a USB port on your computer that uses what’s known as an ASMedia™ USB host controller, which will need different driver software to work correctly with the ioSafe Duo.

Follow these simple steps to change the driver.

a. Power off the ioSafe Duo.

b. Press Windows Key + X on your keyboard and click on Device Manager from the menu that pops up from the bottom-left corner of the screen.

The Quick Access Menu, pictured, allows you to access the Device Manager.

c. Click on the arrow next to “Universal Serial Bus controllers” from the Device Manager window that pops up to expand the list of USB controllers.

The “Universal Serial Bus controllers” list is located at the bottom of the Device Manager.

d. Right-click on an item in the list that contains both “ASMedia” and “Host Controller” in the label. There may be more than one item in the list. In the submenu that appears, click\ Update driver.

These items will need their driver updated to work properly with the ioSafe Duo. Choose one and follow the remaining steps.

e. Select Browse my computer for driver software on the new window that appears.

Choose “Browse my computer for driver software

f. Choose Let me pick from a list of available drivers on my computer.

Click “Let me pick from a list of available drivers on my computer”.

g. Make sure Show compatible hardware is checked. Then click on USB xHCI Compliant Host Controller. Finally, click the Next button.

This is the USB driver that comes standard in Windows and works with ASMedia USB add-on cards.

h. Repeat Steps C through F for all items in the Device Manager list that say both “ASMedia” and “Host Controller”.

The ioSafe Duo should now appear on your computer. If you experience any issues with this procedure, please contact ioSafe Technical Support (see Section 6.3).
