Battery Handling Guidelines and Safety Precautions
This product includes an internal lithium-ion battery. Please follow the safety precautions below.
If the battery pack is leaking fluid, do not come into contact with the fluid.
Battery fluid can cause burns. Also, if the fluid gets on your skin or clothes, immediately rinse the fluid off with
water, and seek medical attention. If the uid gets in your eyes, it can lead to permanent loss of eyesight, and so
immediately ush your eyes thoroughly with clean water and seek medical treatment.
Never get the battery pack wet, or put it inside water or other liquids.
This can cause overheating, rupture, ignition, or a failure of the battery pack. If the battery pack gets wet,
immediately stop usage, and contact the Bualo Technology Support Center or your local dealer.
Never disassemble or modify the battery pack.
This could cause the uid in the battery pack to splash out, which can lead to permanent loss of eyesight if it gets in
your eyes, or can lead to overheating, rupture, or ignition of the battery.

Computer Connection (USB Connection) Guidelines
To avoid damage to data, follow these precautions:
Never congure this unit as a destination for virtual memory.
Never do any of the following while the power LED is blinking:
- unplug the USB data cable
- turn o your computer
- put your computer into standby, hibernate, or sleep mode
The MiniStation Air supports hot-plugging.
You can plug or unplug the USB data cable even if it and your PC are on. However, never unplug the USB data cable
while the power LED is blinking, or your data may be lost or damaged.
To charge the MiniStation Air, connect the USB power cable to a port on your computer.
The USB data cable may also charge the unit, but at reduced power because its power is also being used to run the
hard drive.
If the MiniStation Air does not operate normally, the problem might be that your computer doesn’t provide enough
power through the data cable.
Try attaching the USB power cable to an AC adapter with a USB port.
Booting Windows from this drive is not supported.
The MiniStation Air supports USB 3.0.
If it is connected to a USB 2.0 or USB 1.1 port, Windows may display a message that a high speed USB device is
connected to a non high-speed USB device. To continue, click “X”.
You may hear some noise while the MiniStation Air is working, especially when it is booting or being accessed. This
is normal.

Notes
The following restrictions apply to this product. Please check these points before use.
While the MiniStation Air is connected to a computer with the USB data cable, Wi-Fi is disabled.
Unplug the USB data cable before connecting wirelessly.
To charge this unit, it is recommended that you use the supplied USB power cable together with an AC adapter with
USB port provided with a smartphone or other device to connect this unit to an outlet.
If the USB power cable is used to connect to a computer, the supplied power varies depending on the computer. This
means that the charging time will also vary depending on your com-puter. Although the battery LED turns on when
the unit is connected to a computer by the USB data cable, the power is also being used to run the unit, and so the
charging time will be longer than when the unit is idle (in certain cases, the unit may hardly be charged at all).
If this unit is charged while connected wirelessly, the battery LED may turn off and charging may not be performed
in certain cases.
If this unit is charged while connected wirelessly, the internal temperature of the unit can be-come hot. If this
happens, to prevent unit damage due to overheating, the battery LED turns o, and charging is stopped. Once the
internal temperature of the unit drops, charging is restarted automatically.
The battery in this unit cannot be removed.
After the power is turned on, it takes about 1 minute for the unit to boot. During startup, the power can’t be turned
off.
After the unit is booted normally, hold down the power button for 3 seconds to turn o the power.
Do not shake or drop the MiniStation Air during boot. This could damage the hard drive.
Do not lean any object against MiniStation Air. It may cause the unit to malfunction.
To use files that are 4 GB or larger, reformat with NTFS.
To use the MiniStation Air with Mac OS, leave it in FAT32. The MiniStation Air does not support HFS+.
A maximum of three devices can be connected wirelessly at the same time.
The MiniStation Air selects wireless channels automatically. There is no provision for locking communication to a
single fixed channel.
When the MiniStation Air is connected to the Internet through a wireless router, the wireless throughput to and
from your portable device drops to half.
With this conguration, only a single connected wireless device is recommended.

9

3. Formatting
What is Formatting?
Formatting is an operation that enables a hard drive to be used on your computer.
This unit is formatted with FAT32 by default, and so it can be used without any additional formatting procedure.
However, due to the restrictions of the FAT32 format, this unit cannot save les that are 4 GB or larger in size.
For Windows users
Reformatting with NTFS is recommended for most Windows users. This will let you save les that are 4 GB or larger.
However, Macs will not be able to write to the dive if it is formatted with NTFS.
For Mac users
Keeping the default FAT32 format partition is recommended for Mac users. If the MiniStation Air is reformatted with
HFS+, les on it will no longer be accessible from your iPhone, iPad, iPod touch, Android phones, or other portable
device. If you have already reformatted the MiniStation Air with a different partition, use the procedure in this
manual to reformat it with FAT32.
Formatting Notes
Never unplug, reset, or turn off the computer during the formatting process. This could result in damage to the
drive or other problems. Proper operation cannot be guaranteed if the format process is interrupted.
Formatting will erase all data on the hard drive. Before formatting, back up any data.
The user is responsible for any data lost due to formatting of the hard drive.
Don’t format the wrong drive! Check the drive letter and partition name carefully. If you format the wrong drive, all
data on it will be lost.
Formatting with NTFS (Windows)
If you use a Windows computer primarily, you may reformat the MiniStation Air with NTFS. This will allow les larger
