or below 5℃.
• Do not drop your StoreJet 25.

• If your Windows computer will not boot while StoreJet 25 is connected, please
disconnect the StoreJet 25 to your computer first and connect the StoreJet 25 after
starting Windows. Otherwise, refer to your computer's manual and change the BIOS
settings to instruct the computer to boot from a different device.
Backing up Data
• Transcend does NOT take any responsibility for data loss, or damage during
operation. If you decide to store data on your StoreJet 25 we strongly advise that you
regularly backup the data to a computer, or other storage medium.
• To ensure Super-Speed USB 3.0 data transfer rates when using your StoreJet 25,
please make sure that your computer has the relevant drivers and hardware to support
USB 3.0. If you are unsure about how to check this, please consult the user’s manual of
your computer, motherboard, or USB 3.0 interface card for USB 3.0 driver information.
Transporting
• Do not pack the StoreJet 25 into luggage without proper padded support. Other items in
your luggage may damage the drive during travel if it does not have proper protection.
• Avoid squeezing or compressing the StoreJet 25.
• Do not place objects on top of your StoreJet 25.
Power
• The SJ25H3 gets its power directly from your computer’s USB port. However, the power
supplied by the USB ports on some older computers does not meet the stable 5V DC
power requirements of the SH25H3. If your StoreJet does not function properly upon
connecting it to your computer, please plug BOTH ENDS of the USB 3.0 Y-cable into
your computer.

5
Both ends of the USB 3.0 Y-cable should be
connected to provide ample power to the
SH25H3
• Use only the USB 3.0 cable that came with the StoreJet 25 to connect it to a computer,
and always ensure that the cable you are using is in good condition. NEVER use a cable
that is frayed or damaged.
• Ensure nothing is resting on the USB cable and that the cable is not located where it can
be tripped over or stepped on.
Reminders
Always follow the procedures in the “Disconnecting from a Computer” section to remove the
StoreJet from your computer.
