Troubleshooting︱
If a problem occurs with your StoreJet 25, please first check the information listed below before
taking your StoreJet 25 in for repair. If you are unable to remedy a problem after trying the
following suggestions, please consult your dealer, service center, or local Transcend branch office.
We also have FAQ and Support services on our website at www.transcend.com.tw.
My operating system cannot detect the StoreJet 25
Check the following:
1. Is your StoreJet 25 properly connected to the USB port? If not, unplug it and plug it in again. If
it is properly connected, try using another available USB port.
2. Are you using the USB cable that came in the StoreJet 25 package? If not, try using the
Transcend USB cable to connect the StoreJet to your computer.
3. A single USB port may not provide enough power for the StoreJet 25 to function. Please
connect both the USB 3.0 Cable and the USB Power Cable to your computer. If your StoreJet
25 makes strange noises upon plugging it in, or if you experience problems while reading /
writing data, please connect the USB Power Cable.This will provide the additional power
necessary to run the drive.
The USB Power Cable can provide additional
power for the StoreJet 25 if necessary
4. Is your StoreJet 25 connected to a Mac
®
Keyboard? If so, unplug it and plug it into an available
USB port on your Mac
®
desktop computer.
5. Is the USB port enabled? If not, refer to the user’s manual of your computer (or motherboard)
to enable it.
6. Avoid connecting the StoreJet 25 through a USB hub.
The StoreJet 25 does not power on
Check the following:
1. A single USB port may not provide enough power for the StoreJet 25 to function. Please
connect both the USB 3.0 Cable and the USB Power Cable to your computer.
2. Ensure that the StoreJet 25 is properly connected to the USB port(s) on your computer.
3. Ensure that the USB port is working properly. If not, try using an alternate USB port.
I installed an OS onto the StoreJet 25. Why can’t I boot from it?
Current USB 3.0 host devices do not support operating system boot up.
I cannot copy large files to the StoreJet 25

18
1. Is there enough available disk space?
2. Is the file larger than 4GB? If so, please see below:
The StoreJet 25 default file system is FAT32, which allows it to be recognized on most types of
computers, game consoles and media playback devices. However, the FAT32 file system does
not support large files that exceed 4GB in size. If you plan to store large files that are larger than
4GB, you will need to convert the drive to a different file system such as NTFS. Please see the
“Formatting the Hard Drive” section of this manual for instructions on how to re-format the
StoreJet 25.
I’m having problems with the StoreJet 25 on my Mac
®
If you previously formatted your StoreJet in Windows
®
, it is most likely formatted with the Windows
NTFS file system, which may not be 100% compatible with Mac
®
OS. To store and backup data on
your Mac
®
please follow the instructions on formatting to convert the drive to Mac OS file system.
If you plan to regularly use the drive with both Windows and Mac computers, we recommend
formatting the drive to the FAT32 file system (the StoreJet comes pre-formatted with FAT32 from
the factory). Keep in mind that formatting the drive will erase all existing data on the drive.
Note: To keep existing data, you will need to use a Windows or Mac computer that can
detect the StoreJet drive to make a backup copy of all essential files.
I cannot detect the StoreJet 25 in Linux
®
If you previously formatted the StoreJet 25 a Windows or Mac computer, it is most likely formatted
with a file system that is not compatible with Linux. To solve this problem, please follow the
instructions on formatting the StoreJet 25 in Linux. However, please be aware that formatting the
drive will erase all existing data on the drive.
Note: To keep existing data, you will need to use a Windows or Mac computer that can
detect the StoreJet drive to make a backup copy of all essential files.
