Backup Plus Portable (USM) Troubleshooter
Check the Cabling
Please check the cabling.
Backup Plus Portable drives are powered by the port to which they are connected. If you are
using the USB interface, some USB ports do not provide enough power to power up the drive
(the drive will sometimes blink or make a beep sound if it does not have enough power).
1. If you are connecting the drive via a USB port on a PC Express or PCMCIA card, these may not be
able to provide enough power.
o Please try connecting the drive to a USB port on the computer itself, for troubleshooting
purposes.
o Please also check for updates for the card's drivers. If an update exists, apply it and then
reconnect the drive to test detection.
2. Be sure to use a USB port on the back of the computer (if you have a desktop computer).
3. Please do not connect the drive to a USB port on your keyboard or computer monitor.
4. Please try a different USB cable that you know functions correctly with another device,
preferably another external hard drive.
5. Please remove any extraneous peripherals such as USB hubs, extension cables, etc. so that the
external drive is connected directly to the computer.
6. These drives also include interchangeable interface modules, which are listed in Document ID:
214431.
Please ensure that the following are well-connected and not loose:
a. Cable module to drive
b. Cable to cable module
c. The other end of the cable to the port on the computer
If the drive is beeping, it may be that your computer does not supply enough power. Please
connect the drive via a powered USB hub.
Remove Potential Conflicts
Please continue troubleshooting:
7. The USB 2.0 modules’, as well as some USB 3.0 modules’, cable can separate from the
module for greater flexibility.
Try to connect the drive using a different standard USB mini-B cable or a different
GoFlex, Backup Plus, GoFlex Satellite, or Wireless Plus module, if you have one.
However, be careful when using longer cables as they may not transfer enough power to
allow the drive to function.
