  • A:

    The reasons for an external hard drive producing unusual noises could be aging, abnormalities in the circuit board, or read/write tracks. It could also be caused by the read/write head module inside the hard drive being displaced due to impact.

     

    If the hard drive emits metallic clicking sounds and experiences slow read speeds or computer crashes, it is recommended to immediately back up your data, unplug the hard drive's power cable, and send it for repair.

    ‎
  • A: The external hard drive requires a start-up current of over 600 milliamps, however USB 2.0 can only provide a maximum of 500 milliamps. As a result, it is recommended that you use a Y-cable we using with a USB 2.0 host devices.‎
  • A:

    Backup ToGo does not support an encryption function. Use of built-in Windows encryption software BitLocker is recommended (click here to enable BitLocker encryption mechanism on Windows 10 devices).

    ‎
  • A: There are two general possibilities :
    ● Lack of power: The hard disk should be attached to the USB power cable connector into the USB slot on the back of the computer. Make sure your computer supplies enough power for the hard disk to run. Do not use a USB Hub, extension cord, or other USB devices together, because doing so may cause power undersupply, resulting in the external drive being unable to be read.
    ● Volume has not been added: In Windows XP/Vista/7 operating systems, go to Disk Management to confirm that the hard disk is installed.‎
