I have 2 western digital 1 terra byte hard drives and they both work fine when I connect them independently to my computer but now when I wanted to transfer data from one onto another I plugged them into my USB ports but only one will show up in my computer.
I tried reconnecting them to different ports than those I used earlier but still the problem persists. It won’t be an issue of power since I am connecting both of them to my laptop. Since I have tried that also with my laptop connected to the charger, I would be glad for any help?
My computer cant detect 2 external hard disks
I also have the same problem with my external drive. My PC does not detect the device with it, when it is plugged in any of the front USB ports but if you plug it in the back of the CPU it still won’t detect it, but after restarting the system that’s the time it will detect the drive. This is due to insufficient power given by the CPU to the external drive.
Modern external drives often consume a lot of power from your CPU. I often remove some devices from my CPU just to accommodate the external drive. The only way to remedy this is to upgrade the PSU (Power Supply Unit) of your PC. The commonly install PSU in the average CPU has a voltage of 500 watts. I recommend upgrading to about 600 to 700 watts. From the looks of it, you might need a whole lot of power to support your 2 external drives.
I hope this will help you.
