External Hard Drive not detected by laptop

[robertmanfredsantos]

Hi Guys! I have a 4 TB WD external hard drive that is working fine with my TV and Computer. It's just undetected in my laptop and not showing up in device manager/ disk management. Thanks for the replies in advance.

1. Move it around all of your usb ports and see if one recognizes it
2. Check and install all windows updates
3. Unplug device and reboot machine, then reconnect.

Also, have you changed anything in the bios recently?

thanks for this boss. I tried all the ports in my laptop but it is not working. I tried it in my wife's laptop it's not detected too. But when I plugged it in my PC and my TV it can easily be detected.

unplug device

Try opening command prompt and entering

set devmgr_show_nonpresent_devices=1

Then

c:\windows\system32\devmgmt.msc

the second one will open device manager where you will go to the top and press View>Show Hidden Devices

then, under Disk drives, select all of the grayed out devices and right click uninstall.

restart and try to connect the drive again

Followed everything you said Boss but still can't detect the hard drive. I tried it again on my PC it's working fine. I'm leaning toward it's a power issue. What do you think?

I doubt it's power if it's consistently working in other devices. Is it possible to back it up, format and move the data back on?

It's possible boss but it's gonna be a lot of work. I'ma try to get a usb Y cable to boost the power towards the hard drive. I'll let you know the result. Thank you!

If it's a 4tb desktop drive with its own power source, a Y USB won't help in that case. Worth a shot if you have a portable one though.
