Good evening, I have an external hard drive from HP (hp pd500a) and my new laptop is unable to detect it. The drive spins, but the PC doesn't find it. It works perfectly fine on my old laptop and my parents' desktop. I checked in disk management and tried it on all 4 USB ports. I would like to know if there is a solution, as I find it strange that it works on other laptops and desktops but not on my new laptop.
Thank you in advance for your help.

Good evening,
Your "new laptop" doesn't have enough power to run an external hard drive from the USB port; you need a "Y" cable that plugs into two USB ports to double the current.
Something like this https://www.google.fr/search?q=cable+USB+en+Y&tbm=isch&tbo=u&source=univ&sa=X&ei=0Wm9VObHAdPqaInhgkA&ved=0CEoQsAQ&biw=1680&bih=914
Otherwise, you need a hard drive with its own power supply.

Yet it's a laptop that was released not long ago.
But what I don't understand is that I hear it running, so it's powered on. But does it also need extra power for detection?

Hi,
It's not always the same depending on the phone; we don't know... check the manual... otherwise, it's downloadable from the manufacturer's website..
It's unnecessary to get your USB drive working... especially if a USB stick works on the port.
Often, it's the "Delete" key or F2 right at the beginning of the HP logo.

Go to the BIOS settings and check if the USBs are powered + connected or just connected; otherwise, you can try using a cable with 2 USBs

It varies on each motherboard, often it's F12 or Escape, but if you can send me a photo of the screen before Windows starts, I could probably help you.

Almost, actually by default USBs are powered at low intensity which is enough to detect USB sticks and most external hard drives (at 3200 RPM); however, some external hard drives come with a Y cable because they run at 5200 RPM or higher, which requires more "power" to be powered and detected (for example, it may be sufficiently powered to run but not to be detected, like in your case). But you can also change the USB power settings in the BIOS settings.

Good evening, try this:
1) Right-click on Computer > Manage
2) Go to Disk Management
3) Your hard drive should be there (check the size of the disks), yours probably doesn't have a letter assigned to it.
4) Right-click on it > Change Drive Letter..... > Add > Assign the following drive letter > Choose the letter you want.
Normally it should work after that.
