Hello users.

I dont know what else to do here. I have a samsung portable harddrive. Its the hdd with just the usb cable, no power cable included. anyways, i recently bought me a pc from a friend but when i plug it in the rear of the pc (which is the only ports working), windows just keeps giving the connecting / detection sound over and over or other times it give the sound and then the disconnect sound and it repeats itself. ive learned that when you use a shorter cable, it actually detects and opens but then it disconnects again. i dont have this kind of problem at all when i plug it into a laptop. Strange thing also is that when i plug in a hdd with the power cable, it reads perfectly. Could it be my power supply or what?

I need help here on this one please.

thank you

It could be that the motherboard is not capable of supplying the voltage the drive needs to function properly. Is the drive USB 1,2or3? What version is the USB on the board?

is this portable hd the large type (3.5 desktop hd) or the small type (2.5 laptop hd) as i have found the large type needs a power supply, if it is the large type you should have had a power cable with it.

is your desktop older than your laptop, as Baltboy has said maybe the m/board on your desktop is not capable of supplying the power to it.

also sometimes the usb cable has 3 usb plugs on one is for extra power when also plugged into your pc.
