Re: Usb external hard drive disk with extension cable
An external hard drive draws significantly more power than a usb pen drive, so the extension cable may have enough resistance to have reduced the power delivery enough to stop the drive functioning correctly.
Firstly, make sure you're actually plugging the cable into a USB 3.0 port on the laptop. These deliver more power typically than their USB 2.0 counterparts. (ports are generally blue or yellow internally)
It might be worth buying a complete new cable, can you show us an image of each side of the cable? There are 4+ different standards which I can thik of so it's worth knowing what we're dealing with.
