external hard drive not detected

[nd2014]

So i connected my external hd to my laptop. There was a sound signalling that it was connected but when i opened my computer , i didn't find my hard drive. The light is also not blinking

Hi

Did it work there previously?

On same USB ports ?

Today I had a USB 3.0 1TB 2.5" drive which connected to front case ports but not rear ports (all USB 2.0 on a Dell midi tower)

Probably due to available power not enough

Does it connect to other pc's ?

Is it a 2.5" or 3.5" drive

Look in device manager?
Anything shown ?

Hi

After formatting c: and re installing windows did you re install the motherboard chipset drivers ?

Some times there are also USB drivers
Check on laptop manufacturers web site

External 3.5" drives always need an external psu
While most 2.5" drives can run on power from USB port
