my external hard drive (transcend 1tb) lags up every time i plug it in. when i plug it in, the light blinks as if it's transferring something and when i click on the drive, it suddenly lags. when i refresh my laptop, the screen suddenly turns green but as soon as i unplugged the hard drive, everything goes back to normal. i know the problem lies in the hard drive as i've tested it on my sister's laptop, (we both have windows 10 os) and the same thing happened, but i don't know what to do and how to fix the problem.
(i'm sorry i don't know technology that well, hence the simple language)
