l purchased a WD 650gb external hard drive a while ago, l've had no problems with it, so l bought another WD 1tb to use as an extra backup for my pics as l take alot of photo's. When l have the 1tb plugged in and then l turn my computer on it runs so slow it nearly stops/freezes, it is so bad that l can't use the computer,l have to unplug the hard drive turn the computer off then on again for it to work properly. l got in touch with WD who told me to do an RMA, they replaced it with no explanation and a completely different hard drive, (l had an elements they replaced it with the book) this one does exactly the same, does anyone have a solution as WD will not answer my emails. Can anyone recomend a good external hard drive l'm on windows 7. Thanks
The 650 is plugged in all the time and works ok, the 1tb does have it's own power supply, l don't know what the pc is busy trying to do, when l try to use it the screen goes a white colour and freezes. l have just been told to start the pc first then to plug in the hard drive and it seems to work fine. Thank you both for your help.
