I was looking into getting an external hard drive and I see for example cnm core 120gb which is connected to pc by usb which also powers it. My question is can the pc power the external drive without causing a problem as I see a lot of external hard drives which have there own power source?

External Hard Drives are better with their own power source.

If you just want it to use at home I would recommend one with it's own power supply. If it has to travel with you then the USB powered ones are usually smaller and lighter and so more convenient.

The Drive you are looking at will be a Laptop 2.5 inch drive, this is normal way to power them. Those with there own Power supply are the Full Size Desktop Drive and do need a Power Supply

My previous USB H/D had a separate power supply and you had to remember to turn it on before booting up, I have my mail store folder and other data, video and music etc. on my external H/D in fact I only have very little other than my O/S and programs on my C drive. My new one is powered via the USB connection and I have not encountered any problems with it. I would suggest you obtain as larger capacity one as you can afford, a 120Gb one I don't think is large enough. My original was 232Gb and my new one is 1 Tb.

I have 3 WD 1TB USB powered drives (they use 2.5" HDD's) If I want to use more than one at a time, I use a powered hub.;
