External hard drive Power pack missing

Hi
I have a oldish WD 1TB External Hard Drive WDBAAU002OHBK, went to check on some files I have on it, but don’t seem to be able to find the transformer for it !, not used it for quite awhile, does anyone know what the voltage is for this this drive to get another transformer for it ?.
Regards
Spike
