Help! My PC Can't Recognize External Drive

Hi everyone, I bought a new 1TB Western Digital Elements external hard drive last week Monday purposely to store media files. The store attendant tested it and it was working alright. I brought it to the office, plugged it into my office laptop and it was recognized by it. I even copied some movie files on it and sent it home. I plugged it to my home desktop pc but it did not recognize it. It showed neither in My Computer nor Device Manager. So I did a little research and came to the conclusion that the problem had to be due to lack of partitioning. So I decided to partition it the following day in the office. I downloaded Easeus Partition Master as was recommended by some sites I came across in my research and tried to partition it. The partitioning failed. After several tries, the laptop which had hitherto recognized the external drive couldn't recognize it anymore. It was no longer even showing in Device Manager. After reading over this for several days, I check Disk Management and the drive was there. The long and short of it is, I've tried several approaches to get the drive formatted and partitioned so I can get the PCs to recognize it but all have failed. I'm really at my wit's end now. I've searched several places on the net but none have been helpful. The hdd shows in Disk Management as healthy etc but I can't access it for the purpose I bought it. I'm really gone beyond frustrated now. Could anyone please help? I'm just an average computer user by the way. Not technically sound with it.
