I currently am using a HP6620f pc with two hard drives installed. The C: drive has the OS and programs and misc. The other hard drive I use as a data drive and it holds the torrent files from two different Utorrent programs. The data drive is 2tb and about full. I want to install another 2tb drive. I have slot and plug room on the motherboard so instillation should not be a problem. My concern is that I would have to change the downloaded file destination drive in the two Utorrent programs so that any new torrent files would be routed to the new drive . If I do that would people wanting to upload torrents from the old drive still be able to see their availibility and upload them. Hope I have worded this so its understandable. Thanks for your help.
