Hey.. I've been working with this problem for quite a while now and have come to no resoultion. To begin I need to say that my Homegroups is working great. Have Windows 7 installed on a laptop and a desktop and are able to see the music, documents, pictures, and videos libraries fine. The problem is when i try to "Share" an external hard drive ( H: ) on the homegroups it will only open a new window of the sharing tab of the properties for the drive. I even tried adding H: to the music library (since the drive is full of music). The H: drive will show up locally in the music library on the desktop but will not show up when viewing within the homegroup from othe other computer. I made some screen shots to better understand what I am talking about.. First, attempting to add folder to homegroup with read/write access: Second, when I choose Homegroup (Read/Write) all that pops up is the sharing menu for the H: drive.. not too much help seems to be there..: http://www.writetobyte.com/windows7help/two.JPG (had to make link. i'm limited to 4 images?) Ok.. Didn't work... Now this is attempting it by adding H: to the Music library: Locally, on my desktop in the Music Library I see my H: drive: But on my laptop no such success.. it just doesn't show the H: drive at all: If anyone could help it'd be greatly appreciated!
