Problem about indexing files between partitions

Problem about indexing files between partitions

I'm here for talking to you about a problem. First of all sorry for being
noobish but I just installed Ubuntu this night. Anyhow, here's the
problem: I have my PC with a double boot Ubuntu+Windows 8 and I installed
Ubuntu in a secondary partition in my 500gb hard drive. In the other
partition there are my files such as music, downloads etc for my windows
hard drive ( I have an SSD where is stored 8 and an hard drive where I
have my files and Ubuntu). So now I'm trying to use my music with
banshee's library system and at the first time that I used that library I
got no problems. Now that I reboot Ubuntu when I try to play the music the
software just says that he can't find the file ( I suppose that Ubuntu
gets some time before loading files from other partitions but dunno... ).
And the same thing happens with my Dropbox folder withc is in the same
partition of the music one. So, Is there a way to fix this annoying
problem or it's just something that I should ignore ? Anyhow, Ubuntu 13.04
is installed on ext4 and my file partition on ntfs. For better
understanding here a little graphic explanation about my partitions:
C: -> Windows 8 D: -> Ubuntu partition (E:) My files Basically the file
hard drive has two partitions Sorry for my English mistackes but I'm
Italian
Thank you for the attention given to me and have a nice day
