I need to setup a mp3 server so I can access them from anywhere in my house. I have an old computer to use but I don't want to put all the files on the same harddrive. Instead I was hoping to use a 80 gig hd I had laying around. But what would be the best way to set this up? I want to be able to share this with my windows OS's as well. So would it be best for me to make the second hd a FAT32 and figure a way to share it like that. Or could I just make the second hd the /home partition and share it like I would normally?
Thanks for your time and help.

Format the drive with either Reiserfs or Ext3. Since you are sharing with Windows computers, Samba will need to be installed. Samba will allow access to the Ext3/ReiserFS filesystems, so Please don't use FAT32.

You could mount the hard drive under /home assuming that /home is empty. If there are files/folders under /home, you'll need to move them to the second hard drive before mounting it as /home.

I didn't read that you are sharing these files with other linux computers, but if you are, look into NFS for sharing between linux PCs

Yes I will be sharing it between linux systems as well. I will look into that though. Thanks for the help.
