This is an interesting topic that pops up now and again.
Subsonic doesn't seem to always play well with NAS and/or external drives. Additionally, if the drives isn't formatted as an NTFS drive there can be problems.
I always make any external storage that I'm going to access with Subsonic a network share, such as: "\\Music"
For some reason this seems to work the best and avoid problems. The one thing you have to remember is to give the Subsonic service the proper logon account so that it has permission to read the share.
This shouldn't apply to an external drive that shows up as a local drive on the host PC, but this isn't the first time I've seen this reported.
I'm not a big fan of a NAS or external drive due to their poor thermal properties that generally cause early failure. With cheap big drives available I much prefer to just add another internal drive. It's usually a cheaper and more reliable option.
Much the same analogy as in the old days when everyone was buying tape back up drives that were slow, expensive and less reliable than just adding a second hard drive. never could figure out that logic either. With NAS and external drives carrying a premium, I just can't make sense out of buying them when gigabit lan makes any drive accessible on the internal network. I do have one 2.5" external that i use as the server back up drive for my WHS 2011 C: drive and it also comes in handy on ocassion if I want to mail a large chunk of data to someone, but that hasn't happened in ages.
