Help needed with connection address for external hard drive

Might find some info on this here...

The library isn't on another computer. It's on an external hard drive.

BTW, I don't think any URL will like an ' in the resource, like "JKT's", maybe also rename this resource...

It's not a named resource, that is the system address of the folder on my network

As a check, I would change the system address of JKT's AirPort Time Capsule to a name without an ' (apostrophe). I don't think anything except Apple Proprietary Systems will accept that URL.

That won't help with the address format required by SONOS.

Do you have an iTunes folder inside your music favorites on the Mac you are running the Sonos controller software on? If so, point that iTunes folder to the time capsule folder. Then Update Music Library Now under the Manage menu on the Sonos Controller software.

I run the controller from all my devices and use depends on my location. If I'm downstairs, I use my laptop. If I'm in my office, I use my iMac. If I'm down the garden, I use my phone. All my music lives on an external LaCie hard drive which is connected to my Apple Time Capsule, which also acts as my time machine and as my local network. All my devices, including my central heating and my Sonos system, hook into the local network provided by my Time Capsule. But I am unable to point Sonos to the music folder.

I've tried moving all my music across to my iMac, but when it's switched off I can't access it, which is why I have it all on an external drive. Anyway, there's too much of it to have on my iMac which I need for other tasks, and my old laptop wouldn't be able to cope. But when I try to add the folder within Sonos I am given two options. If I try the "another folder or drive connected to my computer" route, and click 'browse to choose a folder that contains music' and choose my music library folder, which is /Volumes/LaCie/iTunes and hit 'Next' I get the message telling me I cannot select a folder on a network to be shared, and "click Back and choose "on a networked device'" ... so, I do this. I am asked to type the path to the network share. And this is what I cannot fathom because the examples given are: \\MyOtherComputer\Shared\Music and \\MyNetworkedStorage\Shared\Music. If I enter \\Volumes\LaCie\iTunes I am then prompted for a user name and password for the LaCie device. The LaCie device has never had a user name and password. So I skip this bit and hit Next, but then get a Sonos message telling me that the add was not successful. My iTunes can find my folder without any problem whatsoever, but Sonos cannot, and I have wasted so many hours on this and am still no closer to a solution and am only able to listen to a fraction of my music.

You need to enter the network path of the share (which is unique to your network so examples shown by Sonos are not going to work). I have a 4TB RAID redundant NAS and it works fine. I don't know a lot about the time capsule but I think the share path will be something like \\NameOfTimeCapsule\NameOfFolder given what you have said, the network path **could be**

\\JKT's AirPort Time Capsule\LaCie\iTunes

BUT - I recommend you change the name of the time capsule because Sonos (and most OSs) will not like the apostrophe in a network path. You can give it a try but I really don't think it will work with "JKT's" maybe make it JKTsAirPortTimeCap (removing spaces is also recommended).

Also review this post for other share requirements from a Time Capsule as a NAS

Hope this helps.
