[PROBLEM] Not starting after reboot

[japumpy]

 Just reporting back. Sorry it's taken a while. I've been struggling a bit with getting the database to build. I've made up 3 SD card images to test. The one that I'm using is a new-ish card that has the latest and greatest MoOde installed. Installation was perfect; I added my NAS to the system (Synology DS918+).
In the default settings, the system is able to mount the NAS and 'see's' the directory where my media is. It parses the first directory completely and then stops. When I try to look at what's been registered I can see the tracks and I can play them ok. However, later when I try and look at the NAS directory, the NAS has disappeared from the system. I've tried to 'REGEN' the database with the same results.
I have also tried experimenting with changing the mount flags with the following values:
-vers = 1.0 - NAS mounts ok but only parses one directory and on subsequent look, the NAS doesn't appear to be mounted.
-vers = 2.0 - as above
-vers =3.0/3.1 - NAS doesn't mount
-vers = default - NAS doesn't mount

Removing vers -  the NAS doesn't mount at all.

Please accept my apologies if I've posted this message in the wrong thread.

You haven't said what protocol you're mounting with, I'm guessing NFS?
Is the Pi's network connection wired or wireless?
Are you mounting the nas by hostname or IP address?

Did you read test your sd card?

My apologies. SMB mounting with IP address always.
I haven't done a read test as yet. Although I have experienced this on a number of cards now some of which are quite new with similar issues.
The connection is wireless at the moment. However, I take your point and I'll try and find a spare port ;-)
Thanks for educating me in what else to specify in future posts.
Cheers!
