NAS/Disk hibernation/spindown

[NZ_DAC]

I have a PC (Windows 7) on my home network running GB-PVR (1.4.7) configured to record to its local hard drive.
I also have a NAS attached to my home network (Synology DS409+), with its disk configured to spindown/hibernate after 20 minutes of inactivity.
I have listed one of the NAS directories in the GB-PVR 'Video Library Directories', and suspect that this is causing the disks in my NAS to wakeup before and after every recording.
I reference the directory 'C:\Users\NAS_Library\NAS', which is a link to my NAS at \\192.168.x.x\NAS.
From the NAS log I can see that the disks get woken up a couple of minutes before a recording starts, as well as being woken up around 10 minutes after a recording completes - which relate directly to my GB-PVR 'Recording Padding' of 2 pre-show and 10 post-show minutes.
I really dont want to remove the reference to my NAS disk from the 'Video Library Directories' as my wife finds it very useful to quickly navigate to my archived recordings.

Question: Is there an entry I can make to the GB-PVR configuration file to stop it waking up the NAS disks before and after every recording.

What happens if you just have the NAS added to the video library as the network location?
My NAS & other drives don't wake when a recording is starting, just the drives which are needed.

do you have nas mapped as a drive letter? if so windows will access it everytime it scans for available disks...
better way is to remove drive letter mapping, and just add net path to video library..[\\server\drv\path]
then it should only access it when going into video library...

First of all sorry for the delay ... I wasnt aware I had any replies, must check my mail settings !
I dont have the NAS mapped as a Drive Letter, as I found the SMB protocol kept waking the disks up.
I have tried the NAS added to the video library as both a virtual directory (ie a directory 'C:\Users\NAS_Library\NAS' linked to my NAS at \\192.168.x.x\NAS) and as a direct reference to \\192.168.x.x\NAS ... both seem to behave the same.
I use SlimmGBPVR, so will try removing that for a while ... maybe that is causing the issue...

[NZ_DAC]

I think I found at least one of the issues ... it is related to the 'Recordings' section of GBPVR, not the 'Video Library' section.
I had used a Transcoder to archive (move) some of my Recordings from my local directory (V: Drive) to another directory linked to my NAS (C:\Users\NAS_Library\NAS\...) while keeping all the recording information, descriptions, channels etc - it appears that GBPVR must scan all its Recordings when it starts up, or at least when you perform any recording function.
I have temporarily renamed all Recording links to the NAS directory (Changing C: with a non-existent X using the below code, and things are looking hopeful - after which I will try to re-setup my SlimmGBPVR and Video Library links.

SQLITE> UPDATE recording_schedule
SET filename = 'X:'||substr(filename,3,999)
WHERE filename LIKE 'C:\Users\NAS_Library%';

So then this raises another question of whether I can stop GBPVR scanning the 'NAS' files within its 'Recordings' ... I'm not sure why it does this, so unsure as to whether this request makes sense.

It's part of the config option for removing recordings from the database if they cannot be found.
If you NAS goes offline for whatever reason, then GBPVR would remove them from the database as recordings as it could not find them (unless you have set that option in config.xml to false)
(Autoremovemissingrecordings I think)

Don't know if you can stop it scanning, but see if setting that to false helps.

[NZ_DAC]

Yes, I have "AutoRemoveMissingRecordings" set to false, as if it is set to true then (as you have mentioned) if the NAS is powered off, and GBPVR is started, then it removes all the 'Recordings' that reside on the NAS - which is not what I want.
What I dont know is why (with the parameter set to false) GBPVR is still scanning the files, as it is this scanning which is constantly waking my NAS

On a similar note, I have noticed that if you try to play a file which refers to a file on an offline disk, then it obviously wont let you - however, once the disk is onlined, GBPVR still wont let you play the file you had previously attempted to play - the only options it gives you is 'Delete' and 'Close'. Its as if when you first attempted to play the offline file GBPVR marks it as permanently lost and will not ever attempt to play it again...
