Ultra HDD scanning

[Steve Woodhouse]

I don’t think so, you need to force a rescan. Another reason why I think NAS is a preferable solution for a reasonable sized, evolving library.

Cheers.

How does one ‘force a rescan’?

Many thanks.

Select USB as your input, then when its page opens, choose the three dot menu in the top left hand corner and then “rescan your music server”

Cheers, very helpful.

I’m wanting to try a few things out and do a dummy run with a few folders, so I’m sure about how I want to go about it before doing the whole lot.

I trust a simple-scan will effectively delete anything I’ve changed?

While it’s plugged into your pc when you’re adding folders, I’d delete the wiim_cache folder you see there and that way each rescan will start afresh. Note that this will impact any playlists you’ve set up on the WiiM as a rescan will likely change the pointers to the files in the playlist which could occur even if you didn’t delete the cache as @simbun has reported in the past. It’s not ideal tbh…

How are users getting on with this?

Specifically, if you have your music library on attached storage, then you buy and rip a new CD, take the storage out, add the new rip, and re-attach storage. Does the Ultra find and add the new rip easily enough?

Cheers.

In my experience a forced rescan on NAS music server is much better method, if it's constantly monitoring folders/files the NAS goes MUCH slower. Also if you're mass tagging, mass converting etc, it'll slow down to a crawl.

When you've done what you need ie rip/encode 25 albums then do a rescan.

That's what I do on my PI/LMS system.

Cheers.

If I don’t delete the cache, and just click on re-scan, what happens differently?

Or, put another way, what’s the advantage to deleting the cache?

Many thanks.

I still wouldn’t be sure that it didn’t re-index all files anyway and still screw up playlists you had created on the WiiM - it seems to use an internal index rather than the filename in its playlists. Given we don’t know exactly how it scans (although @simbun again might be able to comment given I believe that it’s based on miniDLNA), I prefer clearing out support files before I do anything of this nature.

Cheers. Playlists may not be necessary.

As I stream much of my music, I’m only going to be putting music I can’t stream onto the drive - the odd track/album not available on streaming, or where my CD is better sound quality.

Thank again.

In the process of setting up my Ultra and had a question about USB hard drives scanning. If I add new folders to an already scanned hard drive is another full scan required? If I switch hard drives is another scan required even if the hard drives have already been scanned? In other words if I alternated between an 2TB and 5TB drives that have been scanned is a rescan required every time there is a switch?

A re-scan is required. It won't take as long as a full scan.

The index is build and saved to a database that is stored on the hard drive itself. If you don't change the contents of each of the drives, this database doesn't need to be updated.

However, the WiiM Home app also caches the index. To be on the safe side I would start a rescan after each switch, it shouldn't take very long.

Thanks so much for your input… much appreciated!
