Library corruption
« on: March 17, 2023, 10:58:55 am »

Has anyone had issues with any of the recent releases where you lose parts of your library?

I am having to complete re-scan my library as hundreds of entries were suddenly lost.  It's a painful process with a library this large and a lesson to make backups frequently.  I've no idea if this is tied to a recent release or something else, but that's all I can tie it to.

I do integrity checks after installing every update and all seems ok to me.

The worst part is that I lost nearly 100% of my particles which will literally take me weeks if not months to fix.

What a mess.  Wish I knew how it happened, but I'll be backing up the library before every new install of an update now.

The total count of lost imported items is > 2000 and I've not finished the TV Shows yet (just started)

I wish I could merge a previous backup and add entries from it missing from latest and drop anything else.  Would save me weeks time.

MC does automatic backups by default. Did you disable that?
Check your .\Documents\JRiver folder. nevermind, that's my folder. I don't remember the default folder. You can see what yours is in Options -> File Location ->Library Backups.

The backups are *.zip.  Use Explorer to find them.

Don't know what's wrong:

Thought it was fixed, but every day I lose entries and have to re-scan drives that I already scanned that have not changed at all.

I'm going to go back several versions of Media Center and hope for the best at this point.

Today I noticed multiple movies are no longer in the library that were there just a day ago....

I doubt that it's the version.  We're not seeing other similar problems.

Try the Import setting for Fix Broken Links.

Is your drive going bad? or a trojan. I had something like that happen a while back. Windows Defender couldn't get all of it, but MalwareBytes worked.

Yes, drives can behave very strangely when they are failing and windows does a crap job of reporting what's going on.

I have used Hard Disk Sentinel for years and like that it gives me useful data on drive health plus early alarms when a drive starts to fail.

Try the Import setting for Fix Broken Links.

This is more likely. Set "Fix Broken Links" to NO or to "protect files..." on all your autoimport settings. If it's set to "YES", then a drive briefly disconnecting or taking too long to wake up can cause MC to remove files from the library.

Will give the suggestions a try.  Another thought occurs:

This is the library on my main media server.

In another room I run MC 30, but often a few revs behind.  When this started happening I recall when I was using MC in the other room to connect to my main library, it started to pop up a message that it was opening the library is "read only" mode. (I think that is what it stated).  I think I had to close that message a couple times in a single session...

Could it be that something on that instance was affecting the library it was connecting to on my main instance?
