Hi, it’s not NAS specific. It happens to me on my locally attached USB drives.
Anyway. after all these responses, I think we can rule out user error/corrupt files. This is a bug introduced in the last update.

Agreed, no NAS here, only “regular” external drives.
For what it’s worth: for me it only appears to happen when moving files from one hard drive to another. If the files are on the same drive and dropped into the Roon library folder on that drive (in which case Windows needs virtually no time to move them) the errors do not occur.
Hi everyone,
Thank you for the report. The support team is gathering diagnostic logging to investigate more closely. We’ve merged all reports of this thread into a single tracking thread so you can receive updates.
We recognize this is agnostic to the local file location and format for those affected. However, for due diligence, however, we’d like to request a copy of a local file exhibiting the symptom from those who haven’t uploaded already.
Please share a FLAC file here: Media Uploader
We’ll be activating logs in the meantime, so please reproduce the error if you’re willing and share a timestamp here.
Thanks for your patience and we’ll respond soon with more information.
+1 also getting the ‘I/O failure’ when adding files to Roon library. Files work when loaded directly to EverSolo DMP-A8. Also, works from Plex server.
Issue seems to resolve itself with a reboot of the Roon Server. I’m running my server on a 2018 Mac Mini (Core - i5).
Hi, any updates from the Roon support team, regarding my missing songs problem?
Hi everyboda and a happy new year.
I wasn’t at home during new years eve until Jan 2.
I shutted down ROON and all servers during that time.
Yesterday after rebooting same problem as before. Bute after some minutes the files showing i/o error were shown correct. Without having anything done.
Great start into new year
That is interesting, I have been restarting roon server to fix - which presumably prompts a rescan. So probably a rescan fixes.
I tried 3 or 4 times to rescan the specific album without a result.
Shutting down the file-server (QNAP NAS 8 bay) and the ROON-box (ASUS Intel I5, WINDOWS 11pro) seems to work fine.
The same here. Moving the music folder around sometime helps. But is should not happen at all!
A rescan does not fix for me either. Stopping the Roon Server then restarting Roon does fix the issue for me.
Still an issue for me, either whole albums or single or multiple tracks on albums. Restart not corrected. Not sure I understand the need to upload the files for Roon to assess, but will send one up, not all.
I shutted down all systems not only ROON-Software. The Windows-box, the file-server and the mirror-server have bee completely down. Everything seems to be fine after restarting all boxes (whole boxes not only ROON-server Software!!!)
Hey @Peter_Singleton,
Thanks for your patience so far! From your ROCK diagnostic report, we’re seeing a failure with your Roon Server when accessing specific directories within the drive. On reason this could happen is a lack of permission. If you navigate to your Roon Settings>Storage, are there any errors around your watched folders?
This format should be supported - can you upload an example file to our uploader below for further examination?

I also noticed you’re running EarlyAccess on your ROCK, are you also running EA across your remote devices as well?
We’ll be on standby for your reply, thanks! 
Hi, many thanks for your reply. I ran a disk check on my music hard drive and no errors found. I copied a few more CD’s and more tracks were added to the skipped folder.
I wasn’t aware about the Early Access. My original NUC rock failed and I replaced it with one bought of eBay. Can I easily change the ROCK software to the official version?
Many thanks
Peter
I am having the same fault (i/o error) when importing local files to my Roon server (Taiko Audio Extreme). It happens EVERY time I import files - both FLAC and DSD. A complete reboot will solve this. I have imported 1000s of tracks to my server and I have never seen this error before, so it must be a bug in Roon - possibly in the latest update.
Would be nice if Roon could fix this asap, than you.
Instructions (and a link for the download file needed) for moving your ROCK/NUC system from Early Access to Production are given here:
Thanks for that Geoff.
I converted my rock back to production software and the majority of the skipped tracked are now within the albums.
I added a few more ripped CDs and noticed there were more songs tracks in the skipped folder. However, when I restarted the ROCK, those tracks had moved to the album files.
It seems I have to restart the ROCK each time I rip a CD. I never had to do that before, and I have over 3000 albums.
It is still happening quite regularly.
I just uploaded a file. Can send more if you need.
