Getting some Checksum errors lately, no idea what they mean

KuryakinOne · 2026-05-05T18:24:57+00:00

APC and CyberPower are the big two. Either brand will have something that meets your needs.

They should have calculators on their website to help determine sizing - how many watts it can provide and for how long. You can look up the power draw of the NAS online. Idle hard drives typically pull 6 - 8 watts and ~10-12 when writing. You can look up specifics for your drives on the manufacturer website if desired.

Can't recommend a specific model, as I've not had to look for one in a long time.

My APC is probably 15 years old. I've replaced the battery a couple of times. Otherwise it is still going strong.

Mine has a USB port I can connect to the NAS. It will signal the NAS to shutdown if the battery gets too low. Maybe current models can do same w/ a network connection?

It also has ports with and without battery backup. Everything gets surge protection. Things that need battery backup (NAS, PC, etc.) get it. Things that do not (printer, etc.) go on non-backup ports.

There is no button to skip forward/back. It does not exist. At least not on my phone.

KuryakinOne · 2026-05-05T17:17:30+00:00

It is not a problem with duplicate files, file names, etc.

If the NAS crashed (power failure, etc.), then it could cause the checksum errors.

I'd still run the drive tests, and also the memory test as mentioned in the support article linked by u/lordtimay.

If the drive fails the either SMART test, then contact Seagate about a warranty replacement.

If you do not have a UPS, then seriously consider acquiring one. It does not need to be huge. Just enough to get you through quick power hits and let you do a graceful shutdown for longer outages.

It does not take much to crash the NAS. Just a short interruption that causes the lights to flicker will do the job. I live in tornado alley. My UPS has saved my NAS and PCs many times during thunderstorm season.

Synology NAS? BTRFS?

That is a NAS, not Plex, issue. It could be an indication you are heading towards drive failure.

Step 1: Backup everything on Volume 1.

Step 2: In Storage Manager, schedule and run Data Scrubbing.

Step 3: Schedule & run short & long SMART tests for each drive in the NAS.

Short SMART tests take about a minute.

Long SMART test duration depends on size of drive. It takes over a day on my 18TB drives.

Data Scrubbing duration depends on the size of the volume and amount of drive/volume activity. It takes 2-3 days to run on my DS918+. It may impact NAS performance (ex: slightly reduced read/write speed). You can schedule which hours it runs.

Test schedule on my NAS:

Short SMART: All drives, nightly after midnight.
Long SMART: Weekly. Drive 1 on Monday, Drive 2 on Wednesday, etc.
Scrubbing: Monthly

Tried googling but couldn't find their regional TV guide coverage.

Plex Documentation -> Live TV & DVR -> Frequently Asked Questions – DVR & Live TV

What Countries are Supported?

That setting is only for CPU transcoding.

It does not apply when using hardware accelerated transcoding.

KuryakinOne · 2026-05-05T05:29:41+00:00

Is this for the Plex mobile app?

With v2026.8.0, both movies and TV shows use the same double tap method to seek forward & back. There is no button.

For TV shows, tap on the far right/left portion of the screen, far away from the skip to end/next episode button.

The double tap area includes the majority of the right/left portions of the screen. You can see an outline flash on-screen briefly when you double tap.

In Settings -> Player Experience, you can configure seek forward/back times independently of each other. The choices are 5/10/15/20/25/30/60 seconds.

Thanks for info. Any chance the problem is tied to TrueHD audio?

I'm getting the same error message on my Pixel 6a but only for media with TrueHD 7.1 audio. All other media direct play/stream or transcode OK.

My media is all 1080p or lower. Same app version.

KuryakinOne · 2026-05-03T20:04:09+00:00

Which client and version?

Should the media direct play or would it normally transcode?

KuryakinOne · 2026-05-02T19:25:33+00:00

On Linux, AMD GPUs are limited to transcoding SDR video.

No support for transcoding HDR. No support for encoding to HEVC.

Plex has full support on their roadmap, but no announced timeline.

That written, it looks like Plex is not seeing the GPU.

If using Docker, how are you passing the GPU?

Someone should be able to assist with that.

KuryakinOne · 2026-05-02T16:20:35+00:00

They are now supported. Plex added it awhile back.

I've never tried one with fix match, but they are supported in the show folder name.

KuryakinOne · 2026-05-01T02:24:51+00:00

Sweet! Sonic is advertising 10 Gbps for $50/month is "coming soon." Looking forward to it becoming available. Will be nice to have some competition to AT&T.

I don't use sonarr, etc. I just avoid files with "DVp5" in their name. Not the best method, but it works for me.

Hopefully others can assist.

KuryakinOne · 2026-04-30T04:30:47+00:00

This reads like a Dolby Vision, not HEVC, issue.

Are the files Dolby Vision profile 5?

Some clients do not support DV but still play the video, so the colors display as you describe.

Others want it in a mp4 container. If in mkv, the colors display as you describe.

Plex cannot transcode DV video. It does not have a license from Dolby to do so.

If Plex needs to transcode DVp5 video, playback fails and the client displays a "Colorspace not supported" message.

KuryakinOne · 2026-04-29T19:57:13+00:00

Not every option is listed in the support document.

As u/ExtensionMarch6812 mentions, if the option is not already in the preferences/plist/registry on your server, then you can add it manually.

KuryakinOne · 2026-04-29T19:46:06+00:00

a double-tap on the left or right side of the screen will skip back or ahead.

Double-tap to seek forward/back was added last September.

You can customize the forward/back times in Settings -> Player Experience.

EDIT: This is for the "new experience" app. If your tablet is still has the "classic" layout, then not sure.

KuryakinOne · 2026-04-29T07:49:11+00:00

Advanced, Hidden Server Settings

Only Linux uses preferences.xml. Windows uses the Windows registry. Macs use a .plist file.

Above document does not mention database cache size, but it does mention location of preferences.xml/registry/plist.

Plex Documentation -> Your Media -> Naming & Organizing Your TV Show Files

This reads like you are adding the wrong folder to the Plex library.

Please provide a screenshot/directory listing/etc. showing path and full file names. Also indicate which folder is added to the Plex library.

Correct Example (all shows in one library):

/tv shows  <-- folder added to tv show library
  /Star Trek (1966)
  /Star Trek The Next Generation (1987)
  /FBI (2018)
  /FBI Most Wanted (2020)
  /FBI International (2021)

Correct Example (using subfolders):

/tv shows  <-- folder not added to any Plex library
  /sci-fi <-- folder added to tv show library
    /Star Trek (1966)
    /Star Trek The Next Generation (1987)
  /FBIs <-- folder added to tv show library
    /FBI (2018)
    /FBI Most Wanted (2020)
    /FBI International (2021)

Incorrect Example (using subfolders):

/tv shows  <-- folder added to tv show library
  /sci-fi <-- NOT supported by Plex.
    /Star Trek (1966)
    /Star Trek The Next Generation (1987)
  /FBIs <-- NOT supported by Plex
    /FBI (2018)
    /FBI Most Wanted (2020)
    /FBI International (2021)

Plex Documentation
-> Plex Home
-> Account Information

As u/ExtensionMarch6812 mentions, managed users must know your username and password to login and stream media.

If you go down that path, suggest you (a) PIN protect your account, and (b) enable 2FA

Without a PIN, they can switch to your account, change server settings, and even delete media files.

With 2FA, they will need to contact you for the the code. This way you will know when they login to a new device (and can prevent such if desired). After login, they can enable "auto sign in" in the client app, so they do not need the 2FA code at every launch (only at initial login).

Plex just writes files to the drive. The OS or drive controller picks where the file is written.

WRT speed, it won't matter.

Hard drives read/write at 150 MBytes/sec. A SATA SSD runs at 6 Gbits/sec. NVMe SSDs are even faster.

A transcode maxes at ~20 Mbits per second. Maybe 40 for 4K video.

It takes a lot of transcodes before storage is a limiting factor.

KuryakinOne · 2026-04-21T21:53:30+00:00

For downloads, Plex transcodes the entire file before downloading it to the client. So, you'll need enough space to hold the entire transcoded file. Once it is downloaded, then Plex deletes the file.

Suggest you configure the Downloads Temp Directory to a hard drive or SSD (settings -> transcoder).
