I recently recived an error notification on one of my pool drives (which is an SSD) and I'm not sure what to make of this if it was a once off or if something else may be an actual issue (Normally if its an SSD drive about to die they just drop off)

Where would I be able to see the cause of this issue or what may have caused it or how to clear the notice and fix the issue?

(The CRC error I believe was fixed when I replaced the cable some time ago I dont believe that's recently changed)

Please post the diagnostics

Normally if you click on the orange icon it gives you more information.

Note that if the CRC type error count has increased that might explain the warning.

@JorgeB they are in the original post (under the image) https://forums.unraid.net/applications/core/interface/file/attachment.php?id=381921&key=8a90b67e160ce9fe935e3e1f456ddeaa

@itimpi It seems to show the same info as there was Read/Write errors but I'm not sure if its due to a drive about to die or something else as it was just one of the drives as shown in the first screenshot

Below is the expansion of the read/write errors,

The numbers havent changed since they appeared but I'm not sure if I need to run something to validate if the data is still ok (as they are mirrored)

Do I just click the reset button and move on unless it comes up again or is the drive on the way out or something else caused this one drive to throw errors,

Those stats suggest one of the devices dropped offline in the past, scrub the pool, and if there are no errors or all errors are corrected, reset the stats and keep monitoring, if it drops again, replace the cables for that device.

will do, so its first fix if it happens again is replace the Sata cables yes? Drive itself isn't showing signs of failing?

Ok so the drive seemed to clear correctly it seems,

Will clear the error and keep a pulse check on it
