I experienced a high-pitched squeaking sound coming from my Tablo Quad Legacy. After trying several troubleshooting steps, I measured the power supply’s output voltage with a multimeter. The reading was only 8.6V, significantly lower than the expected 12V. I replaced the power supply with a new 12V unit, which completely fixed the noise. I hope this information is useful to others facing the same issue.

Interesting - did it squeak all the time, or only periodically? Mine emits a med/high-pitched (not quiet) squeak periodically, which I’ve sort of correlated roughly to the times when a recording might be starting. I kind of guessed it was the drive spinning up or something, but never really investigated as it is short lived and not too irritating
Thx!
First intermittent then regular. Just search “how to test power supply with multimeter”. There are multiple videos. It’s a simple and fast test.
