problem with sata one disk running at half speed

[Michel-jacobs]

since a while my rn212 runs with disk2 running at half speed. after some googing this seems to be related to the power supply unit. Anybody noticed this as well?

[Sandshark]

Running at half speed?  How so?  The reported RPM is actually halved, or the transfer speed is?

[0d0a]

IT is THE transfer speed Thatcher halves according to kern.log ...

after updating to os 6.9.1 the last lines of kern.log:

support says they got the wrong log files ... They want those from the web interface but that log does not include syslog let alone kern.log

should I be worried? The nas does function (still)

[StephenB]

The log zip file that you download from the web UI certainly includes kernel.log (among other things).

[Michel-jacobs]

yes. i stand corrected. It certainly does. I did not realize this, when one only views the log in the web interface one does not see any kernel messages however!

In the download there are all usual linux logs.

Whenever Netgear asks for the logs, they want the full log zipfile.
