Pre-Clear Drive Stopped - errors in log?

[eric90000]

Hi guys,

 

I'm brand new to Unraid and just started using my first trial key. I left a pre-clear disk running overnight and when I logged back on today I noticed it was no longer running. When I clicked start again it told me I can resume the previous instance, and it did indeed resume at approx 82% pre-read. For info this is a 12tb WD Elements drive connected via USB and using the included PSU. Once it passes pre-clear I will be shucking it and connecting it internally via SATA.

 

Can anyone tell me why this stopped in the first place? Looks like the first error was a 'tower kernel: Sleep', so I'm thinking maybe it was an issue with the drive going to sleep? Here is the relevant section from the log. Error messages highlighted in red.

Best bet is to use the appropriate docker or plugin support thread, depending on what preclear version you're using.
