Hi all,
i just precleared a Seagate 4TB (ST4000DM000) on my test unRAID (VIA C7 - 800 MHz - 512MB Ram - SATA1 150MB/s). It take a long time for 3 Cycles, but I think the reason is the old test hardware.
I'm a little bit confused about the value "near_tresh" in the result:
Spin_Retry_Count = 100 100 97 near_thresh 0
End-to-End_Error = 100 100 99 near_thresh 0
Here are the complete results:
