June 25, 201214 yr I recently had a redball and the smart report showed the drive throwing off a ton of errors and problems so I decided to replace it. I purchased 2 new WD green 2TB drives and began preclearing. For both cases about 12-15 hours preclear crashes and unraid becomes unresponsive. For both drives the smart reports were showing some problems. I use 2 Supermicro AOC-SAT2-MV8 8-port SATA Controllers and have tried running the preclear off them and directly off the motherboard. I have tried a variety of different sata cables and connectors. PSU: Corsair TX 750 Attached are the smart report and syslog after running preclear for about 15minutes: 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 66 3 Spin_Up_Time 0x0027 171 169 021 Pre-fail Always - 6416 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 171 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 7 Seek_Error_Rate 0x002e 100 253 000 Old_age Always - 0 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 16 10 Spin_Retry_Count 0x0032 100 100 000 Old_age Always - 0 11 Calibration_Retry_Count 0x0032 100 100 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 169 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 166 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 48 194 Temperature_Celsius 0x0022 116 116 000 Old_age Always - 34 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 13 198 Offline_Uncorrectable 0x0030 100 253 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0008 100 253 000 Old_age Offline - 0 My server has been unprotected for some time now and im quite worried I have a major issue here.

June 25, 201214 yr Disk /dev/sdj is filling your syslog with media errors. probably eventually running out of free memory, and crashing the server.

June 25, 201214 yr Author Any idea why that is happening? What can I do? EDIT: Does this just mean I got incredibly unlucky with 2 DOA drives?
June 25, 201214 yr Any idea why that is happening? What can I do? EDIT: Does this just mean I got incredibly unlucky with 2 DOA drives? what does the smart report for WDC_WD20EARX-00PASB0_WD-WMAZA910041 show? Yes, with as many drives as you have, odds are high to experience disk failures.
