OK I pre-cleared this drive for 3 more cycles, here are the results: Sep 18 19:08:45 Tower preclear_disk-finish[937]: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE Sep 18 19:08:45 Tower preclear_disk-finish[937]: 1 Raw_Read_Error_Rate 0x002f 197 195 051 Pre-fail Always - 1536 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 3 Spin_Up_Time 0x0027 100 253 021 Pre-fail Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 4 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 180 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 10 Spin_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 11 Calibration_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 3 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 2 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 111 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 10 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 21 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 Sep 18 19:08:45 Tower preclear_disk-finish[937]: 200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 49 What happened to the 17 Current Pending Sectors from my first pre-clear? I was expecting to see them under Reallocated Event Count this time around. What's the verdict, is this drive too flakey to go into the array?

Still in the 2nd of 3 more cycles of pre-clear, but I'm seeing one heck of a lot of errors in my syslog now, here's a sample: Sep 17 04:57:23 Tower kernel: ata4.00: failed command: READ DMA EXT Sep 17 04:57:23 Tower kernel: ata4.00: cmd 25/00:08:c0:cf:14/00:00:94:00:00/e0 tag 0 dma 4096 in Sep 17 04:57:23 Tower kernel: res 51/40:00:c7:cf:14/40:00:94:00:00/e0 Emask 0x9 (media error) Sep 17 04:57:23 Tower kernel: ata4.00: status: { DRDY ERR } Sep 17 04:57:23 Tower kernel: ata4.00: error: { UNC } Sep 17 04:57:23 Tower kernel: ata4: hard resetting link Sep 17 04:57:24 Tower kernel: ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 17 04:57:24 Tower kernel: ata4.00: configured for UDMA/133 Sep 17 04:57:24 Tower kernel: ata4: EH complete Sep 17 04:57:27 Tower kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Sep 17 04:57:27 Tower kernel: ata4.00: edma_err_cause=00000084 pp_flags=00000001, dev error, EDMA self-disable Sep 17 04:57:27 Tower kernel: ata4.00: failed command: READ DMA EXT Sep 17 04:57:27 Tower kernel: ata4.00: cmd 25/00:08:c0:cf:14/00:00:94:00:00/e0 tag 0 dma 4096 in Sep 17 04:57:27 Tower kernel: res 51/40:00:c7:cf:14/40:00:94:00:00/e0 Emask 0x9 (media error) Sep 17 04:57:27 Tower kernel: ata4.00: status: { DRDY ERR } Sep 17 04:57:27 Tower kernel: ata4.00: error: { UNC } Sep 17 04:57:27 Tower kernel: ata4: hard resetting link Sep 17 04:57:27 Tower kernel: ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 17 04:57:27 Tower kernel: ata4.00: configured for UDMA/133 Sep 17 04:57:27 Tower kernel: ata4: EH complete Sep 17 04:57:30 Tower kernel: ata4.00: exception Emask 0x0 SAct 0x0 SErr 0x0 action 0x6 Sep 17 04:57:30 Tower kernel: ata4.00: edma_err_cause=00000084 pp_flags=00000001, dev error, EDMA self-disable Sep 17 04:57:30 Tower kernel: ata4.00: failed command: READ DMA EXT Sep 17 04:57:30 Tower kernel: ata4.00: cmd 25/00:08:c0:cf:14/00:00:94:00:00/e0 tag 0 dma 4096 in Sep 17 04:57:30 Tower kernel: res 51/40:00:c7:cf:14/40:00:94:00:00/e0 Emask 0x9 (media error) Sep 17 04:57:30 Tower kernel: ata4.00: status: { DRDY ERR } Sep 17 04:57:30 Tower kernel: ata4.00: error: { UNC } Sep 17 04:57:30 Tower kernel: ata4: hard resetting link Sep 17 04:57:30 Tower kernel: ata4: SATA link up 3.0 Gbps (SStatus 123 SControl 300) Sep 17 04:57:30 Tower kernel: ata4.00: configured for UDMA/133 Sep 17 04:57:30 Tower kernel: sd 4:0:0:0: [sdd] Unhandled sense code Sep 17 04:57:30 Tower kernel: sd 4:0:0:0: [sdd] Result: hostbyte=0x00 driverbyte=0x08 Sep 17 04:57:30 Tower kernel: sd 4:0:0:0: [sdd] Sense Key : 0x3 [current] [descriptor] Sep 17 04:57:30 Tower kernel: Descriptor sense data with sense descriptors (in hex): Sep 17 04:57:30 Tower kernel: 72 03 11 04 00 00 00 0c 00 0a 80 00 00 00 00 00 Sep 17 04:57:30 Tower kernel: 94 14 cf c7 Sep 17 04:57:30 Tower kernel: sd 4:0:0:0: [sdd] ASC=0x11 ASCQ=0x4 Sep 17 04:57:30 Tower kernel: sd 4:0:0:0: [sdd] CDB: cdb[0]=0x28: 28 00 94 14 cf c0 00 00 08 00 Sep 17 04:57:30 Tower kernel: end_request: I/O error, dev sdd, sector 2484391879 Sep 17 04:57:30 Tower kernel: Buffer I/O error on device sdd, logical block 310548984 sdd is the disk I'm preclearing.

Thanks guys! Running 3 more cycles on that drive now.

First off, thanks again to Joe for a great script! I just precleared 2 WD20EARS drives (with pins 7 and 8 jumpered). I precleared them simultaneously using separate screen sessions. They both successfully precleared, but gave me the "Offline data collection activity was suspended by an interrupting command from host" warning. I gather from reading posts in the forum about it, I shouldn't need to worry about this. I am a little worried about the Raw_Read_Error_Rate and Current_Pending_Sector values for one of the drives though: Sep 12 14:26:23 Tower preclear_disk-finish[30093]: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 1 Raw_Read_Error_Rate 0x002f 197 195 051 Pre-fail Always - 291 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 3 Spin_Up_Time 0x0027 100 253 021 Pre-fail Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 4 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 32 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 10 Spin_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 11 Calibration_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 3 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 2 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 19 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 17 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 198 Offline_Uncorrectable 0x0030 100 253 000 Old_age Offline - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 Sep 12 14:26:23 Tower preclear_disk-finish[30093]: 200 Multi_Zone_Error_Rate 0x0008 100 253 000 Old_age Offline - 0 Are my worries about this drive warranted?
