Dear Joe, thanks for your quick reply That is nice to hear I will do this. Sorry I do not understand the meaning of this. Both disks started with the same values: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 7 Seek_Error_Rate 0x000f 100 253 030 Pre-fail Always - 5662 The first disks "Seek_error_Rate" didn't change after 3 cycles preclear. The second disk's value changed as mentioned above. Kind regards

Hi all, I just finished clearing my 4TB Seagate. I'm little confused about the value in the report: ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VALUE Seek_Error_Rate = 60 100 30 ok 1119619 In my first 4TB Seagate, this value was not changed and stays on "100": 7 Seek_Error_Rate 0x000f 100 253 030 Pre-fail Always - 889878 Do I have a problem with this disk? preclear_start.txt preclear_finish.txt preclear_rpt.txt

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: Disk: /dev/sdc smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Copyright (C) 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net === START OF INFORMATION SECTION === Device Model: ST4000DM000-1F2168 Serial Number: Z300CRLF Firmware Version: CC52 User Capacity: 4,000,787,030,016 bytes Device is: Not in smartctl database [for details use: -P showall] ATA Version is: 8 ATA Standard is: ATA-8-ACS revision 4 Local Time is: Tue Apr 16 21:25:04 2013 CEST SMART support is: Available - device has SMART capability.
