January 5, 201610 yr Question for you guys. This disk in question passed Pre Clear but afterwards it still shows offline uncorrectable at a value of 314. I found that strange based on what the pre clear information. Should I just toss the disk? I honestly figured filling it with zeros would do the trick but apparently not. ================================================================== 1.15 = unRAID server Pre-Clear disk /dev/sdb = cycle 1 of 1, partition start on sector 64 = Disk Pre-Clear-Read completed DONE = Step 1 of 10 - Copying zeros to first 2048k bytes DONE = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward. DONE = Step 4 of 10 - Clearing MBR bytes for partition 2,3 & 4 DONE = Step 5 of 10 - Clearing MBR code area DONE = Step 6 of 10 - Setting MBR signature bytes DONE = Step 7 of 10 - Setting partition 1 to precleared state DONE = Step 8 of 10 - Notifying kernel we changed the partitioning DONE = Step 9 of 10 - Creating the /dev/disk/by* entries DONE = Step 10 of 10 - Verifying if the MBR is cleared. DONE = Disk Post-Clear-Read completed DONE Disk Temperature: 26C, Elapsed Time: 27:52:22 ========================================================================1.15 == WDCWD2003FYPS-27W9B0 WD-WCAVY4447100 == Disk /dev/sdb has been successfully precleared == with a starting sector of 64 ============================================================================ ** Changed attributes in files: /tmp/smart_start_sdb /tmp/smart_finish_sdb ATTRIBUTE NEW_VAL OLD_VAL FAILURE_THRESHOLD STATUS RAW_VALUE Seek_Error_Rate = 100 200 0 ok 0 No SMART attributes are FAILING_NOW 314 sectors were pending re-allocation before the start of the preclear. 313 sectors were pending re-allocation after pre-read in cycle 1 of 1. 0 sectors were pending re-allocation after zero of disk in cycle 1 of 1. 0 sectors are pending re-allocation at the end of the preclear, a change of -314 in the number of sectors pending re-allocation. 0 sectors had been re-allocated before the start of the preclear. 0 sectors are re-allocated at the end of the preclear, the number of sectors re-allocated did not change. root@NAS002:/usr/local/emhttp# So after that, unRAID still shows a yellow warning with offline uncorrectable sitting back at 314. Also shows a multi zone error rate of 104. So again, just thought with numbers that high it wouldn't have passed the pre clear. Your thoughts?
