A while ago I tried to preclear 2 disks. One worked and something went wrong for the other so I had to start preclear again (don't remember the exact details though). I noticed now (several weeks later) in the logs the following after a startup : Dec 9 10:04:46 Tower preclear.disk: Resuming preclear of disk 'sdm' sdm was the disk that had issues with the preclear before but 'sdm' doesn't exist anymore now (there is no disk labeled sdm anymore). That disk is now sdk and is part of the cache pool. Seems preclear still thinks it has to do something. Is it possible/needed to stop this?

Seems to run fine on my 6.1.2 Very useful plugin! Thanks!

I've been reading a bit in this topic and found the following : http://lime-technology.com/forum/index.php?topic=4068.msg48756#msg48756 "The current "normalized" read error rate is 108, prior to the preclear, it was 117. The worst ever measured over the lifetime of the drive was "99" The failure threshold is "006" If the normalized read error rate goes BELOW "006" then the drive is considered to be failing. All drives have internal read errors. They are all designed to re-read on an error. As long as the normalized error rate is above the threshold, you are fine. Nobody except the manufacturer knows how to interpret the "raw" values in the right-most column (and they don't tell anybody)" So in case of my drive (post above) it would be : current normalized read error rate : 200 before : 200 Worst value ever : 200 Threshold : 051 Disk is perfectly fine at this moment. I should only worry if the current normalized value goes below 051. Raw value of 2 : just ignore it as we don't know what it means (only WD knows). Is this is a correct understanding?

Want to use a new 3Tb drive as my new Parity drive. Did 4 cycles of preclear on it. It seems ok except for the Raw_Read_Error_Rate which is at 2 while it was 0 at the start of preclear. Is this a concern? start : Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Vendor Specific SMART Attributes with Thresholds: Jan 25 06:50:31 Tower preclear_disk-diff[8717]: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 1 Raw_Read_Error_Rate 0x002f 200 200 051 Pre-fail Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 3 Spin_Up_Time 0x0027 100 253 021 Pre-fail Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 3 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 7 Seek_Error_Rate 0x002e 100 253 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 44 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 10 Spin_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 11 Calibration_Retry_Count 0x0032 100 253 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 3 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 1 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 1 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 194 Temperature_Celsius 0x0022 125 121 000 Old_age Always - 25 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 198 Offline_Uncorrectable 0x0030 100 253 000 Old_age Offline - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: 200 Multi_Zone_Error_Rate 0x0008 100 253 000 Old_age Offline - 0 end : Jan 25 06:50:31 Tower preclear_disk-diff[8717]: ============================================================================ Jan 25 06:50:31 Tower preclear_disk-diff[8717]: == Jan 25 06:50:31 Tower preclear_disk-diff[8717]: == S.M.A.R.T Final Report for /dev/sdi Jan 25 06:50:31 Tower preclear_disk-diff[8717]: == Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Disk: /dev/sdi Jan 25 06:50:31 Tower preclear_disk-diff[8717]: smartctl 5.40 2010-10-16 r3189 [i486-slackware-linux-gnu] (local build) Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Copyright © 2002-10 by Bruce Allen, http://smartmontools.sourceforge.net Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Jan 25 06:50:31 Tower preclear_disk-diff[8717]: === START OF INFORMATION SECTION === Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Device Model: WDC WD30EFRX-68AX9N0 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Serial Number: WD-WMC1T0071253 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Firmware Version: 80.00A80 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: User Capacity: 3,000,592,982,016 bytes Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Device is: Not in smartctl database [for details use: -P showall] Jan 25 06:50:31 Tower preclear_disk-diff[8717]: ATA Version is: 9 Jan 25 06:50:31 Tower preclear_disk-diff[8717]: ATA Standard is: Exact ATA specification draft version not indicated Jan 25 06:50:31 Tower preclear_disk-diff[8717]: Local Time is: Fri Jan 25 06:50:30 2013 CET Jan 25 06:50:31 Tower preclear_disk-diff[8717]: SMART support is: Available - device has SMART capability.
