Of course. This is why we use unRAID at the first place : secure datas. So if nothing appears suspicious in this report, we can say that everything is fine with the disk an doesn't worry about the other values? Thank you

It's not coming harsh, I also apologize if mine sounded like I was complaining. Like I said, every answer is truly appreciated. The problem is that it is very difficult for a newbie not to drown as there is so many parameters to take care of while installing and running unRAID. Lots of them are greatly documented and as I said in my presentation post, even an average PC user can do it without much trouble providing he follows the steps and read as much as he can the main subjects. Preclear is one of the most important script and that's why I think it should be better documented, to avoid having every newbie coming her and asking for million-times-answered questions. As far as I read, it doesn't seem to be a lot of truly important lines to worry about in the preclear log, but it is very hard to find what's relevant in a 58 pages and very technical thread. For the "report" is this something like this ? : ============================================================================ No SMART attributes are FAILING_NOW 0 sectors were pending re-allocation before the start of the preclear. 0 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, the number of sectors pending re-allocation did not change. 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. ============================================================================

I read most of this subject but I probably missed useful things, sorry. This is very hard for newbies to have a clear view about all that happens in preclear, maybe if someone nice enough would do some kind of FAQ/WIKI/recap post about it, it would avoid seemingly stupid and redundant questions like mine (if anything clear and reachable had been written about it, I would undoubtly had read it). Something like : ... G-Sense_Error_Rate : Not to be taken care of Power-Off_Retract_Count : Check PSU if to many errors ... and so on I don't know anything about it but I guess it would not take hours to do and it would be an interesting knowledge database for very new users like me. The thing a bout the outdated preclear script is much more annoying to me cause I downloaded it not a week ago from what seemed to me the official preclear thread (this one : http://lime-technology.com/forum/index.php?topic=2817.0).

Damn the other disk seems to have errors too : SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 100 100 051 Pre-fail Always - 0 2 Throughput_Performance 0x0026 252 252 000 Old_age Always - 0 3 Spin_Up_Time 0x0023 067 067 025 Pre-fail Always - 10007 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 124 5 Reallocated_Sector_Ct 0x0033 252 252 010 Pre-fail Always - 0 7 Seek_Error_Rate 0x002e 252 252 051 Old_age Always - 0 8 Seek_Time_Performance 0x0024 252 252 015 Old_age Offline - 0 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 138 10 Spin_Retry_Count 0x0032 252 252 051 Old_age Always - 0 11 Calibration_Retry_Count 0x0032 252 252 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 90 181 Program_Fail_Cnt_Total 0x0022 100 100 000 Old_age Always - 1273 191 G-Sense_Error_Rate 0x0022 100 100 000 Old_age Always - 2 192 Power-Off_Retract_Count 0x0022 252 252 000 Old_age Always - 0 194 Temperature_Celsius 0x0002 064 059 000 Old_age Always - 30 (Lifetime Min/Max 19/41) 195 Hardware_ECC_Recovered 0x003a 100 100 000 Old_age Always - 0 196 Reallocated_Event_Count 0x0032 252 252 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 252 252 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0030 252 252 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0036 100 100 000 Old_age Always - 7 200 Multi_Zone_Error_Rate 0x002a 100 100 000 Old_age Always - 0 223 Load_Retry_Count 0x0032 252 252 000 Old_age Always - 0 225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always - 143 I find nowhere the explanations for this kind of errors, is this bad or can I add it anyway in my array?

Hello, I just precleared a drive before I add it to may array. I got errors and I don't know if it is bad or not : Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x002f 100 100 051 Pre-fail Always - 1 2 Throughput_Performance 0x0026 252 252 000 Old_age Always - 0 3 Spin_Up_Time 0x0023 068 067 025 Pre-fail Always - 9830 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 63 5 Reallocated_Sector_Ct 0x0033 252 252 010 Pre-fail Always - 0 7 Seek_Error_Rate 0x002e 252 252 051 Old_age Always - 0 8 Seek_Time_Performance 0x0024 252 252 015 Old_age Offline - 0 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 73 10 Spin_Retry_Count 0x0032 252 252 051 Old_age Always - 0 11 Calibration_Retry_Count 0x0032 252 252 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 59 181 Program_Fail_Cnt_Total 0x0022 100 100 000 Old_age Always - 1860 191 G-Sense_Error_Rate 0x0022 100 100 000 Old_age Always - 6 192 Power-Off_Retract_Count 0x0022 252 252 000 Old_age Always - 0 194 Temperature_Celsius 0x0002 064 064 000 Old_age Always - 29 (Lifetime Min/Max 19/33) 195 Hardware_ECC_Recovered 0x003a 100 100 000 Old_age Always - 0 196 Reallocated_Event_Count 0x0032 252 252 000 Old_age Always - 0 197 Current_Pending_Sector 0x0032 252 252 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0030 252 252 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0036 100 100 000 Old_age Always - 1 200 Multi_Zone_Error_Rate 0x002a 100 100 000 Old_age Always - 0 223 Load_Retry_Count 0x0032 252 252 000 Old_age Always - 0 225 Load_Cycle_Count 0x0032 100 100 000 Old_age Always - 78 The Raw_Read_Error_Rate and the UDMA_CRC_Error_Count kind of worry me but I'm not an expert at all and I want to be sure, so if someone can enlighten me it would me much appreciated. (I ran another preclear on this disk to see if ther is any more errors) Thank you!
