Two days ago I installed a brand new SSDNow E50 series (Enterprise) disk on a server. I intend to move the OS there. I just did the physical install and copied a few files to and from it just to see if it was OK. I left it there, waiting for an opportunity to configure it to do real work. Now I have looked at it with smartctl -a and it gives me the following info: 1 Raw_Read_Error_Rate 0x0033 104 104 050 Pre-fail Always - 9127078 5 Reallocated_Sector_Ct 0x0033 100 100 003 Pre-fail Always - 0 9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 55 (241 12 0) 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 7 13 Read_Soft_Error_Rate 0x0032 104 104 000 Old_age Always - 9127078 100 Unknown_Attribute 0x0032 000 000 000 Old_age Always - 4 170 Unknown_Attribute 0x0032 000 000 000 Old_age Always - 8480 171 Unknown_Attribute 0x000a 100 100 000 Old_age Always - 0 172 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 0 174 Unknown_Attribute 0x0030 000 000 000 Old_age Offline - 6 177 Wear_Leveling_Count 0x0000 000 000 000 Old_age Offline - 0 181 Program_Fail_Cnt_Total 0x000a 100 100 000 Old_age Always - 0 182 Erase_Fail_Count_Total 0x0032 100 100 000 Old_age Always - 0 184 End-to-End_Error 0x0032 100 100 090 Old_age Always - 0 187 Reported_Uncorrect 0x0012 100 100 000 Old_age Always - 0 194 Temperature_Celsius 0x0022 028 033 000 Old_age Always - 28 (Min/Max 20/33) 195 Hardware_ECC_Recovered 0x001c 120 120 000 Old_age Offline - 9127078 196 Reallocated_Event_Count 0x0033 100 100 003 Pre-fail Always - 0 198 Offline_Uncorrectable 0x0010 120 120 000 Old_age Offline - 75479755259904 199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0 201 Unknown_SSD_Attribute 0x001c 120 120 000 Old_age Offline - 9127078 204 Soft_ECC_Correction 0x001c 120 120 000 Old_age Offline - 9127078 230 Unknown_SSD_Attribute 0x0013 100 100 000 Pre-fail Always - 0 231 Temperature_Celsius 0x0000 100 100 011 Old_age Offline - 0 232 Available_Reservd_Space 0x0032 000 000 000 Old_age Always - 33 233 Media_Wearout_Indicator 0x0032 000 000 000 Old_age Always - 6 234 Unknown_Attribute 0x0032 000 000 000 Old_age Always - 7 235 Unknown_Attribute 0x0033 100 100 002 Pre-fail Always - 0 241 Total_LBAs_Written 0x0032 000 000 000 Old_age Always - 7 242 Total_LBAs_Read 0x0032 000 000 000 Old_age Always - 5 Just look at the number under "198 Offline_Uncorrectable". Is this normal for this type of disk? Is smartctl misinterpreting the disk's features? The disk has been there essentially doing nothing and it presents such enormous numbers of errors. Why? This is under CentOS 7 (1511).

Is this normal for this type of disk? Is smartctl misinterpreting the disk's features? The disk has been there essentially doing nothing and it presents such enormous numbers of errors. Why?That raw parameter is holding something other than a raw count, and smartctl doesn't know how to interpret the high-order bits. 75479755259904 = 0x44a600000000 -- Bob Nichols "NOSPAM" is really part of my email address.
