I'm not an expert on that, but the error log says: =3D=3D=3D START OF READ SMART DATA SECTION =3D=3D=3D SMART Error Log Version: 1 No Errors Logged The information of my HD is: SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 072 068 034 Pre-fail Always - 189802098 3 Spin_Up_Time 0x0003 070 070 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 099 099 020 Old_age Always - 1389 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 081 060 030 Pre-fail Always - 154801045 9 Power_On_Hours 0x0032 087 087 000 Old_age Always - 11801 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 099 099 020 Old_age Always - 1677 194 Temperature_Celsius 0x0022 047 051 000 Old_age Always - 47 195 Hardware_ECC_Recovered 0x001a 072 068 000 Old_age Always - 189802098 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0000 100 253 000 Old_age Offline - 0 202 TA_Increase_Count 0x0032 100 253 000 Old_age Always - 0 I hope you understand those values better than I do, and can take a conclus= ion. I never had a SuperBlock overwritten, and I deal with PC partitions since some years ago. I've only seen that after installing Plan9. I even didn't modify my grub before finding the SB error. I forgot looking at the partition information in Plan9 - now I can't, I will soon say something about that in this same thread.
