Pozrel som na tie smart hodnoty a vidim toto: Device Model: M4-CT128M4SSD1 Firmware Version: 040H 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 100 100 050 Pre-fail Always - 0 5 Reallocated_Sector_Ct 0x0033 100 100 010 Pre-fail Always - 0 9 Power_On_Hours 0x0032 100 100 001 Old_age Always - 16880 12 Power_Cycle_Count 0x0032 100 100 001 Old_age Always - 39 170 Grown_Failing_Block_Ct 0x0033 100 100 010 Pre-fail Always - 0 171 Program_Fail_Count 0x0032 100 100 001 Old_age Always - 0 172 Erase_Fail_Count 0x0032 100 100 001 Old_age Always - 0 173 Wear_Leveling_Count 0x0033 181 181 010 Pre-fail Always - 5277 174 Unexpect_Power_Loss_Ct 0x0032 100 100 001 Old_age Always - 35 181 Non4k_Aligned_Access 0x0022 100 100 001 Old_age Always - 3 0 3 183 SATA_Iface_Downshift 0x0032 100 100 001 Old_age Always - 0 184 End-to-End_Error 0x0033 100 100 050 Pre-fail Always - 0 187 Reported_Uncorrect 0x0032 100 100 001 Old_age Always - 0 188 Command_Timeout 0x0032 100 100 001 Old_age Always - 0 189 Factory_Bad_Block_Ct 0x000e 100 100 001 Old_age Always - 86 194 Temperature_Celsius 0x0022 100 100 000 Old_age Always - 0 195 Hardware_ECC_Recovered 0x003a 100 100 001 Old_age Always - 0 196 Reallocated_Event_Count 0x0032 100 100 001 Old_age Always - 0 197 Current_Pending_Sector 0x0032 100 100 001 Old_age Always - 0 198 Offline_Uncorrectable 0x0030 100 100 001 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x0032 100 100 001 Old_age Always - 0 202 Perc_Rated_Life_Used 0x0018 181 181 001 Old_age Offline - 175 206 Write_Error_Rate 0x000e 100 100 001 Old_age Always - 0 Nie som si isty, ale citam to spravne, ze disk je “po svojej zivnostnosti” na 175% (Perc_Rated_Life_Used)? A Wear_Leveling_Count 5277 je asi tiez velmi vysoka hodnota, ze? Druhy disk ma podobne hodnoty. Zaver je teda, ze je potreba vymenit disk?
