January 21, 201610 yr I'm about to upgrade a drive to increase storage capacity (replacing a 2tb drive with a 4tb drive). Other then age are there particular SMART stats I could be using to give me an indication as to which drive I should replace? I've attached the four SMART reports. Thanks in advance. rs-smart-20160121-0837-drive4.zip rs-smart-20160121-0837-drive5.zip rs-smart-20160121-0838-drive6.zip rs-smart-20160121-0838-drive7.zip
January 21, 201610 yr Community Expert Device Model: ST32000542AS Serial Number: 5XW2JPP2 199 UDMA_CRC_Error_Count 0x003e 200 017 000 Old_age Always - 2607 Disk looks healthy, if this value keeps incresing replace sata cable. Device Model: ST32000542AS Serial Number: 6XW1ZW7Z 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 38 187 Reported_Uncorrect 0x0032 087 087 000 Old_age Always - 13 Should be ok, but according to blackblaze has a much higher probability of failure, would do extended SMART test and keep an eye on these values. Device Model: ST2000DL003-9VT166 Serial Number: 6YD1R23A 183 Runtime_Bad_Block 0x0032 001 001 000 Old_age Always - 945 184 End-to-End_Error 0x0032 092 092 099 Old_age Always FAILING_NOW 8 SMART failing, replace this one first. Device Model: ST32000542AS Serial Number: 5XW2HQ53 5 Reallocated_Sector_Ct 0x0033 096 096 036 Pre-fail Always - 183 183 Runtime_Bad_Block 0x0032 002 002 000 Old_age Always - 98 199 UDMA_CRC_Error_Count 0x003e 200 164 000 Old_age Always - 8750 Can be ok but does not look very healthy, would do extended SMART test and if it passes keep an eye on these values, monitor UDMA_CRC for bad sata cable. From the 4, only the 1st looks completely healthy, I would replace the other 3, that does not mean that they are about to fail, and can last years, it’s difficult to predict.
