Yes, though it varies by particular disks. smartctl -a /dev/whatever produces SMART data which may include things like: 233 Media_Wearout_Indicator 0x0032 002 002 000 Old_age Always - 0 or 241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 7395041209 or 177 Wear_Leveling_Count 0x0013 099 099 000 Pre-fail Always - 4 Each of which tells you relevant things without being perfect predictors. -dsr-
