My Book Live - System S.M.A.R.T Status

All,

The other day I performed a SMART check on my 1TB My Book Live. Altough my MBL passed its SMART short test, I decided I wanted to have a look at the log, and I need to help to understand the values of the corresponding SMART Attribute Values:

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 200 200 051 Pre-fail Always - 0
3 Spin_Up_Time 0x0027 245 164 021 Pre-fail Always - 2708
4 Start_Stop_Count 0x0032 097 097 000 Old_age Always - 3402
5 Reallocated_Sector_Ct 0x0033 200 200 140 Pre-fail Always - 0
7 Seek_Error_Rate 0x002e 200 200 000 Old_age Always - 0

194 Temperature_Celsius 0x0022 104 084 000 Old_age Always - 46
196 Reallocated_Event_Count 0x0032 200 200 000 Old_age Always - 0
197 Current_Pending_Sector 0x0032 200 200 000 Old_age Always - 0
198 Offline_Uncorrectable 0x0030 200 200 000 Old_age Offline - 0
199 UDMA_CRC_Error_Count 0x0032 200 200 000 Old_age Always - 0
200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 0

Should I be worried be with these values and look at replacing it, Ive had it over a year and do use it quite a bit.

Thanks
