Where can I find a key fo reading all the other exciting numbers listed under the banner ``SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds:'' ? On the hard-drive I use for my backups, a SAMSUNG HD501LJ, all the numbers I read looks fine to me, but I want to be sure. Thus it would be nice have a key for the table that `smartctl -a /dev/ad6' outputs. My two other drives, I use to store my OS and my data, are MAXTOR STM3250820AS (I do not have a RAID setup, it just happens that I have twin hard drives). They both have `Reallocated_Sector_Ct=0' but have positive `Raw_Read_Error_Rate', `Seek_Error_Rate'. Additionally, the faulty drive has positive `Reported_incorrect=119',`Current_Pending_Sector=4294967295' and `Offline_Uncorrectable=4294967295'. As looking for hints on google leads to many threads discussing hard-drive failures, I did not find what a pleasant description of the signification of these numbers. -- Kind regards, Michaël
