[smartmontools-support] Disk failure notification options

Hi Alex

If I recall, the raw_read_error_rate was less than a few hundred about

raw_read_error_rate MAY indicate a failing drive, but doesn't have to.

You may also take a look at check_smart.pl, which uses smartctl in the
background, for drive monitoring.
As raw_read_error_rate is not part of the default raw attribute list to be
checked, you can expand this:

./check_smart.pl -d /dev/sdc -i ata -r 'Current_Pending_Sector,
Reallocated_Sector_Ct, Program_Fail_Cnt_Total, Uncorrectable_Error_Cnt,
Offline_Uncorrectable, Runtime_Bad_Block, Reported_Uncorrect,
Reallocated_Event_Count, Command_Timeout,Raw_Read_Error_Rate' -w
'Raw_Read_Error_Rate=1947'

This will alert you when Raw_Read_Error_Rate increased (+1 in your case) or
if all other attributes from the raw list (-r) have a non-zero value.
