I'm seeing this in logwatch every morning. Does it indicate sdb is in trouble?
/dev/sdb : Prefailure: Raw_Read_Error_Rate (1) changed to 53, 69, 65, 62, 60, 59, 58, 57, 56, 55, 54, 55, 54, 67, 63, 61, 60, 48, 49, 48, 49, 50, 49, 50, 73, 63, 60, 57, 56, 55, 54, Usage: Hardware_ECC_Recovered (195) changed to 56, 55, 56, 57, 56, 55, 56, 55, 54, 55, 53, 54, 55, 54, 56, 55, 54, 55, 56, 55, 56, 57, 55, 56, 55, Usage: Temperature_Celsius (194) changed to 34, 35, 34, 34,

Well, the temperature does not really give you a warning of anything except temperature changes (as you might have already guessed). Next is hardware ECC recovery. Some harddrive manufacturers give the 195 a different meaning, so its best to find the harddrive manufacturer, and find out what exactly 195 stands for. I have a disk that gives me this hardware ECC stuff all the time, but there's nothing really wrong with it. The numbers you are getting here are similar to what I'm getting on my machine, but just to be sure, find out what 195 really means for your HD.
On to raw_read_error_rate. These errors, as the prefix already suggests, occur when the harddrive is about to fail (prefailure). The numbers you are getting are not indicating any real problem, but if they increase towards the 100's or 1000's, you do have something to worry about.
So in short: nope, not a real problem, but keep a close eye on the raw_read_error_rate.
