Harddisk Paramaters
I tried to fiddle around with some HardDisk Drive utilities and got the following output from
Code:
smartctl -A /dev/sda1 Code:
=== START OF READ SMART DATA SECTION === My concern is the row that states Raw_Read_Error_Rate this figure seems too high... What exactly is it? If I see the ECC recovery, The number of unrecovered errors is 25837034... Is there something wrong? |
The RAW_VALUE numbers have little to do with actual errors that have occured. It is a six-bit number (with more info) that the VALUE (normalized number). The numbers to worry about are VALUE and THRESH. When VALUE gets close to THRESH, the drive is about to fail. I found this, which might ease your mind:

Thank you for the excellent explanation. I was wondering about the column
Code:
9 Power_On_Hours 0x0032 100 100 000 Old_age Always - 280 |
It's more likely that it 'started out as 100' which is normal, rather than 'reached 100 in 280 hours'.
If you check regularly, you will see also that the 'Hours of Operation' value wraps around too, so is not a practical indicator of the age of the drive, nor useful in trying to calculate its life expectancy. |
Thanks for this post - I was worried about this line
Code:
1 Raw_Read_Error_Rate 0x000f 068 056 006 Pre-fail Always - 105797684 Thanks - I Hope |
