Re: Disk failure



Hello,



Try looking how many Current Pending Sectors and how many Reallocated Sectors there are.

If there are only a few sectors (like 1 or 2), you may force the Current Pending sectors to be rewritten by following instructions here:

http://www.smartmontools.org/browser/trunk/www/badblockhowto.xml <http://www.smartmontools.org/browser/trunk/www/badblockhowto.xml> 



In your case (assuming your drive is /dev/sda):



dd if=/dev/sda of=/tmp/673565131.sector bs=4096 count=1 seek=$((673565131 / 8)

dd if=/dev/zero of=/dev/sda bs=4096 count=1 seek=$((673565131 /8)

dd if=/tmp/673565131.sector of=/dev/sda bs=4096 count=1 seek=$((673565131 /8)



Then you can keep an eye on the disk by having smartd check it regulary.

If there are more sectors than 10, in my experience, you should change the drive as more and more bad sectors will appear.



Regards,

Ozy.

BTW, did a new smartctl -a on the device and got this lines:


SMART Self-test log structure revision number 1
Num  Test_Description    Status                  Remaining  LifeTime(hours)  LBA_of_first_error
# 1  Short offline       Completed: read failure       90%      5529         673565131
