[smartmontools-support] smartd error unreadable sectors - but seatools long test passes

[Sebastian N. <seb...@ar...>]

Hi everyone

in my syslogs I have following error:
Device: /dev/sdb, 4 Currently unreadable (pending) sectors
Device: /dev/sdb, 4 Offline uncorrectable sectors
these messages repeat every 30 minutes

/dev/sdb is a seagate baracuda disk.

/dev/sdb is part of a linux software raid1, so it was possible to extract the
disk and check it in another machine using seatools dos cd (as FAQ said) without
rebooting the computer.

But seatools did not find any errors (tried short and long test which should
repair bad sectors)! I inserted the disk again and still get the errors from
smartd in syslog.

Why does smartd repeat the message? I guess it always means the same 4 sectors.
Does it save the status of the disk and just repeats the old message? Can I tell
smartd that the disk is checked?

Is there any other way to get rid of the problem.

Thanks for your help
Sebastian
