My OS is configured to use <smartd|smartctl> to check the health of both of my hard-drives; one drive(/dev/hdb) is mounted and used routinely. The second drive (/dev/hda) once had a problem - which has been rectified by reformatting. It is now only mounted when being used for storing backups.
However, "smartd" dutifully checks its health every 30 minutes and reports the presence of an unreadable HD sector - despite the fact that this is no longer the case.
Full details are below.
1. smartd checks:
Sep 24 08:16:41 carrot smartd[2717]: Device: /dev/hda, 41 Currently unreadable (pending) sectors
Sep 24 08:16:41 carrot smartd[2717]: Device: /dev/hda, 41 Offline uncorrectable sectors
Sep 24 08:46:40 carrot smartd[2717]: Device: /dev/hda, 41 Currently unreadable (pending) sectors
Sep 24 08:46:40 carrot smartd[2717]: Device: /dev/hda, 41 Offline uncorrectable sectors
2. smartctl test:
[root@carrot felixk]# smartctl -H /dev/hda

While the problem is just an irritation, any advice on how to get rid of the misleading messages will be gratefully received.
