palimpsest vs. smartctl

Wed Apr 15 08:22:45 UTC 2009

Since yesterdays rawhide update,  I am getting the 'One or more disks
are failing' icon in the notification area.

When I click on it, the palimpsest utility starts. It says that the
disk has bad sectors. When I click on details, I get
Ata Smart Attributes window, which claims that 'Reallocated Sector
Count' and 'Reallocation Count' fail.

I do not understand the data in the table very well, but what I found
surprising that the Value of Reallocated Sector Count is 0, what does
not seems to me like value which should fail.

I tried to check this with smartctl -a /dev/sda, I get  the output
that can be seen below and which looks quite without problem. Also
smartctl -l error, smartctl -l selftest report no errors.

My question is: Is my disk really failing or  is there some bug in the
reporting software?

Here is the smartctl -a /dev/sda output
