Today I noticed that in one SATA HD that I'm monitoring has the "Current_Pending_Sector" with RAW_VALUE=1 when inspecting the SMART attributes with smartmontools. Here is the output from smartctl.exe
SMART Attributes Data Structure revision number: 16
Vendor Specific SMART Attributes with Thresholds:

Considering that this is a Windows 2008 server, what is the best way to deal with this problem?
Now the following message appeared in EventLog:
smartd
2360
CRIT
Device: C:, 2 Currently unreadable (pending) sectors (changed +1)
Device: C:, ATA error count increased from 1 to 5
It appears that the drive is slowly deteriorating, I think it's best to replace it.
