SMART harddisk check log
I get an email from smartmontools regarding my secondary (backup) drive. It doesn't look good, anyone got this similar problem before? I don't know what to do next, just hoping that this is a fluke in the program. here's the email:

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm
S.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 1248 occurred at disk power-on lifetime: 7960 hours (331 days + 16 hours)
When the command that caused the error occurred, the device was in an unknown
