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:

=== START OF READ SMART DATA SECTION ===
SMART Error Log Version: 1
Warning: ATA error count 1248 inconsistent with error log pointer 5

ATA Error Count: 1248 (device log contains only the most recent five errors)
CR = Command Register [HEX]
FR = Features Register [HEX]
SC = Sector Count Register [HEX]
SN = Sector Number Register [HEX]
CL = Cylinder Low Register [HEX]
CH = Cylinder High Register [HEX]
DH = Device/Head Register [HEX]
DC = Device Command Register [HEX]
ER = Error register [HEX]
ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm SMART harddisk check logS.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
state.

After command completion occurred, registers were:
ER ST SC SN CL CH DH
