smartcheck results - my disk failing?

[ANewDay]

Using smartcheck config 5.32 for smartctl(5.33)
Checking /dev/sda....Ok
Checking /dev/sdb....
Errors:
Warning: ATA error count 1249 inconsistent with error log pointer 5

ATA Error Count: 1249 (device log contains only the most recent five errors)
Error 1249 occurred at disk power-on lifetime: 13073 hours (544 days + 17 hours)
Error 1248 occurred at disk power-on lifetime: 7960 hours (331 days + 16 hours)
Error 1247 occurred at disk power-on lifetime: 7960 hours (331 days + 16 hours)
Error 1246 occurred at disk power-on lifetime: 7960 hours (331 days + 16 hours)
Error 1245 occurred at disk power-on lifetime: 7960 hours (331 days + 16 hours)

now I read that error is false positive but it shows 1249 of them should I be worried?
