No, lifetime hours is the powered on hours since it was factory reset (so
you'll normally buy one of these at 0, and it'll grow as you use it).  These
were the errors (snipped):

Error 4 occurred at disk power-on lifetime: 5383 hours (224 days + 7 hours)
Error 3 occurred at disk power-on lifetime: 5383 hours (224 days + 7 hours)
Error 2 occurred at disk power-on lifetime: 5383 hours (224 days + 7 hours)
Error 1 occurred at disk power-on lifetime: 5383 hours (224 days + 7 hours)

So these are all ~2500 hours ago (since now we're at >7903), so still a very
big number.

These are the self tests you've run (which are all fine):

I'd interpret this as mild error, fixed and logged, that's your lot.  The only
time I've had truly knackered disks they've been picked up by the self test,
but the other figures give you a warning that a failure is more likely.

No problem.
