Uh, 79725167 - 63 = 79725104 and 79725104 - 39845888 = 39879216. How
did you arrive at 39879105?
I am sorry, it was my confusion.
My calculation was for *LBA=79725056* reported in messages:
ad4: FAILURE - READ_DMA status=51<READY,DSC,ERROR> error=40<UNCORRECTABLE>
LBA=79725056
off-by-111...
Are you sure 'smartctl -l error' reports only one error?
There is really only one error. The example from my e-mail is half a
year old, but the disk is running fine from this time. The error occured
at the initial gmirror sync. No more errors shown after rewriting the
disk with zeros.
As you can see, there are really two different numbers
LBA=79725056 in messages and LBA = 0x04c0826f = 79725167 in SMART log.

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 1 occurred at disk power-on lifetime: 0 hours (0 days + 0 hours)
When the command that caused the error occurred, the device was
active or idle.
After command completion occurred, registers were:
