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

79725056 - 63 - 39845888 = *39879105*

Your calculation is for LBA reported by SMART log

   40 51 00 6f 82 c0 44  Error: UNC at LBA = 0x04c0826f = *79725167*

That's why I get different result ;) I must pay more attention to the 
numbers next time!

It is interesting that there are two different LBAs for "same" error 
(appeared at the same time)
