Thanks, I looked at a tutorial at

http://smartmontools.sourceforge.net/badblockhowto.html

question is related to this statement

In this example, the disk is failing self-tests at Logical Block
Address LBA = 0x016561e9 = 23421417. The LBA counts sectors in units
of 512 bytes, and starts at zero.

How to convert LBA = 0x016561e9 to 23421417?
