Does it mean that it is firmware on the drive that decides how looks logical disk structure ?

All modern drives are LBA and have been LBA for a very long time. If a drive is a gig or more in size you can safely say it supports LBA.

LBA means the number of heads, tracks, and sectors a drive has -- physical or logical -- are wholly irrelevant now. Ask the drive for sector 0, it gives you sector 0. Ask for sector 99,999,999 and it gives you sector 99,999,999. Ask for sector 16,384 and it gives you sector 16,384. The "structure", if you can call it that, is a straight line from start to finish. The translation between these linear numbers and head, track, sector positioning is all done internally by the drive's microcontrollers and their programming(yes, their firmware.)
