Normal for longer responding blocks at beginning of HDD?

As the title asks, it is it common for the blocks that take >500ms and less to be more readily found at the beginning of a hard drive? Usually when I run a HDD check, it seems like half of the longer reacting blocks are at the beginning, and also when I format drives with some programs, they like to start the format around 7mb after the beginning sectors - Not sure if this is just a coincidence or?

As example, I just bought a drive from ebay and I ran the hdd checker, and one block was >500ms (literally the fourth block), and 2 of the 4 only <50ms blocks are just a few rows down.

Also another question, the same test finished with 37 blocks that were <500ms but I am not exactly sure where those are, but if it is possible to relocate these. Or do you think it would not make a difference (This will later become my OS and a storage medium drive).

Programs like Puran Defrag, Iobit Smart Defrag, will move the data, i.e. "optimize" it. But, the actual blocks themselevs on the hard drive cannot be moved.

I know what your saying and thanks for the response. But I would still like to know if their is any correlations with slow sectors at the beginning of a drive.

The beginning of the drive should be faster as the head doesn't have to move far from the resting position. If there are spots taking >250ms, that sounds like it has reallocated bad sectors and has to seek to the end of the drive to read them. Check your SMART data for the reallocated sector count.

I would also run chkdsk/r, to see if that helps any.
