Linux has nothing that compares to 'modify' directly, it has 'rwx' or
'read, write and enter/execute', for what you want, you need to use
Windows ACL's and these will be stored in an EA.

Posting parts of a smb.conf without the [global] section is like
posting just one page of a book, you do not get the full context ;-)

The above two lines are interesting, if something is writable, this
means it isn't just readable, or to put it another way, they both mean
the same so why have both ?

Why don't you want oplocks ?

To be honest, I would replace all of the above with this:

[pripomienkovanie]
    path = /mnt/data_disk/www/pripomienkovanie/
    read only = no

Then follow the wikipage I point you to earlier.
