Blk Mode

Option name:

Blk Mode

Possible values of an option:

[Auto], [On], [Off]

The option description:

Initially data interchange happened to a hard disk in "portions" on 512 byte, i.e. on sector for time. However, if to consider the sizes of the modern files, it is much more favourable to read out and write down given more large-size blocks. Switching-on of this option ([On]) leads to that is at a time transferred from 2 to 128 sectors (from 1 to 64 Kb), the optimal size of the unit is installed automatically, depending on drive characteristics.

Usage of a block mode of the data interchange supported by all modern drives, essentially raises high-speed performance of a disk subsystem, simultaneously reducing loading on the processor. The unique reason to refuse it ([Of]) — presence of rather "ancient" hard disk which is not supporting block date transmission.

Basically, problems can be watched and in old operating systems (we tell, Windows NT), but in practice all normally works normally. The only thing, on what it is necessary to pay attention, it that the size of the unit did not exceed the size of a cluster of file system.

If you are not assured, whether supports your drive a block mode of a data interchange or not, use value [Auto] — the necessary mode will be set automatically.
