If your hard disk supports the block mode, select Auto for the automatic determination of the number of the blocks per
request. Several sectors can be at the same time read/written. The data transfer rate will be increased.
Available settings are: Auto and Disabled.
Auto
The data transfer from and to the device occurs multiple sectors at a time if the device supports it. Block
mode allows transfers of up to 64Kb per interrupt.
Disabled
The data transfer from and to the device occurs one sector at a time. Only 512 byte of data can be
transferred per interrupt if block mode is not used.
This setting should be used only if read and write failures occur with "Auto".
