Multi-Sector Transfers

This option automatically sets the number of sectors per block to the highest number supported by the
drive. This field can also be configured manually. Note that when this field is automatically configured,
the set value may not always be the fastest value for the drive. Refer to the documentation that came
with your hard drive to determine the optimal value and set it manually. NOTE: To make changes to
this field, the Type field must be set to User. The configuration options are: [Disabled] [2 Sectors] [4

LBA Mode Control

When Logical Block Addressing is enabled, 28-bit addressing of the hard drive is used without regard
for cylinders, heads, or sectors. Note that Logical Block Access may decrease the access speed of the
hard disk. However, LBA Mode is necessary for drives with greater than 504MB in storage capacity.
