LBA (Logical Block Addressing) is a method of addressing data on a disk drive. In
the LBA mode, the maximum drive capacity is 137 GB. For drive capacities over
137 GB, your system must support 48-bit LBA mode addressing. If not, contact
your manufacturer or install an ATA/133 IDE controller card that supports 48-bit
LBA mode. The options are Disabled and Auto.
Block (Multi-Sector Transfer)
Block Mode boosts the IDE drive performance by increasing the amount of data
transferred. Only 512 bytes of data can be transferred per interrupt if Block Mode
is not used. Block Mode allows transfers of up to 64 KB per interrupt. Select
Disabled to allow data to be transferred from and to the device one sector at a
time. Select Auto to allow data transfer from and to the device occur multiple
sectors at a time if the device supports it. The options are Auto and Disabled.
