Advanced

disable the maximum boot size for a logical drive. The default boot size is 32 sectors
(16 kbytes) per track, and the maximum boot size is 63 sectors per track.

Some operating systems need to use the maximum boot size to be able to create large
boot partitions. For example, enabling the maximum boot size on a logical drive in

a maximum size of 8 GB.
NOTE:
Enabling the maximum boot size may decrease performance of the logical drive.
