This set of four options applies to four different partitioning schemes used in Windows and Linux.
You may want to disable processing for the schemes you do not need if there are bad sectors on the disk.
Disabling all four options leaves you with physical devices only, no partitions.
MBR (Master Boot Record) is the most widely used partitioning method, allowing primary and extended partitions, bootable or not,
on disks up to 2TB in size. In Windows Disk Management, disks using MBR are called "Basic Disk". One cannot make a RAID or spanned
volume on a disk using MBR.
LDM (Logical Disk Manager) is a Windows 2000/XP and higher component which
implements Dynamic Disks features, including striped, spanned, and
GPT (GUID Partition Table) is the successor to the MBR. It does not have a 2TB restriction and does not support spanned volumes or RAIDs.
md-raid is the Linux software RAID. If this option is active, ZAR can work with RAID0 and RAID5 arrays created by md-raid.
Because the search for md-raid superblocks can be very time-consuming, this option is disabled by default.
