Unlike physical geometry which are the actual heads, tracks, and sectors, logical geometry is basically that information which is reported as addressable to the Bios/Os
They are both life and logic theory.
When you partition a hard drive into two or more partitions (storage areas) those extra drives are called logical drives. So you can have 2 or 3 or more logical drives on one physical hard drive. It varies.
One of your drives has an error (known or unknown)
* use and allocate disk space more efficiently and flexibly * move logical volumes between different physical devices * have very large logical volumes span a number of physical devices * take snapshots of whole filesystems easily, allowing on-line backup of those filesystems * replace on-line drives without interruanpting services
As a rule, the most common RAID levels in use today are:No RAID - logical data volumes exist within single physical driveRAID 0 - logical data volumes striped across multiple physical drives with no parity/data protection. Common, but not necessarily a good idea (backup is important here).RAID 1 - logical data volumes mirrored, bit-for-bit, between two physical drives (in come implementations, additional mirror drives can be created)RAID 5 - logical data volumes striped across multiple drives with parity/data protection generated and distributed among all drives in the RAID set.Three notes come to mind:Depending on implementation, RAID devices appear as a logical (or physical) drive to the OS or application. Software RAID, configurable in utilities such as in Windows Disk Manager or MDADM (Linux) works just below the operating system, providing a representation of a virtual physical disk to the operating system.Sometimes, RAID levels are combined, such as RAID 0+1 (striped, then mirrored) or RAID 1+0/10 (mirrored, then striped).As drives and RAID sets get larger (2-3 TB+), the time to recalculate/recover data for a failed physical drive becomes prohibitive, both in downtime/degraded operation and vulnerability to data loss from an additional failure.A number of new technologies, as well modifications to classic RAID, are being explored to address shortcoming 3.
There are three types of partitions: primary partitions, extended partitions and logical drives
The computer management feature in Windows can be used to partition a drive and create logical drives within these partitions. There are also commercial and non-commercial programs available for the same purpose.
It probably has a partition, which is a way of separating a physical drive into 2 or more logical drives. This is useful is you want to install 2 operating systems, or if you want your operating system on one drive and your data on the other.
With FDISK you can create or delete harddisk partions or logical drives

It may be due to bad sectors that cannot be repaired, or depending on the format partition type FAT16, FAT32, or NTFS. It may be you have the physical HD partitioned into logical drives.
