4096 Cylinder Truncation

Synonym for the: 4096 Cylinder Limitation. On some older BIOS', primarily those that auto-configure the disk drive, a hang may occur when the drive cylinder value exceeds 4096. The 4096 Cylinder Limitation jumper reduces the capacity in the Identify Drive to 4096, allowing large capacity drives to work with older BIOS'.

A BIOS upgrade, BIOS extension or software driver is sometimes required to access the full capacity of the drive. This is an example of just one type of Capacity Barrier.
