Some older motherboards can not support large-capacity hard drive, in fact, this is so-called “hard disk capacity limitation.” Here, we analyze the causes of capacity constraints.
(1)What’s capacity constraints
The former engineer in order to save and make magnetic storage products easy to implement when designing,such as use fewer addressable range, and this laid a huge hidden dangers to the current hard disk capacity constraints. Capacity constraints has a well-known “8.4GB capacity barrier” problem, because the low version BIOS use 10 bits to represent the number of cylinders, using 8 bits to represent the number of heads, with 6 to represent the number of sectors, thus the maximum capacity of the BIOS to support is only 512 × 63 × 255 × 1024 = 8.4GB, so some users will come across large-capacity hard disk capacity problems when replaced large-capacity hard drive after used this BIOS system.
(2) Breakthrough capacity constraints
Following the above analysis, for the “old motherboard can not recognize large-capacity hard drive”, the direct method is to update the BIOS.
In addition to update motherboard BIOS, users can also use some of the hard disk management tools to solve the problem, these tools can be foundin the official website of the hard disk manufacturer. Users can choose corresponding hard disk management tools, such as Data Lifeguard (Data LifeGuard) package of the EZ-Install (EZmaker.exe) provided by Western Digital will be able to play a certain role. According to the software readme file states: “When the user’s system does not support large-capacity hard disk, you can use EZ-Install program to partition and format a large capacity hard drives of Western Digital.”
