1 Does a 40GB motherboard support a large 120GB hard drive?

The landlord means the CPU, right?

There should be no problem with such a motherboard.

If your host supports 80g hard drives.

It can support 120G.

The bayonet of the hard disk limit is 74g a 137g one.

The landlord borrowed an 80 square to go up.

Just take a look.

In addition, the following information is added.

Earlier motherboards mostly used 28-bit LBA hard disk addressing, and the LBA method refers to the use of hard disks in the form of logical blocks, where the size of each logical block is 512 bytes. Therefore, under the 28-bit LBA hard disk addressing mode, the theoretical limit of the number of logical blocks is 2 to the 28th power, that is, 268435456 blocks, and each block is multiplied by 512 bytes, then the theoretical capacity limit of the hard disk is: 268435456 (block) * 512 (bytes) = 137,438,953,472 bytes = 137GB.

Of course, this is also due to the fact that the size of the hard disk used by people in the past is usually smaller, and the development of the motherboard lags behind the development of the hard disk, and then when the hard disk has exceeded the size of 137GB, the motherboard production rules are still in the era of using 28bit LBA hard disk addressing, so the 137GB capacity limit is coming! Obviously, for hard disk manufacturers, the solution to this 137G capacity limit is actually very simple, as long as you use a higher number of hard disk addressing bits. At present, all IDE ATA hard drives with a capacity of more than 137G use 48-bit LBA addressing, and the theoretical capacity limit of 48-bit LBA addressing is 144,115,188,075,855,872 bytes = 144,000,000 GB!

Obviously, for many years to come, this capacity limit will definitely be enough! If your motherboard BIOS reports exactly 137GB of capacity in the boot test, then you can assume that your system does not support 48-bit LBA hard drive addressing. However, if you don't currently use a hard drive with more than 137GB, how can you tell if your motherboard supports 48-bit LBA addressing?

The easiest way is to use Intel's 48-bit LBA test program to test your motherboard.

No, and it is generally not possible to flash the BIOS to support it. Your motherboard may not be able to install the adapter card yet.

Changing motherboards may be the only option.

Not supported. It can be supported by flashing the BIOS firmware. Or install an array card.!

You'll find out if you try it!

If it doesn't work, jump the hard disk to only 40g

1TB should be a mechanical hard disk, **low, slow to store and read data, mainly used to store data;

120GB should be dedicated to the SSD, ** high, the memory reading is fast, mainly used to install the system;

Advantages: SSDs are faster than HDDs in terms of computer power on/off, large application loading, and data transfer. And in the heat, noise, seismic ability is strong;

Disadvantages: After the data on the SSD is deleted, it cannot be recovered with the help of software such as data recovery; SSDs have a limit on the number of writes.
