What is the relationship between LBA value and hard disk size?

The relationship between LBA of factory and GB is GB *1000 *1000 *1000/512 = LBA, and the relationship between LBA of individual and GB is GB *1024 *1. The seventh place of LBA is G, for example, 7,000,000 LBA is about 3.5GB, so you need to start with 50GB and scan in100,000,000 LBA.

Knowledge expansion:

The capacity of hard disk is in MB and GB. The early hard disk capacity was low, mostly in MB. 1September, 956, the world's first disk storage system made by IBM was only 5MB. Nowadays, with the rapid development of hard disk technology, hundreds of GB hard disks have entered the hands of home users.

After buying a hard disk, careful people will find that the capacity of the hard disk in the operating system does not match the official nominal capacity, which is less than the nominal capacity. The greater the capacity, the greater the difference. The nominal 40GB hard disk shows only 38G in the operating system. This is not because manufacturers or distributors cheat consumers by shoddy products, but because hard disk manufacturers have different calculation methods for capacity and unit conversion relationships with operating systems.

In terms of computing power, disk manufacturers take every 1000 as a decimal, every 1000 bytes, every 1000KB, every 1000MB, every 1000GB and every 1000 GB.
