Multiple hard drives can be installed, but only one hard drive can be used for system startup. The steps to install the hard drive are as follows:

1. Open the computer case and use screws to fix the new hard drive into the hard drive slot; plug in the power plug of the newly installed hard drive and use the SATA serial hard drive cable to connect the SATA interface of the hard drive. Connect to the SATA interface on the motherboard.

2. When you turn on the computer, you will find that there is only one partition. This is the default partition when you buy the hard disk. If you find it troublesome, you can use it directly. If you want to partition, right-click Computer, Manage, Disk Management. The following interface will appear. We can see that there is a disk called Disk One. Delete this partition.

3. Then select Add Volume, and an interface similar to the installation program will appear. Enter the size you want and start partitioning.

Extended information

SATA (Serial Advanced Technology Attachment) is an industry-standard serial hardware driver interface developed by Intel, IBM, Dell, APT, Maxtor and Seagate companies jointly proposed hard disk interface specifications.

In 2001, the Serial ATA Committee, composed of major manufacturers including Intel, APT, Dell, IBM, Seagate, and Maxtor, officially established the Serial ATA 1.0 specification. At the IDF Fall conference that year, Seagate announced The Serial ATA 1.0 standard was adopted and the establishment of the SATA specification was officially announced.

The SATA interface requires the support of hardware chips, such as Intel ICH5(R), VIA VT8237, nVIDIA's MCP RAID and SiS964. If the motherboard southbridge chip cannot directly support it, you need to choose a third-party chip. For example, Silicon Image 3112A chip, etc., but this will also produce some differences in hardware performance, and the driver is also relatively complicated.
