Embodiment Construction

[0014] The method of the present invention is described in detail below with reference to the accompanying drawings.

[0015] The system structure of the present invention mainly includes a SATA male connector (for connecting the female connector of the motherboard), a SATA female connector (for connecting the SATA hard disk), a SATA Switch (switch) and a USB-to-SATA chip. Such as figure 1 As shown, when used as a second hard disk, the enable signal controls the SATA switch to turn off the SATA1 bus, so that SATA2 and SATA0 are connected; when used as a mobile hard disk, the switch turns off SATA2, so that SATA0 and SATA1 are connected, the role of the SATA Switch It is to control the three SATA signals to work independently without interfering with each other.

[0016] Combine below figure 2 To illustrate how this system works:

[0017] 1. When used as a second hard disk:

[0018] The ground pin on the SATA male head sends a SATA2_IN# signal (active low) to the EC (embed...

Abstract

The invention relates to a method for coupling a common SATA hard disk and a USB mobile hard disk. In the method, the common SATA hard disk and the USB mobile hard disk are coupled into an integer tobe used as a second hard disk of a computer so as to enlarge the storage capacity of a system, support a hot plug and be used as a mobile hard disk. The system comprises a power supply circuit, a signal switching circuit, a hot plug circuit and a USB-to-SATA conversion circuit, wherein when the power supply circuit is used as the second hard disk, an SATA interface supplies a power supply of 5V, and when the power supply circuit is used as the mobile hard disk, a USB interface supplies the power supply of 5V; the signal switching circuit judges whether an SATA function or a USB-to-SATA conversion function is used or not through a detection circuit and shuts down the non-operative circuit to prevent mutual signal interference; the hot plug circuit notifies the GPIO of a southbridge and supports the hot plug function of the second hard disk; and the USB-to-SATA conversion circuit realizes the functions of the USB mobile hard disk.

Description

technical field [0001] The invention relates to the technical field of computer hardware, in particular to a convenient storage system integrating the functions of a second hard disk and a mobile hard disk. technical background [0002] Information and information are constantly increasing, and computer hard drives have also grown from a few gigabytes before to hundreds of gigabytes, or even terabytes. The capacity of a single hard drive is already difficult to meet the needs of many users. Just play a few high-definition movies, MP3 will take up a lot of space. At present, many users of desktop computers are equipped with dual hard disk or multiple hard disk systems, and many first-line notebook manufacturers have also launched large-sized notebook computers equipped with dual hard disks. At the same time, convenient data copying and transfer are becoming increasingly important. For ordinary users, the built-in hard disk of the computer can be directly used as a mobile ha...
