How to install a dual hard drive

Now because the data is more and more large, so that our hard disk memory is not enough, so we need to add a hard disk, to increase the capacity of memory. Dual hard disk configuration is not so simple, it has a lot of attention to the place, such as power problems, as well as the main hard disk, from the disk of the points. The details of installing a dual hard drive are described below.

　A reasonable configuration of the hard disk jumper

Before installing two hard drives, you should first determine whether there is a second hard drive in the chassis, if only the position of 5 inch slots, you need to prepare a fixed frame. Also determine if the power supply power is sufficient. When installing two hard drives on a single line, you should set the two hard disks to be the main and from the disks as you wish, so that you can use them after installation. The main, from disk settings can be done in the following two ways.

1, by the hard disk jumper set

All IDE devices, including hard disks, use a set of jumpers to determine the main, from-state after installation. Most of the hard disk jumpers are set between the power connection seat and the data cable connection socket, usually consisting of 3 groups (6 or 7) or 4 group (8 or 9) pins plus one or two jumper caps. In addition, the front or back of the hard disk must also be printed with the main disk, from the disk and the cable selected by the jumper method.

Various types of hard disk jumper methods and markings are similar, for example, the jumper of the hard disk is usually 9-pin 4 groups, one of which is called "Key" for positioning so that users correctly identify the jumper location.

2, by the hard disk jumper and 40-core special hard drive line with the determination

This master, from disk setting is to first set the hard disk jumper after "cable selection is valid", and then the main, from the disk to connect to the corresponding hard drive cable plug. The setting of the hard drive and the disk status depends on the connection plug between the hard drive and the hard drive cable. The disk that is usually connected to the middle of the hard drive line is the main disk, and the disk connected to the end of the hard drive line is the disk. When you set up the master, from disk in this way, you must set all the IDE connector device jumpers that are joined to the same hard drive line in the cable selection location.

Can determine the hard drive main, from the disk state 40 core hard drive cable is specially made. The method is to make the normal 40-core hard Drive line 28th (from the 1th red line or other mark start number) in the position between the two hard drive plugs, cut off after the tangent of the attention can not break other lines. The advantage of using a specially crafted hard drive cable to determine the main and disk state is that it is easy to use. When you need to swap the hard drive master, from the state as long as the connection of the hard drive cable plug location, you do not need to remove the hard drive to the jumper.

　　Second, the installation of dual-drive should be aware of the following matters

1, in addition or upgrade the hard drive, as far as possible to choose the same brand of hard disk. Compatibility issues may occur because of the use of different branded hard disks on the same hard drive line. If you encounter a situation where a hard drive is not detected or detected on a computer startup, in the confirmation of two hard disk jumper settings are no errors can be disconnected from the original use of the hard disk and then reboot, if the computer can detect a new disk, then the two hard drive compatibility problem. The workaround is to use the new hard drive on the second hard drive line. If you must use the same hard drive line, then swap the main and the two hard drives for a relationship.

In addition, if the newly added hard disk and optical drive and other devices together on the second hard drive line, pay attention to the optical drive and other devices, the main, from the disk settings and new hard drive conflict, otherwise there will be the motherboard can not detect the new hard drive or the original CD-ROM problem found.

2, pay attention to the problem of staggered disk characters. In the case of multiple partitions, the order of the hard disk partitions is somewhat erratic: the primary partition of the primary hard disk is still considered a C disk by the computer, while the primary partition of the second hard disk is considered d, followed by the other partitions of the first hard drive, which are arranged from E, followed by other partitions of the second hard drive, followed by the last letter of the first hard drive. This may cause the system or some software to be abnormal after installing the dual hard drive.

To add a second hard drive after the letter does not change, the solution has two: if you only use Win98, relatively simple, in the CMOS will be the second hard drive to none, but in pure DOS do not recognize the second hard drive. The second method is to partition the second hard drive after the two hard drives are removed, eliminating its primary DOS partition and only dividing it into extended partitions. The letter will not be interleaved. Of course, if the first hard disk has only one partition, there is no problem of the intersection of disk characters. In addition, some computer hard disk vendors provide some auxiliary software for solving the problem of staggered hard disk.

3, the installation of dual hard drive to pay attention to the cooling, two hard disk space can not be too small, and try not to overclocking.
