In order to accommodate now "volume" is more and more big software, believe a lot of friends have bought a higher capacity of the new hard drive, but when you begin to put into the old hard drive, as if thought two hard disk used together? This can not only remove let old hard disk early retirement, and still can let you have more disk space, since a lot of good, that you still etc. What? Come and join our double the hard disk installation trip!
Before installation, the matters needing attention
Before installing double hard disk must first check computer internal basic situation, such as whether to have installed the second hard disk space, data cable have a spare interface, computer power supply power is able to support two pieces of hard disk and stable operation, etc. These conditions for installation double hard disk is important for all.
Second, the jumper Settings
The next two hard disk is to set the jumper, a set is given priority to disk (Master Device), another set to from the plate (Slave Device). There is a problem we should make it clear, that is what is hard disk setup disk more reasonable, many friends think will higher capacity of hard disk is a dish, this view is wrong, the correct method should be better performance of the hard disk is a disk. Give a simple example, you had a piece of Seagate cool fish Ⅱ and gb hard drive (7200 RPM), then bought a piece of sixty gb of Seagate U6 hard disk (5400 turn), then you should put cool fish Ⅱ and gb set is given priority to disk, because its speed is quicker.
Different between hard disk jump line method may be different, but basically the same. Below we will in a Seagate cool fish Ⅳ (7200 turn) and a maxtor diamond circle pins at generation (5400 turn) as an example, explain jumper setting method.
First of all we want to look at the two were hard jump line shows that the general description in hard disk positive or negative. Then according to the instructions will Seagate cool fish Ⅳ mainly a dish, diamond circle pins at a generation from the plate (note: if two hard disk all use a data line, can not to jump line Settings). Complete jumper setting, will be two hard disk were installed inside the case to the corresponding position, and connect data and the power cord. When the connection cable must pay attention to the blue end of the motherboard IDE interface connected, but if you use a early DMA/and data line, it's not this requirement. This step, hardware installation work is all done. Then we can open the computer power supply, and into the motherboard BIOS, can see BIOS has automatic detection out two hard drive capacity and subordination, it shows double hard disk installed successfully.
Three, data line selection
In addition to hard disk with Master and Slave jump line outside, still a Enable cable select jumpers. If the user set the jumpers, so hard disk between parent-child will be determined by the data line. This is a very rare master-slave plate setting method.
But at the moment, is not to be two pieces of any hard drive a master-slave disc jumper setting, and need two pieces of hard disk will jump line changes to "Enable Cable Select" state. And the connection must pay attention, whether using and core DMA / 33 line, or 80 core DMA / 66 line, away from the main board of hard disk interface is always connection main dish, and close to the main board of the interface of the hard disk has always been perceived as from the plate. In fact the data line setting method to determine the master-slave disc relationship, is to install double hard disk is very agile methods. For instance, you can take two pieces of hard disk are made bootable startup disk, as the main dish appear hardware fault, just put the hard disk in received Master interface, it will become a system disk. This method is especially suitable for the user and often replace your hard disk drive.
Four, plate character alternative solutions
Below, we again use double hard disk that often appear "plate character staggered" problem. The so-called "plate character staggered" is when we install the double hard disk later, hypothesis for each drive each three area, then the normal situation should be the main dish each driver in the front, and from the disk drive in. But the actual situation is often, the main dish C, E drive between pile in the dish F drive, is also will appear, it will bring a lot of use to users of trouble, such as lead to a single hard disk in the original installation software operation is not normal, etc. There are a few kinds of method can solve the "plate character staggered" problem.
1, shielding method
For the two pieces are primary partition of the hard disk, it can be in the BIOS setting primary hard drive is set to AUTO, from the hard drive is set to None. In the boot into the Windows after can avoid "plate character staggered", the same way for Linux operating system also can be used
If double hard disk primary partition are equipped with different operating system, then can through the change in the BIOS setup disk state, thus start another piece of hard disk operating system. But this method also has certain limitation, which is in a single DOS mode will not be able to find in the BIOS shield off of the hard drive, cannot carry on the reading and writing the operation.
2, partition method:
This method is more practical, the method is only in the main drive to establish primary partition, and all from the hard drive is divided into extended partition, and then again in the division logic partition, which can avoid the "plate character staggered" phenomenon occurs, but in this way is easy to remove from the hard disk data, so the operation will be done before the backup work.
Other avoid "plate character staggered" to the problem and use Partition Magic and so on software Settings, part of the hard disk vendors also introduced a special setting software.
