【 Weak current College 】 HDD slave settings

In order to be able to accommodate today's "volume" increasing software, I believe many of my friends have already acquired the higher capacity of the new hard drive, but you will be taken of the old hard drive, is thought to be one of the two hard drive and use it, this not only eliminates the old hard drive to retire early, but also can make you more hard disk space, since the benefits, that you still waiting for? please join our dual hard drive installation tour!

I. installation considerations
Installation dual hard drives before to view basic information on the inside of the computer, such as whether there are installing a second hard disk space, data cables have a spare computer interface, power is able to support the stable operation of the two hard drives, etc. These conditions for installing dual hard drives are very important.

Second, jumper settings
Next is set two hard drive jumper, one master (MasterDevice), another set to slave (SlaveDevice). Here's a question we have to figure out is what hard drive set as the main dish is better, a lot of friends that you want to add capacity, greater hard drive set as the primary disk, this view is wrong, the correct approach is the better hard drive set as the primary disk. Take a simple example, you might have a Seagate Kuyu Ⅱ 20 G B hard disk (7200 RPM), and later bought a Seagate hard drive 60GB U6 (5400 ext), then you should put kuyu Ⅱ 20 G B set as primary disk, because it is faster.


Figure 1 kuyu Ⅳ hard drive jumper description

Different hard drive jumper between the methods may differ, but basically similar. Here we take a Seagate Kuyu Ⅳ (7200 RPM) and a Maxtor xingzuan generation (5400 ext), for example, explain the jumper settings.


Figure 2 excellent generation hard drive jumper description

First of all we have to look at the two hard drive jumper description, the description is located on the hard drive of the generally positive or negative (shown in Figure 1, Figure 2). Then follow the instructions to Seagate Kuyu Ⅳ set as primary disk (Figure 3), the excellent generation set as slave (as in Figure 4), (Note: If two hard disks to use a data cable, you can not make jumper settings). Complete the jumper setting two hard drives are installed to the appropriate location within the chassis, and connected to the data and power cables. In the connection cable to the blue side of the IDE interface is connected to the motherboard, but if you are using an earlier DMA/33 cable, without this requirement. After you complete this step, hardware installation work is complete. Next we can turn on the computer's power supply, and enter the motherboard's BIOS, you can see the BIOS has been automatically detected two hard drive capacity and master-slave relationship, dual hard drives have been installed successfully.


Figure 3 will be set as the primary disk kuyu Ⅳ

III. cable select
From Figure 1, 2, we see that the hard drive in addition to a Master and Slave jumper, a Enablecableselect jumper. If the user set the jumper, so the master-slave relationship between the hard disk will be determined by the data cable. This is a relatively rare slave setting method.



Figure 4 the excellent generation is set to slave

But this time you cannot place the two hard drives to any one slave jumper settings, and the need for two hard drives are jumper changes to the status of "EnableCableSelect". While the connection when it should be noted that, regardless of the 40-DMA/33 line, or 80-DMA/66, away from the motherboard of a hard disk interface is always connected to the master, and close to the main Board of the hard disk interface is always regarded as slave. In fact, a data line sets the method to determine the slave relationship is installed dual hard drives very flexible tool. For example, you can use two hard drives are made into a bootable startup disk, when the master of a hardware failure, the hard drive swap on receiving the Master interface, it is a system tray. This method is particularly suitable for regular and replace the hard drive of the user.

IV. Letter-solutions
Let's say you use dual hard drive regularly appear in the "letter to a staggered" issue. The so-called "letter to a staggered" is when we install a dual drive, assuming that each of the hard disk is divided into three zones, the normal situation should be the primary disk in the drive, the drive from the disk. But more often than not, the master of the C, E drives into the slave's F drive, also is to occur, it will give the user a lot of trouble with, such as on a single hard drive in the original installation of the software is not running properly. There are several ways to solve the problem of the "letter to a staggered".

1, shield law
For the two pieces are primary partitions of hard drive, in the BIOS settings will be the primary hard drive is set to AUTO, the hard drive is set to None (shown in Figure 5). This in turn into Windows after which you can avoid the "letter to a staggered", as this approach is also applicable for the Linux operating system

If a primary partition of two hard disks are equipped with different operating systems, you can change the BIOS settings in the status of your hard disk to start the other operating system on a hard disk. However this approach has certain limitations, that is, in a single DOS mode will not be able to find in the BIOS screen off the hard drive, cannot read and write operations.

2. partition method:
This method is more useful, it is only in the primary hard disk on the primary partition and the partition from the hard disk all as an extended partition, and then in one partition logical partitions, so you can avoid the "letter of staggered" phenomenon, but in this way is very easy to remove from theThe data on your hard disk, so the operations must be done well before the backup job.


Figure 5 setting the main, from the hard drive status changes

Other avoid "letter to a staggered" problem still use PartitionMagic, software settings, some of the hard drive manufacturers have also introduced a special setup software.
