How many hard drives can a computer have?

The computer can install 4 hard disks; as many hard disks as there are hard disk interfaces on the computer, and the location of the computer's optical drive can also be used to install hard disks, so many laptops remove the optical drive and replace it with a hard disk Install it; the IDE interface on the motherboard can connect two hard disks, namely the master disk and the slave disk, and the motherboard has two IDE ports, namely IDE1 and IDE2, so in theory, a personal computer can connect four hard disks.

How many hard drives can be installed in a computer?

A computer host can install 2 hard disks. You can install as many hard disks as there are hard disk interfaces on your computer. Moreover, the position of the computer optical drive can also be used to install hard disks, so there are many laptops. Remove the optical drive and replace it with a hard drive.

The IDE interface on the motherboard can connect two hard disks (i.e., master disk and slave disk), and the motherboard has two IDE ports, namely IDE1 and IDE2, so in theory Basically, a personal computer can connect four hard drives.

If you use an adapter card, you can connect more drives. Finally, for multiple hard drive installations, it is a dual hard drive installation because the hard drive installations on IDE1 and IDE2 are exactly the same.

Before starting to install dual hard drives, users need to consider some issues first. The first is whether there is enough space, please install a second hard drive; secondly, whether the power supply is sufficient. If there is insufficient power when the computer is running, the hard drive head will keep resetting and the hard drive will be damaged.

When installing dual hard drives, please note the following:

1. When adding or upgrading a hard drive, please try to give priority to using the same hard drive with the same brand.

Because the compatibility of hard drives of different brands may appear on the same hard drive. The solution is to put the new hard drive on the second hard drive. If you must use the same hard drive cable, change the primary drive for both hard drives based on the relationship.

In addition, if the newly added hard disk and optical disk drive are connected to the second hard disk online, please pay attention to the master device of the optical disk drive, etc., and the slave disk settings will not conflict with the newly added hard disk.

Otherwise, the motherboard may not be able to detect other hard drives or find problems with the original optical drive.

2. Pay attention to the issue of letter spacing.

In the case of multiple partitions, the order in which the hard disk partitions are divided is a bit strange: the computer still regards the primary partition of the main hard disk as the C drive, and the primary partition of the second hard disk as the D drive. , then another one from the first hard drive.

These partitions are separated from the E drive in turn, and then the other partitions of the second hard drive are converted in sequence to the last drive letter of the first hard drive. After installing dual hard drives, it may cause system or certain software abnormalities.
