Why can t I connect two hard drives to my computer?

In this case, the most likely thing is that your hard disk does not have a master disk, a slave disk, and you can solve it according to the following methods:

Plan A: If the hard disk and the optical drive are on the same line, set the hard disk as the master disk and the optical drive as the slave disk according to the jumper settings instructions on the hard disk.

If two hard disks are on the same cable, set them as one slave and one primary according to the jumper settings instructions on the hard disk, for example, set the installed system as the primary disk and set the other hard disk as the slave disk.

Plan B: Install the disk of the installation system on the data cable at the near IDE interface end, connect it to the remote end, and clear any jumper settings on the hard disk.

Note: Plan B must be supported by the motherboard.

It's a problem with the hard disk jumper settings, and it should be enough to select the jumpers behind the hard disk as CLS.

It is definitely the hard drive's master-slave jumper that is not set up correctly.

The motherboard is poor, it is best to look at the manual of the hard disk, what is the bottom requirement of dual hard disks.

Is it the master-slave jumper of the hard disk that is not plugged in.

Could it be that the power supply is not enough?

Are you not the master and slave jumper of the hard drive not set?

Laptops can be connected to two hard drives, most of which do. Notebook, the main disk must have a hard disk, and the second hard disk is generally connected to the optical drive. or msata and interfaces.

Many newer laptops have interfaces for SSDs. There are generally two kinds, one is MSATA and the other is, also called NGFF. Can be connected to an SSD.

But it can only be connected to an SSD. It forms a dual-hard drive structure with the main hard disk to form an SSD and a mechanical hard disk.

If you don't have these two interfaces, but you have an optical drive, you can buy an optical drive conversion rack, and connect the inch hard disk to the optical drive bit, which can also form a dual hard disk. But some thin laptops don't have mSATA and, and there is no optical drive bit, so you can only use a hard disk.

Notebook computer (abbreviation: notebook, nb), also known as notebook, laptop or laptop computer in Chinese

A laptop computer is a small, portable personal computer that typically weighs 1-3 kg. The trend is to be smaller and lighter, but more powerful.
