The computer only displays the solid state drive and not the mechanical hard drive.

The newly purchased computer only has a solid-state drive. I added a mechanical hard drive and the cables are connected. Why is there no display when booting...

1. This is often a mechanical problem. The jumper settings of the hard disk are incorrect. To add a hard disk to the computer, you need to set the order of the master disk and the slave disk in the BIOS, and maintain the correct hard disk jumper. Your computer originally had a solid-state drive, so this solid-state drive must be the main disk for booting the system, and the mechanical hard drive added later should be set as the slave disk.

2. If it is not found in the device management, it means that the operating system does not recognize the mechanical hard disk. First, shut down the computer, check the connection of the data cables and signal cables of the two mechanical hard disks, and replace the data cables if necessary. Then boot into the BIOS and first confirm whether all hard drives can be detected in the BIOS. The BIOS doesn't show anything, so it's a hardware failure.

3. This independent graphics card does not matter. After attaching the mechanical hard disk, boot into the BIOS and change the boot order to the solid-state hard disk to boot first. After all, the system is installed on the solid state. If the mechanical hard disk starts first, there will be no system. .

4. The mechanical hard drive cannot be seen when the computer is turned on, but the mechanical hard drive can be recognized and opened in the same BIOS and PE. This situation is usually caused by insufficient power supply of the mechanical hard disk or a problem with the operating system. You can change the hard drive power supply interface or try another power supply. If the problem persists, reinstalling the operating system can usually solve it.

What to do if win10 does not display the mechanical hard drive

First select My Computer and right-click the "Properties" button. Then in this interface, click on the "Device Manager" option. Then in this interface, click on the "Disk Drive" option. Then in this interface, click "Action" and select the "Scan for hardware changes" option.

Right-click win10-1803, in the right-click menu: Change drive and path, click: Add in the change drive letter and path dialog box that pops up in win10-1803. The "Add Drive Letter or Path" dialog box will continue to pop up. You can see: Assign the following drive letters -e, click: OK.

Right-click "This PC" on the desktop and click "Manage". Click "Disk Management" to view the mechanical hard disk partition status and other information. Mechanical hard drives are prone to failure. If bad sectors occur, you can try to use a hard drive regenerator to repair them.

First right-click on the Start menu and then open the "Disk Management" option. After opening Disk Management, check whether there are two hard drives or only one solid-state drive.

Or pass directly. diskgenius to view specific partition data. Of course, because this type of software is two-sided, it can view the hidden data in your lighting area, but there is also a certain chance of damaging your data, so you must be cautious or operate it with caution.

Install the solid-state drive, but the motherboard cannot detect the mechanical hard drive

First check whether the computer recognizes the solid-state drive, that is, whether the data cable is plugged in properly. Right click on My Computer and select Properties.

First of all, please check whether the hard drive power connection is correct and make sure the power cord is firmly connected. Also, consider replacing the power cord with another power plug. If the data is accidentally lost, it is recommended not to read or enter new data into it at the first time. You can try to use some data recovery software to recover the overwritten files.

The system does not find or recognize the hard disk after booting. This situation causes the system to be unable to start with a hard disk. Even if we start the computer through other means, we cannot find the hard disk.

When turning on the machine, touch the mechanical hard drive and check whether there is a feeling of rotation. Check (or replug and unplug) the power cable and the host SATA cable to prevent poor contact. Finally try to replace the motherboard SATA interface. There is also the motherboard BIOS SATA setting to see if all SATA ports are open.

When you turn on the computer, touch the mechanical hard drive to check if it is working. Feel the rotation, check (or re-plug and unplug) the power cable and the host SATA cable to prevent poor contact. Finally try to replace the motherboard SATA interface. There is also the motherboard BIOS SATA setting to see if all SATA ports are open.

If you can’t see it, it means that the mechanical disk is not mounted. Have you dismantled the computer or dropped or squeezed the laptop before? If not, it means there is a problem with your newly installed system. The motherboard driver does not match. It is recommended to flash it back. Official system.

If you can’t check it out, it means you installed it incorrectly. Please disassemble and reinstall it.

% probability is that the hard disk is burned out. First check the memory slot, re-insert the hard drive connection slot, and then smell the motherboard to see if there is a burnt smell. It is also possible that a component on the motherboard is burned, but the probability is not high, and burned components on the motherboard will affect booting.

First go to the BIOS to see if the mechanical hard drive is displayed. If not, disassemble the case and replug and unplug the data cable and power cable on the mechanical hard drive.

It will not be displayed when you first turn on the computer. For example, if you insert a USB flash drive when turning on the computer, it will not be displayed. The drive letter can only be found after turning on the computer. You need to insert a USB flash drive, and the system needs to load a driver for it. Scan the driver and plug it in correctly.

Why does the mechanical hard drive sometimes disappear and only the solid-state system disk remains?

1. If it still doesn't work, the hard drive may be damaged. Please repair or replace the hard drive with a new one (if you can't fix it yourself, just check it out).

2. It is also possible that a component on the motherboard is burned, but the probability is not high, and burned components on the motherboard will affect booting.

3. The mechanical hard disk cannot be recognized by the computer. Reason: Conflict with system settings. New systems such as win2000, win7, and xp directly support removable hard drives, while old systems below win98 must install drivers to recognize them. The USB interface has poor contact.

4. It is caused by the connection problem of the hard disk’s data cable or power cable. It is recommended that the user try to replace the hard disk’s data cable.

5. First check whether there is any problem with the data cable and power cable. Try changing the computer. If the problem with the computer and cable is eliminated, there may be a problem with the hard disk itself. Generally, the slave disk has certain requirements on the power supply. In the long run, Use may cause the mechanical hard disk to develop bad sectors and eventually become unrecognizable.

6. The mechanical hard drive cannot be seen when the computer is turned on, but the mechanical hard drive can be recognized and opened in the same BIOS and PE. This situation is usually caused by insufficient power supply of the mechanical hard disk or a problem with the operating system. You can change the hard drive power supply interface or try another power supply. If the problem persists, reinstalling the operating system can usually solve it.
