1. SSD interface connection error

If it is a mid-to-high-end Motherboards are generally equipped with multiple M.2 slots. When players connect an SSD, they must also consider the location of the slots.

Generally speaking, not all M.2 slots support the same protocol. For example, although the GALAXY B460 GAMER is equipped with two M.2 slots, only The channel of the first slot close to the CPU supports both NVMe protocol and SATA protocol, while the second slot only supports M.2 NVMe SSD. If the user connects an M.2 SATA SSD to the second slot, The motherboard may not recognize the SSD.

Therefore, you must ensure that the M.2 SSD is installed into the correct M.2 slot so that the motherboard can correctly identify the hard drive and perform as it should.

In addition, if your M.2 SSD is not properly connected to the interface, the computer will not be able to recognize the hard drive. You need to ensure that the SSD has been installed correctly.

Some traditional devices do not support the existing UEFI boot mode of the new motherboard. CSM is here for this purpose. CSM is also called the compatibility support module. It is compatible with both UEFI and non-UEFI boot modes. Turn on CSM, the computer will perform a step to detect hardware functions when it is turned on. If CSM is turned off, the computer will only support UEFI mode. The computer will skip the power-on self-test step and speed up the boot-up speed.

Nowadays, many motherboard manufacturers set CSM in BIOS to off by default to improve computer startup speed. However, after turning off CSM, the BIOS may not be able to recognize the M.2 SSD, so if your computer cannot recognize the M.2 SSD, you can try turning on the CSM.

Different motherboard BIOS have different locations to open CSM. After restarting the computer, keep pressing the DEL key to enter the BIOS, and then follow the instructions in the manual to open CSM.

In the second case, you open CSM, but the computer still cannot enter the system. It may be because the system disk recognized by the computer is not the M.2 SSD you want to identify. According to the instructions of different motherboards, choose priority. Start the system's hard drive, save the settings and then restart the computer.

In the third case, in addition to the system disk, you have connected a second new hard disk to the computer. After booting, you find that the computer does not display the hard disk information. This is because the new hard disk is required. Partitioned.

Right-click the “This PC” icon and select “Manage”.

Select "Disk Management" under "Storage" in the left menu bar, and you can see the existing disk information on the computer in the right status bar.

If your new disk shows "Not Initialized", select the disk and right-click, select "Initialize Disk" to initialize the disk, and then perform partitioning operations so that the computer can access your new disk.

Through the above method, you can solve the problem that the win7 system computer cannot recognize the M.2 solid-state drive. I hope it can help everyone
