2.Why the computer can not detect the SSD?

Generally speaking, there are two possibilities: (1) Insufficient power supply: plug the USB power transmission line connector attached to the SSD to the USB slot at the back of the computer to ensure that the computer has enough current to supply the hard disk. And do not use USB Hub, extension cord or other USB devices to avoid insufficient power supply, causing the computer to fail to read the hard disk. (2) No new sector has been added: Under Windows XP/Vista/Win7 operating system, please go to Disk Management to confirm whether there is an SSD installed.
