What if the computer can't read the mobile hard drive?
First, the system-driven reasons
1, USB is not recognized by the computer, boot press F8 into the safe mode after the exit, select the restart or shutdown in the boot, you can enter the normal mode.
2, if the failure is still, using system disk repair, open a command prompt input Sfc/scannow return (SFC and/between a space), insert the original system disk repair system, the system will be automatically compared to repair.
3, if the failure is still, set the optical drive in the BIOS for the first boot device Insert system installation disk press R to select "Repair Installation" can be.
Second, set the CMOS parameters
1, the system can not detect the situation of USB hard disk, this is mainly because the motherboard default CMOS port is turned off, if it is not set to open, then Windows naturally cannot detect the mobile hard drive.
Third, USB extension cord failure
The USB interface type mismatch causes the removable hard disk to be unusable. Because a high-speed mobile device is plugged into a low-speed hub, the device may not be installed properly, as long as the connection line is replaced with a USB 2.0 standard to resolve the failure.
Attention matters
After you install the driver, you can view the removable hard drive from Device Manager, but there is no corresponding letter identifier in the resource manager, which is the result of improper system setup.
Additional computer hard drive can not recognize the solution:
1, the system can not find the hard drive after the boot or can not recognize the hard drive
After the boot system does not recognize the hard drive, we first think of the hard drive compatibility mode problem, but there is no hard drive and the motherboard compatibility problem, so this idea can be ruled out. The main reason for this type of failure lies in the connection between the hard disk and the motherboard, and when this happens we try to replace the connection cable between the motherboard and the hard disk. If the problem is still unresolved, you can see whether the master-slave line is set correctly or if the hard drive is running with strange noises;
2. Improper BIOS setup causes the computer to not recognize the hard disk
The BIOS of the motherboard can also set the hard drive Normal, LBA and large, and other working modes, we need to be based on the hard drive to set up, otherwise there is a good chance of other problems. This kind of situation is not difficult to solve, as long as the motherboard BIOS instructions and the hard disk itself, the correct settings can be resolved.
3, hard disk partition problem caused hard drive can not be recognized
Our computer's hard disk is used to partition it so that there is a difference between the primary partition and the logical partition. If there is a problem with the primary partition and the computer does not start properly it is also common that we need to enter the FDISK/MBR command in DOS mode by booting it, because in the FDISK command file already contains a master leader program for a hard drive, Microsoft has already thought about this problem for us, so we just need to make some changes to it.
