After starting work, due to the need for work, I specifically purchased a 500G mobile hard disk on the Internet, when I was purchased from Seagate official channels, the price is not very high, hundreds of dollars will be done. When I bought this Seagate Mobile Drive, my usual work of the important files will be saved to this mobile hard drive, for the work to bring a lot of convenience. At that time, I was quite confident about the hardware of the mobile hard disk, and thought it would not have

In fact, most motherboards are supported USB-HDD boot, the key is to set the correct. Different motherboard BIOS options, it is best to find detailed motherboard instructions to follow the settings. The first thing to do is to turn on USB boot device support, such as finding options like "USB Storage Legacy Support" or "USB Storage Function" and setting it to "Enabled."

Recently, the notebook of the small series has a post situation, the NTFS partition mode installed in the Win7 of the boot appears self-test. There is a Win7 post, which is just a few of these common situations: 1. Illegal shutdown 2. Hard drive Bad Road 3. System problems 4. Hard drive not working properly Because NTFS partitions are relatively stable, self-test is rarely seen in the case of illegal shutdown. If there is a post, then let it self-test, restart generally did not, if there a
