A hard disk is an external storage device for magnetic media, on each side of the platter, a plurality of concentric circles with the axis of rotation and a certain magnetic density are divided into tracks (Track), each of which is divided into several sectors (sector), and the data is stored on the hard disk by sector.

motherboard.
Enabled: Parallel IDE port function (preset) is allowed.
Onboard IDES operate mode (motherboard built in IDE priority setting)
The device priority (default) on the PATA is Pri ide:pata port.
The device on the SATA is Pri ide:sata port is preferred.
Onboard sata-ide (motherboard built-in SATA port function set)
Disabled: Turn off the SATA port on the motherboard.
SATA: The SATA port on the motherboard is used as a normal SATA port.
motherboard is turned off, and if it is not set to open, Then Windows naturally cannot detect the removable hard drive.
To solve this problem, we can reboot, enter the CMOS Setup window, and in the "Pnp/pci CONFIGURATION" column, "Assign IRQ for USB" is set to "Enable", This allows the system to assign an available interrupt address to the USB port.

So to keep the head of the drive in the disk radius, the drive motor (seek motor) of the head arm will continue to pass current. And let the head arm in the hard disk idle for a few minutes immediately after the unloading action, return to the docking rack, both to hel
the temporary access to the hard disk, as far as possible to put it properly, preferably fixed on the hard drive bracket, do not hang casually on the chassis. Many users think that just temporary exchange of data, put the hard drive casually placed. In this case, the
Jump out of hard drive misunderstandingSeveral common sense questions that have been misleading Gao Peng for many years are:1. Hard Disk logical bad sectors can be repaired, but physical bad sectors cannot be repaired. The actual situation is that bad channels are not divided into logical and physical bad channels. I don't know who invented these two concepts. Th
often in the monitoring of the operation of the virus, in this state to remove any files related to the antivirus program, the system will pop up "delete file error, Access denied please make sure that the disk is not full or write-protected with this error prompt. And when we switch the system to Safe mode, the reason is able to delete the AVP format files are normal, because in the system security mode, Kaspersky antivirus program often will not be automatically loaded with the system, so tha

For example, if you have not collected and studied foreign-language materials for a long time, you cannot say that you have used them as your creed for a long time. There are many professional hard drive repair forums in foreign countries, where you can find that

Why does frequent read/write damage the hard disk?
The lifetime of the head is limited. Frequent reading and writing will accelerate the wear and tear of the head arm
my turn to be busy with my c brother.Among the brothers in the chassis, I like hard disks best. He has a big brain, remembers many things, and remembers well. He saidThe speed is very slow, and there are few mistakes. This shows that he is very deep, so I feel so. The CPU also thinks so, but he is stupid and forgets who the hard disk is every time. During self-c
checking the integrity of the backup is also important to protect the data on the hard disk, because the Windows operating system is damaged and can be reload, and if the hard disk partition table is broken, the system will not recognize the hard drive and the problem is much more serious.

Introduction to Interfaces
IDE interface
(Integrated-drive-electronics) is now commonly used external interface, mainly connected to the hard disk and optical drive. Using 16-bit data parallel transmission mode, small size, fast data transmission. An IDE interface can only receive two

3, look at the pins, under normal circumstances USB2.0 is a row of 4 pins, USB3.0 is the front 5 pins, 4 pins in the back row.
4, see Speed, General USB2.0 of the actual transmission speed of mb-40mb/s, and USB3.0 transmission speed can reach 60mb-140mb/s, you need to pay attention to the premise of your computer motherboard support USB3.0.

needle in a haystack only happens occasionally, therefore, we absolutely do not need to let Desktop search software in the system when a free, to automatically index files, and we just turn off the desktop Search software automatic indexing function, we can ensure that the hard disk in the system can be free to "rest" effectively. For example, when we turn off t
