drive connector line instability, hard disk physical damage. Processing method: One, CMOS caused by the fault The correct type of hard disk in the CMOS (that is, the BIOS system) directly affects the normal use of the hard disk. Today's machines support the "IDE Auto Detect" feature, which automatically detects the

pursuit of stability, speed of the player or the love with the SCSI hard drive. Hard drives with different SCSI specifications: With 68-pins Wide SCSI connectors, you can transfer data using the 16-bit channel width. With 60-pins narrow SCSI connectors, data can only be transmitted in a 8-bit channel width. Jimper (jumper) settings, mainly used to adjust the

hard drive lights installed in the disk control array cabinet turned red, The system also prompts that the logical hard drive and the physical hard drive are not detected. I am not at ease, restart the computer system, and in the

computers often do not detect the hard drive what to do The computer often does not detect the hard drive solution one: There are several reasons for these: 1, the hard disk itself has a problem, may be broken, with tools to detect, bad can only send repair. 2, the data

Label:The failure condition of the hard disk can be divided into the following categories: 1. Control circuit failure Most of the external circuit of the problem is the power chip or spindle drive chip caused by the burn, due to hard disk circuit board quality problems, design defects, mains fluctuations, sudden power

, which must be based on the hard disk conditions to set up, otherwise it is likely that there will be 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. Third failure: A primary partition fails to start the hard

How to fix the computer hard drive? Hard Drive failure Scan One: Unable to find the hard drive situation For hard drives that appear with an "HDD not detected" error, fir

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

at the interface, to see whether the data line interface is blue, if it is blue for the USB3.0 interface. 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. Third, data transmission rate (data Transfer Ra

Warm tip: It is important to note that the hard disk is a sophisticated device, very fragile, before maintenance should first wash hands, release the residual static electricity before operation. Hard Drive failure Scan 　　One: Unable to find the hard drive situ

Top 10 hard drive saving strategies In order to effectively save the data in the hard disk, in addition to regular backup work, we also need to learn how to save the hard disk when the hard disk fails, or extract useful data from the bad area, minimize the loss. I.
