external hard drive not powering up

Mailbox often receives casual emails from siblings. This article is a masterpiece recently received. as a senior IT expert, I was amazed by my understanding of bios and the appropriate human metaphor for each part of the machine. I am a hard disk (I thought it was a joke at first, and I found it very touching only when I saw it)I am a hard drive and work in an

There are two fault prompts for Hard Disk Self-check by microcomputer: "HDD Not Detected (Hard Disk Not Detected)" and "HDD Control Error (Hard Disk Control Error) ". The following describes how to fix the vulnerability. First, wash your hands with water to clean the oil and sweat on your hands. At the same time, remove potential static electricity from your bod

moved by the HDD is USB to direct power, in some cases, due to insufficient power to the USB interface caused by the inability to read and cause hard disk damage. Recently, almost all of the mobile hard drives come with a separate external power supply or a PS2 adapter that takes power from the keyboard , and some uses a dual USB interface to power it. Therefore

As a storage device of the hard disk, the probability of failure is not large, the normal use of the hard disk, if not affected by external forces, generally will not be a problem, and we saw some such as hard disk circuit board burned hardware failure, but also because of the user's very operation caused. But in the m

when a second hard drive is damaged in raid. This is the system crashes, data loss, the site can not be accessed. Dedicated servers with a hard disk rack, the server can be hot-swappable SCSI hard drives without shutting down the computer, or you can replace the hard

computer does not recognize the mobile hard drive how to solve The computer does not recognize the mobile hard drive solution one: USB connector not open: On some old machines (including some brand-name machines) Although there is an external USB interface, but in the BIOS

than the bad sector size), divided the bad channel partition is not used to achieve the purpose of isolation. Isolation is only a temporary solution, it is recommended to replace the hard disk as soon as possible, because the bad channel will spread to avoid serious data problems later.As the disk's bad path continues to accumulate, it can have a devastating effect on your disk or flash capacity, and may even cause the

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

out the external large capacity cache, claiming that it can not rely on large capacity capacitance, can ensure data security and reliability It is true that the data loss of electricity is really greatly alleviated, but, in fact, SF2000 series master control inside, in fact, there is a certain amount of buffer existence. Therefore, external high-capacity capacitance is still one of the optiona

cleaning. However, this removal of the hard drive is to be careful. There is a great deal of learning. 1, can not touch the hard disk on the back of the circuit board, because in the climate is dry, people may have static electricity in hand, in this case, touch the hard disk on the back of the circuit board, "electr

HDD Low-level format Many friends are unfamiliar, in fact, each hard drive before the factory will be a low price format, and we buy the hard disk loading system, the hard disk partition format is advanced format. The average user rarely uses a low-level formatted hard

Windows is not only further enhanced in terms of Internet access, software usage, and resource optimization, but also greatly improved hard disk management. Hard Disk performance is the key to system performance. Therefore, Windows 2000 has made full considerations in this regard and provided sufficient optimization support. Hard Disk Management in Windows 2000 i

What if the computer doesn't read and move the hard drive? Computer does not read mobile hard disk solution one: 1, if it is a mobile hard drive USB interface line has two interfaces can be two interface plug into the USB interface, can provide

distance decrease, which reduces the average seek time and speeds up the hard disk access speed. Caching: A temporary location where the hard disk and external exchange data. Hard disk read/write data, the cache is like a transit warehouse, constantly write data, empty and then write data. At present, most of the

Your Mac's memory is usually not very large, plus a time machine backup using your Mac, which requires an external USB flash drive or hard drive. U disk storage space is small, we will not go to partition, directly to use on the Mac or Windows on it. So this is just about hard
