More and more users have chosen the model for installing SSD drives when they buy Macs. SSD can make OS X run more smoothly, but its 256G, 128G capacity, more and more can not meet the needs of people. Connecting an external hard drive to your Mac is a temporary solution. OS x is well compatible, making most external

the spring force and quickly return to the docking frame when an accidental power loss occurs. 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

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

are not recognized can also be repaired, but it is difficult to partition when the 0 channels are bad.This is misleading. 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

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

The biggest function of the mobile hard disk is the storage function, the equivalent is the giant u disk, is the storage capacity and the appearance big volume storage tool. So What are the important things to note when using the giant U-disk? Here's what to share with you about using your mobile drive. currently on the market for mobile

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
