Early IDE interfaces have two transport modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although DMA mode system resources are low, they require additional drivers or settings and are therefore less acceptable. Later, in the case of higher speed requirements, t

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
". Shortly after, the then microcomputer maker Compaq and the hard drive maker Seagate, Quantum and Connor jointly proposed a similar technology called IntelliSafe. With this technique, the hard drive can measure its own health metrics and transmit the parameter values to

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

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 drives. Now the USB interface of the mobil

You can quickly see whether the hard disk is healthy by using smartctl. The command is as follows:

capacity, the lower the average seek time. When the capacity of the single disc increases, the seeking action and the moving distance of the head are reduced, which reduces the average seek time and accelerates the hard disk speed. Therefore, in the purchase of hard disk products should be as far as possible to choose the average seek time short products.

Easier cabling-the flat, wide line of SCSI cables will no longer be used.
Wider scalability-compatible with SATA.
Lower costs-with the advantage of simplifying the internal connectivity design, you can reduce design costs by sharing components.
