convenience of "Cable select", note that all ide devices must be set to "Cable select". In addition, when the hard disk and the optical drive are mounted on the same data cable, "Cable select" may be invalid-the optical drive does not support "Cable select "! In addition, "Cable select" also requires data line support. If a poor data line is used, errors may also occur. Therefore, for beginners, set the hard disk to "master" or "slave. The "Cable select" setting of the IBM hard disk is very sim
the ATA, such as Ultra Ata, ATA/66, ata/100 and so on.Early IDE interfaces have two transmission modes, one is PIO (programming I/O) mode and the other is DMA (Direct Memory Access). Although the DMA mode system resource consumption is small, but requires additional drivers or settings, so the degree of acceptance is lower. Later, in the case of higher speed requirements, the DMA mode is more efficient, the operating system starts to support directly, and the manufacturer has introduced the inc
The performance of a single disk 1TB HDD since its inception, to bring users a surprise, whether as the main disk, or as a HD hard disk, a single disk 1TB hard drive than the performance of the old hard drive significantly improved.

Due to SSD read/write latency and iops (I/O perSecond) These two aspects have about three orders of magnitude advantage over traditional mechanical hard drives, which has led some people to doubt the prospect of mechanical hard drives, I think SSD will be the first choice in the cloud computing era and will completely re

device is using a terminator, the SCSI card will not be able to find a later SCSI device. SCSI also does not work if the last device does not use a terminator. The Terminator is made up of resistors, located at the end of the SCSI bus, to reduce the interaction between the signals and maintain a constant voltage on the SCSI chain.Most SCSI devices are built-in terminators and use a jumper to control on/off. SCSI devices are now highly intelligent and can automatically control Terminator On/off,

Today, I was just testing a ZFS array to clearly check the data and see the results, so I just analyzed the reason.In this case, the first thing to do here is to introduce a concept that is not often accessible to ordinary people:ber hard drive Ber, English is ber (Bit Error rate), is a very important parameter to describe the performance of hard disk, is a parameter to measure the possibility of hard disk failure.Thi

The customer sent a piece of Seagate st380011a hard disk for data recovery. The fault is that the disk is not recognized or knocked on the disk. Next we will follow the data recovery senior engineers to learn how to repair the data while protecting the data.
We will analyze it in several steps, and we will detect the failure of the hard disk.
First, check the hard disk appearance and circuit board.

MSI GT70 is one of a number of hardware vendors that have started upgrading their products as Intel officially releases the fourth Daicouri processor Haswell. The game's audio-visual notebook, which sells up to $2799 (about 17171 yuan), is not only powered by Intel's newest Haswell processor, but also has the Nvidia GeForce GTX 780M discrete graphics card, which is the world's fastest notebook graphics card. This new range of features means that MSI GT70 has more powerful graphics and overall pe

Now the market repair plate is still quite a lot of light from the appearance, packaging, a little difficult to distinguish oh.
Shopping channel is very important, do not recommend a treasure purchase, purchase suggestions to choose well-known electric dealers, or store, remember to request invoices.
