seagate hard drive issues

Test hard drive Bad Sectors in CentOS Hard Disk status testing tools: smartctl, Badblocks, hdparm You can quickly see whether the hard disk is healthy by using smartctl. The command is as follows: [Root @ qy ~] # Yum installsmartmontools-y Start SMART # Smartctl -- smart = on -- offlineauto = on -- saveauto = on/dev/sd

Factory is as the master disk, which is not required when only one hard drive is installed, but when multiple hard drives are installed, the hard drive jumper needs to be reset. The jumper on the hard disk is simpler, and the jum

Mobile hard drive believe that everyone will not be unfamiliar, similar to ordinary hard disk, only the mobile hard disk emphasis is portable mass storage products, so the mobile hard drive more than the use of USB or IEEE1394 fas

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. Nine, Brand Brand, this is in fact only in genera

, same as the Scis interface. Fibre Channel was not originally designed for hard disk design and development of interface technology, is designed for the network system, but with the storage system on the speed of the need to gradually apply to the hard disk system. The Fibre Channel hard disk is developed to improve the speed and flexibility of the multi-disk st

Now most people have been accustomed to buy online accessories, but there will be not at ease, such as the purchase of hard disk will ask the author how to query the authenticity, in fact, check the authenticity of the hard drive is very simple, only need to login official website, simple one-step input serial number can be. First, let's look at the west number

good news is that hard disk manufacturers are beginning to provide hard disks with built-in full disk encryption. The Momentus 5400 FDE.2 hard drive manufactured by Seagate is a leader in this field. Compared with ATA Hard Disk l

, the Seagate SATA3.0 hard drive has the same performance as the SATA2.0 hard drive in the average speed test, and also leads the western data 100 million to the Raptor hard drive. Visi

mode, in fact, the serial technology is faster than the transmission speed of parallel technology. 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. Look at this picture, this is the image of the SAS hard drive. Th

Sata's full name is serial Advanced Technology attachment (Serial Advanced technology Attachment, an industry-standard serial Hardware driver interface), which is made up of Intel, IBM, Dell, APT, The hard disk interface specification proposed by Maxtor and Seagate Corporation. The Serial ATA 1.0 specification was formally established in 2001 by the Serial ATA Board of Intel, APT, Dell, IBM,

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 external devices. The IDE's English is all called "Integrated

instructions on Jumper settings on the hard disk surface. Taking Seagate hard disk as an example (8), there are four main settings: "Master or single drive" (it indicates that the hard disk is set as the primary disk or only one hard
