replacing internal hard drive

A recent X3650 old server for testing broke a hard drive, the hard drive is on the RAID1 group, the hard drive model is SAS 15K 73GB. Because it is an old machine, replace the bad hard

A malfunction phenomenon: hard drive light AlarmSecond fault analysis: HDD faultThree processing processes: On-Site view discovers that the host is configured with two 300GB hard drives and the system is functioning properly. The judgment host should have done Riad 1 (the Fdisk-l command shows the size of the logical disk as 300GB) Replace the

1. Before replacing the failure disk, confirm the operation status of the bad disk again. 2. Verify the status of the relevant LUNs and RAID group before replacing the failed disk. You must wait for the rebuilding to complete before continuing. 3. If a failed disk is already present and the hot spare is rebuilding (rebuild) RAID, you can replace the failed disk during the rebuild. If the rebuild complet

to promote their own professional software, it can repair the Physical Bad Sectors of the hard disk and does not affect the hard disk capacity, resulting in a daily price of more than 10 thousand yuan. Especially when Russia's PC-3000 entered China, this information was even more eye-catching. [Note: PC-3000 is a commercial professional hard disk repair integrat

the screen: DATA Error reading drive C: Abort, Retry, Ignore? "Analysis processing" causes this failure, one is the disk body wear or improper use of hard disk, resulting in the loss of internal hard disk information, the second is the disk repeatedly read and write, file connection confusion, the allocation of too

SAS hard Drive, is a serial connection to the next generation of SCSI technology, the use of serial technology to achieve higher transmission speed, and by shortening the connection line to improve the internal space. SAS is a parallel SCSI interface that develops a new interface. Improves storage system performance, availability, and scalability, and provides co

hard Disk Interface The current hard disk interface type is not much, mainly IDE, SCSI, SATA three kinds. Many times the IDE replaces the Ultra ATA, many people are accustomed to the Ultra ATA hard disk is called IDE hard disk, but need to explain that the concept of the IDE is greater than ata--in principle all

capacity. The internal parts of the mechanical hard disk are more complex than the solid-state hard disk, there are no motors and fans inside the solid-state hard disk, so in this aspect the solid-state drive will have a great advantage over the me

replace, and then turn on the power, The system will soon be able to identify the device you are accessing and put it into use. A real support for hot-swappable hard drives and optical drive prices can buy a few do not support hot plug of the same products, and the use of the extraction box + software, the average family can also have this ability, so that the value of the extraction box and

can also create a new partition before the bad way, if you don't divide the bad way into the new partition again. In general, do not do so, so as to avoid too many partitions and too fragmented. can affect disk performance. The shielding partition method only applies to the hard drive bad road to compare the situation, if the hard

temperature, the difference is also possible. Generally speaking, the motherboard, hard disk temperature is lower than the CPU, the motherboard is generally 40-60 degrees between the temperature is acceptable, hard disk temperature, the normal IDE or SATA hard disk temperature should be below 55 degrees is normal. What happens when the

, using the general use of the mobile hard disk box, it is best not to plug in the long-term work on the computer, mobile hard disk is used to temporarily exchange or store data, not a local hard disk. It is always possible to work in harsh environments compared to internal hard
