Anonymous users2024-02-07Hard disks all support RAID, but it depends on the interface type of your RAID array, there are IDE, SATA, SICI hard disks are not fake, pay attention to the packaging when buying (some brands will use vacuum bag packaging), bulk hard disks pay attention to see if there are traces of wear after use at the needle corner of the lower broadcast port.
If you are afraid of repairing (mostly referring to repairing bad sectors), then check the capacity of the hard disk (column, fan) after booting it and compare it with the data of the relevant model of hard disk published on the Internet

Anonymous users2024-02-06RAID means that you have a RAID controller (which can be an external card) on your motherboard, which can combine multiple hard disks into a whole column of disks. For hard disks, it doesn't need to know the details of RAID, it just needs to do the function of reading and writing data on its own hard disk, so it can be considered that all hard disks support RAID

Anonymous users2024-02-05How to say, all hard disks can support RAID, RAID is the concept of disk array, if you buy a general IDE or SATA interface of the hard disk, through the RAID card to enjoy the array combination, if you buy SICI can be the array itself, you have to figure out the concept of RAID first, RAID is a rework? The first time you heard about it, you can go to the web and search for information about raid, and you'll find out.

Anonymous users2024-02-031.How to tell if a computer has a raid installed:
1).Restart the computer, during the boot process of the computer, if there is a RAID card, the RAID ROM will be loaded, and there will be prompts similar to "Ctrl+A", "Ctrl+H" during the loading process.
2).Enter the operating system, if you can see RAID and SCSI devices in the device manager, if there is a RAID card, it means that the system is very likely to get RAID.
3).There is also soft RAID, which is achieved through the operating system, which can be seen directly through the operating system. If it's linux, it depends on whether there is a dev md0 or something like that.
If it's Windows, go to Disk Manager and you'll see it.
2.How to determine the raid type of your computer:
1) If it is a soft RAID, right-click on my computer, then click Manage, and then click Disk Manager, you can find it inside.
2) If you have a RAID card, you have to follow the corresponding procedures to see it. For example, RAID management software such as HP and Dell.

Anonymous users2024-02-02Chinese means independent redundant disk array.
RAID is an abbreviation that means independent redundant disk array in Chinese. Redundant disk array technology was born in 1987 and was proposed by the University of California, Berkeley.
To put it simply, it is to combine N hard disks into hardware and software through the raidcontroller into a virtual single large-capacity hard disk. The use of RAID brings significant benefits to the storage system or server's built-in storage, with increased transfer rates and fault-tolerant features being the biggest benefits.
Features of RAID:
1. The storage capacity is expanded, and the storage space with huge capacity can be composed of multiple hard disks, which reduces the cost of unit capacity, and the largest capacity of hard disks on the market per trillion capacity is much higher than that of popular hard disks, so the unit of the array composed of multiple popular hard disks is much lower.
2. Improve the storage speedThe increase in the speed of a single hard disk is limited by the technical conditions of each period, and it is often very difficult to go further, while the use of RAID can allow multiple hard disks to share the read or write operation of data at the same time, so the overall speed has been doubled. Reliability: RAID systems can use two sets of hard disks to synchronize mirrored storage, which is the most important security measure for a network server.

Anonymous users2024-01-31The problem of the server not detecting the hard disk can be related to the RAID because RAID usually requires the RAID information to be set on the hard disk, and if the RAID information is corrupted or lost, it may cause the server to not detect the hard disk. Specifically, there are several reasons why a hard drive may not be detected by the server:
RAID Card Issues: If the server is using a hardware RAID card, then the problem may be with the RAID card. For example, a corrupted RAID card, improper installation, incorrect settings, etc., can cause the hard drive to go undetected.
Hard drive connection issues: If the hard drive is not connected correctly, it can also cause the server to be unable to detect the hard drive. For example, a sas-sata cable that is not securely connected, a connector that falls off, etc., may cause the drive to remain undetectable.
RAID code bridging problem: If RAID information is corrupted or lost, the server will not be able to detect the hard disk. For example, RAID information is mistakenly deleted, corrupted, or the disk data is incorrect, which may cause the hard disk to fail to be detected.
So, if the server can't detect the hard drive, you can check that the hard drive is connected correctly and then check if there is a problem with the RAID card and RAID information. This can be detected and repaired by checking the server's BIOS settings or by using the relevant tools. If the problem cannot be solved, it is recommended to contact the manufacturer's technical support for further diagnosis and treatment.

Anonymous users2024-01-30If the server is unable to detect the hard drive, it may be related to the RAID settings. RAID is a data storage technology used to store data on multiple disk drives to provide greater fault tolerance and reliability. Typically, hard drives installed on servers are configured in RAID mode to improve performance and reliability.
If the server is unable to detect the hard drive, it may be due to a failed RAID controller, a corrupted hard drive, or a misconfigured RAID device. In this kind of spine situation, it is advisable to check the RAID settings of the server and make sure that both the hard drive and the RAID controller are in working order. If the problem persists, you may need to dig deeper into the problem with the server hardware and software. Nothing.
According to experts from Changsha Dongda Anorectal Hospital, hemorrhoids attacks are a common phenomenon in life, but common does not mean that there is no misdiagnosis. Click to enter**Expert consultation》 The South Korean drcamscope anorectal examination system of Changsha Dongda Anorectal Hospital adopts the sixth generation of visual medical ** and imaging technology, which can clearly observe the lesion site magnified dozens of times, and can also collect images of the deep lesion site inside the anorectum to understand the condition clearly and accurately; Avoid misdiagnosis and mistreatment, help patients choose the best plan, and avoid delays caused by the shortcomings of traditional human examinations. At the same time, the lesion can be locked and printed for imaging, which provides a reliable basis for comparison before and after. >>>More
A fracture is an injury in which the integrity or continuity of bone or cartilage is disrupted.
