Solutions to server hard disk failures;
The first case: first check whether there is a physical bad track on the hard disk, and check it with the software HD tune. If there is a physical bad track, it is very practical and it is recommended to replace it.
In the second case, if the hard disk is lost due to illegal shutdown, you will be prompted to run the chkdsk tool to repair it, which means that the contents of the hard disk can still be restored.
It is very simple to repair the file loss caused by illegal shutdown with chkdsk tool. Click Run on the menu bar at the beginning, and then enter cmd command to bring up dos. Then enter chkdsk:h /f h to indicate that there is a space after your drive letter /f to fix the error on the disk. Then you will see the prompt shown in the figure below. You can choose Y, and then you can restart after checking.
If you think there is another simple operation method for the above faults, directly click the right-click property of your hard disk, check the errors, check the two boxes, and restart after the check is completed.
Maintenance and management of extra server hard disk;
1, using RAID technology to enhance the fault tolerance of server disks, what is RAID? Redundant array of independent disks? The abbreviation of "Independent Redundant Disk Array" in Chinese means "Independent Redundant Disk Array". Simply put, it is to improve performance and fault tolerance by organizing multiple hard disks into a disk array. For example, Raid 1, Raid5 and other arrays allow one hard disk in the hard disk array group to make an error without data loss. Although the initial investment will be increased, I think it is worthwhile to use Raid technology to enhance the security of server hard disk maintenance.
2. In addition to Raid hard disk fault tolerance, some very important data should be backed up by other devices from time to time. It is suggested that the network server based on enterprise users and commercial users should choose tape drives and professional backup software (Veritas Netbackup, CA Arcserver) to make a relatively perfect backup plan regularly. If you are an individual user, it is recommended to use an economical CD-ROM/DVD as the backup method. 3. For some simple accidental deletion or formatting, in the case of few files and good personal skills, you can download some recovery software (data recover, easy recover, etc.) for server hard disk maintenance. ) try to save it online. Of course, you can make a complete backup of the disk with Ghost software before you do it, and it is best to pick it up from the disk when you restore it. Of course, if you are not satisfied with the results of personal recovery, you need to seek a professional data recovery company to operate.
4. If you find that the server data is lost, don't operate blindly to reduce the probability of data recovery. You can find formal technical support of data recovery company by phone, listen to proprietary advice or ask professional technicians to check. At this point, you can turn off the server hard disk to stop reading and writing data. No longer write data to the partition or hard disk that lost data. Reduce secondary injuries. 5. Always pay attention to the operation and maintenance of the server hard disk and observe the indicator light of the server hard disk. Generally speaking, the appearance of the server has an indicator light on each hard disk, which is usually green. When the indicator light appears in special circumstances, it is necessary to take relevant measures to carefully check whether the hard disk device is normal. Once the hard disk is damaged or data is lost, please don't be surprised and lie, and be sure to keep a cool head. The following are common computer hard disk failures and suggested measures for users:
Emergency measures for server hard disk maintenance in case of hard disk damage or data loss;
1, the hard disk has abnormal sound, and the magnetic head is not addressed correctly at this time. In order to prevent damage to the disk body, it is necessary to cut off the power supply immediately, and do not disassemble the hard disk. A professional company with a clean room is needed for disassembly inspection.
2. The 2.BIOS does not recognize the disk and cannot find the hard disk. Please have the computer engineer check it carefully first. You need to inform that there are important data in it first, and you need to handle the maintenance of the server hard disk carefully. So as to avoid hard disk damage caused by misoperation again. 3, the hard disk is normal but suddenly unable to read data:
Do not perform operations that will destroy data, such as rebuilding partition tables or formatting. Although it can still be saved, 100% cannot save all the data. If it is damaged, it will not be worth the loss.
Make a correct judgment first, and don't reinstall the Windows operating system or use the recovery disk to maintain the server hard disk. Covering the data area is easy, usually covering several hundred meters.
When starting up, if Scandisk and Vrepair are automatically executed, please press Esc or spacebar to cancel the action, and check the cause of damage first to avoid a large number of internal files being damaged. 4. Of course, if it is confirmed that there is a special fault in the maintenance of the server hard disk, it will be opened! It is very important to choose a professional data recovery company at this time. Because of the high technical threshold, data recovery is less than that of ordinary computer maintenance companies, but less does not mean no, some JSs with poor technical strength and limited environment, and even JSs that only take orders and then transfer to other companies can be seen everywhere.
At this time, please need to identify carefully. Avoid being deceived, resulting in incalculable late losses.
