The hard disk of the industrial computer stores a large amount of work data we need. Once damaged, it will have a great impact on our work. Therefore, our technicians need to take some special protection measures for the hard disk of the industrial computer when operating the industrial computer. However, Even so, the disk of the industrial computer still fails. As a well-known industrial computer supplier in China, Netcom Technology will discuss with readers how to take remedial measures before the failure occurs. Readers are advised to learn to use GHOST (disk cloning software) software, and the object version is as up-to-date as possible, which will help the implementation of the following programs.
No capital investment solution: GHOST clone image.
Premise of the solution: only if the system disk fails, the system disk can be formatted normally by FORMAT software. (The author has encountered twice that the system disk cannot be formatted with FORMAT software normally. In the master-slave disk mode, when accessing the system disk of the bad disk, the parameter error is prompted, and the low format is used to restore it.)
Program materials: GHOST software, DOS system boot disk (CD, software, U disk)
Solution implementation: Most disk failures occur in the system disk (C disk). After the automation system is officially put into operation, first use the GHOST software to mirror the system disk, and put the image file (*.GHO) in the FAT32 disk format for backup (Because in the case of a single disk, GHOST recovery of the system disk is generally performed under DOS. DOS can only run under disk formats such as FAT32 and FAT16, and cannot be run under the NTFS partition format.), once the system If the disk fails, the fastest way is to format the system disk, and use the GHOST software to restore the original mirrored files to the system disk in about 5 minutes.
Solution conclusion: No equipment investment, no capital expenditure; fast recovery. This solution can only be used when the operating system is damaged and not when the disk is physically damaged; once the disk is physically damaged, this solution will not work. This can also be extended to whole disk mirroring.
Economical solution: clone dual hard disk backup + GHOST image
Premise of the scheme: IPC disk failure (whether it is a system failure or a physical disk damage)
Program materials: a disk of the same type in the target industrial computer, GHOST software, DOS system boot disk (CD, software, USB disk)
Solution implementation: Before the industrial computer system is put into operation, use the GHOST software to first mirror the system disk (C disk) containing the control system disk to the non-system disk FAT32 disk format partition of the disk, and then clone the entire hard disk content completely. to a spare disk of the same type. Once the operating system is damaged, the image file of the operating system can be restored; if the entire disk fails, the bad disk can be removed and replaced with a spare hard disk with the same content backed up first.
Solution conclusion: only need to invest a disk (about 400-800 RMB, depending on the size of the disk and the manufacturer), easy to replace, fast recovery, and can eliminate all disk problems.
Security investment plan (economical): software disk array using Windows 2000 dual hard disk RAID1 or three hard disk RAID5 mode
Premise of the scheme: The implementation time of this scheme is better before the industrial computer is put into operation
Program materials: Windows 2000 system disk or later, two disks (the same model is appropriate)
Solution implementation: First install Windows 2000 system or later (because Microsoft is better for disk arrays after Windows NT), and enable disk array function support. The disk array method can write the same content to two disks at the same time when the industrial computer is running. If one of the two disks fails, the other disk can write the same content at the same time without disturbance. Switch to normal working state. That is to say, as long as one of the two hard disks in the disk array mode is not damaged, important data will not be lost. The bad disk can be replaced or repaired afterwards. The bigger advantage is that it will not affect the loss of production data, and the replacement speed is also very fast.
Conclusion of the scheme: The investment is small, the security is high, and the stability is related to the quality of the system installation, but it is not easy for beginners to master the technology.
Security investment plan (stable): use low-end server hardware disk array (used in places with low technical requirements, high stable production, and important data)
Project materials: A low-end server that supports hardware disk array function is about 25,000 yuan
Solution implementation: Because it is a hard disk array, all external interference to it is low, and the failure rate is low. In the event of a disk failure, it is only necessary to remove the bad hard disk and replace it with a new hard disk of the same type. For specific implementation methods, please consult your low-end server provider for details.
Conclusion of the scheme: relatively large investment, high security, good stability, and low technical requirements.
The harm caused by the failure of the industrial computer disk is self-evident. Ensuring its safety is a problem that our industrial control personnel should pay attention to. Only if we take detailed protective measures in advance, the industrial computer can run stably and efficiently. The author adopts the above method in actual work, which effectively avoids the disk failure of the industrial computer, and can shorten the repair time of the failure from the original several hours to a few minutes, providing guarantee for normal production. The author's level is limited, and I hope readers will not be stingy to correct the mistakes and deficiencies.
