The hard disk is a very important part of the touch pos cash register. All data and data are automatically stored in the hard disk. Once the hard disk is wrong, sometimes the data loss will be greater than the loss of the entire POS cash register touch cash register. However, as one of the hardware of the POS touch cash register, most people always think that the hard disk is not easy to damage. If it is broken, it can't be started. Some people think that the bad track is easy to identify, and find out what kind of disk doctor is used. The software repair will do, and then it will be low! In fact, the bad sectors of the hard disk, can almost be called the fatal injury of the hard disk. The user has seen a lot of examples of delaying the time, using various software repairs, and finally smashing a large hard disk into a piece of scrap iron. Repair pos touch cash register hard drive bad track For the logical bad sectors of the pos cash register hard disk, we can fix it. For the physical bad sectors, we should adopt the isolation method to minimize the loss and prevent the bad channel from further spreading. I have seen some people in the newspapers whispering that they can repair physical bad sectors with a special software. The most terrible thing is that many people are superstitious about low-level hard drives. It is really a mistake. The so-called low-level formatting refers to dividing a blank disk into a cylinder and a track, and then dividing the track into a plurality of sectors, and each sector is further divided into an identification part ID, a space area GAP, and a data area DATA. Low-level formatting can only be done in a DOS environment, and can only be used for a block hard drive and cannot support a separate partition. Some bad tracks and bad sectors can be repaired by low-level formatting, but the physical scratch on the surface of the real hard disk can not be repaired. This only marks the location of bad sectors by various methods, so that the operating system does not go. Use to prevent the expansion of bad sectors and thus extend the use of the hard disk. In particular, it is emphasized that low-level formatting is a lossy operation that has a certain negative impact on the life of the hard disk. Therefore, if it is not necessary, users should try not to format the hard disk in a low-level manner. For logical bad sectors, we can usually find and fix them with the tools that come with the operating system and some special hard disk check tools. For example, the Scandisk disk scanner that comes with Windows is the most commonly used tool to find the bad sectors of the hard disk. Our common Format command can't fix any bad sectors on the hard disk. We must understand this. In the Windows system environment, in the "My Computer", select the hard drive letter to be processed, select its "Properties", select "Error Status" in the "Tools" button that appears, and then in the "Scan Type" Select "Comprehensive Inspection" and put "Automatically Fix Error" on the "Check" and then "Start". If the system does not scan the disk at boot time or can not enter the Windows system, we can also use the floppy disk or CD-ROM boot disk to start the computer, under the corresponding drive letter, such as "A:" run Scandisk*: (Note: * is The hard drive letter to be scanned), and then press the car to repair the hard disk partition that needs to be scanned and repaired. However, if pos touches the physical bad sectors of the cash register hard disk, then don't try to use these methods to repair. On the contrary, repeated scanning with various tools is to force multiple reading and writing of the physical bad area of ​​the hard disk. Inevitably, the bad sectors will be increased and spread. The correct method is to use the following method to decisively isolate the existing bad sectors. This is a very helpless approach, such as a 20G hard drive, if the 15G is blocked due to bad sectors, there is always 5G space available. If you don't do this, the final result is that the entire hard drive is completely scrapped. Method 1: Work with disk software such as PartitionMagic For example, PartitionMagic partition software, first use the "check" command in PartitionMagic4 or the disk scanner in Windows to scan the disk, calculate the location of the bad cluster on the hard disk, and then select "Advanced/badSectorRetest" in the Operation menu, the bad cluster is located After the hard disk is divided into multiple zones, the partition where the bad cluster is located is hidden to avoid misoperation in Windows. This function is implemented by the HidePartition menu item. This also ensures the normal use of hard disks with serious bad sectors, and eliminates the system to frequently read and write bad sectors to expand the area of ​​bad sectors. But this requires familiarity with these softwares, and the experience of computing hard drives, many people are not easy to be accurate. Method 2: Use FDISK and the format command FORMAT The specific method is this. The first thing to do is to find out the capacity of the POS touch cash register hard disk. For the problematic disk, use FDISK to divide it into a C disk, then format it with FORMAT, and when it encounters a bad block that cannot be repaired. Always try to fix FORMAT, then record the percentage done. Then press CTRL+BREAK to force the task to terminate, use the total disk capacity × percentage to get the normal disk capacity, use FIDSK to draw a logical disk, and then The latter disk estimates the approximate size of the bad track, which is about 10%, and then divides a logical disk. This small disc is not formatted, it is deleted after the total work is completed, so that the bad blocks are all skipped. This may lose some good things, but it is not important for large-capacity hard drives, and hard drives are more stable. Method 3: Use a special bad disk partitioning tool such as FBDISK FBDISK This is a DOS software or PE system that specifically discovers bad sectors and re-partitions after isolation. There is only one file, only a few tens of K. The operation is very simple. First make a floppy disk that can boot to DOS, put FBDISK on the floppy disk, use it to boot the system, pay attention to the system can only hang a hard disk to be repaired, and connect it to the line of the main hard disk. After entering DOS, as long as you can find the hard disk, run FBDISK. This small program will scan the hard disk according to the track, and find that the bad track is displayed. It also estimates how long it takes to scan the whole scan. After that, the program will propose a new partitioning scheme based on the scan results and bad sectors. If you accept it, press Y, otherwise your hard disk will not be processed. This software is good, but it may be a big hand. I once used it to scan a 10G hard disk and reported that only 300M can be used, but after using Method 2, I found a good space of nearly 2G. So everyone is still on demand, for non-professionals can contact the cash register manufacturer.
