GHOST abnormal situation analysis

                  GHOST is the most commonly used and most powerful tool software in the backup/maintenance system. Its usage and instructions have been introduced in many articles. Here I intend to list some abnormal situations in the use of GHOST, for those who encounter difficulties. diseases friends reminder:

First, the exceptions list and analysis

1, GHOST get more than one backup file

strictly speaking, this is not abnormal situation, However, many people backup systems are backed up to 2G system area into GHO files, in order to save time to reinstall windows system; or use disk-to-disk method to mirror the entire disk to another hard disk, rarely more than a few G The partitioning of data is made into a file placed in the same partition of the hard disk (because there is no special meaning in security, it is in the same hard disk). So encountering this situation may be overwhelming. This is caused by the limitations of the operating system, mainly because DOS does not support large files:

The first time I found GHOST, the so-called "abnormal" is when I make a backup on a friend's machine. He said that it is very troublesome to have a backup, ask me for help. I went there and tried it. The situation is this: a hard disk is divided into C drive 5G, D drive 10G, E drive 14.3G, and the partition format is FAT32. C disk used space is 2.8G, use GHOST to do C backup, select partition to the image file, when done more than 90%, jump out of the dialog box warning prompt, can only choose OK, otherwise stop; after reading, there are 2 Documents: 1.GHO and 10000001.GHS [Note: 1. GHO is the file name taken].

I made a backup of the C drive of three machines. Only one C drive has been successfully used for 1.8G. 1.GHO, only one file. In addition, the two used C disks have been converted into two files with 2.8G and 2.5G. GHOST6.0 and GHOST2002 have tried, the same situation. I first suspected that there might be a disk error, so I first ran the scan disk to correct the error, and defragmented with VPOT, then GHOST, and met the same situation. The details are as follows:

C disk 5G (FAT32), used space 2.18G, when more than 90%, display

"INSERT NEXT MEDIA AND PRESS ENTER TO CONTINUE..."

Is there OK/CANCEL/FILENAME? Three options. Select FILENAME, named 2.GHO (1.GHO can not take the prompt to cover). When it continues to about 98%, the screen displays "RE_INSERT1ST PORTION OFIMAGE", which can only be completed by 1.GHO. At the time, I was wondering why GHSOT would not be able to handle files larger than 2G. I thought about it for a long time, and suddenly found out that he switched from DOS screen to windows graphical interface on another machine. As soon as I arrived at his home, his machine was already open, and it was a DOS interface. I did not think about running the GHOST program. These are all running under the pure DOS interface. The files obtained by GHOST in the pure DOS state are indeed subject to The limit of the number of bytes, a single file can not exceed 2G, and in the windows DOS window, everything is based on the windows kernel, more than 20G is no problem.

2, after GHOST some partitions can not be accessed under DOS, that is, windows98 DOS window or graphical interface can access the partition normally, but in pure DOS can only access the previous several partitions The last one or several partition prompts are illegal drive letters and cannot be accessed. In addition, there is also the use of ghost7.0 to clone win2000. The cloned system always prompts no page file or the page file is too small to run when it is started for the first time. These are mostly because the profit-taking map is convenient when installing the machine, directly find a clone file on the hard disk or CD on the original machine, GHOST data to the new machine, because the model and capacity of the hard disk and the settings of windows2K The difference has caused certain compatibility issues.

3, this is the real GHOST abnormal fault: in a friend's dual hard disk system machine, the second hard disk 40G, one of the partitions is more than 20G, found that after running GHOST, can not Identify large partitions over 20G. In the GHOST software, it shows that the large partition is actually the remaining unformatted disk space, marked as *FREE, which is still normal, but if you continue to operate, the partition will crash. I carefully looked at the settings in his CMOS and found that the BIOS of this motherboard can only recognize the first 10G hard disk, can not identify the second large hard disk more than 32G, and he is not willing to load the special large hard disk management provided by the manufacturer. Tools, the second hard disk is set to NONE, can only be recognized by windows98, although running software, playing games are no problem, but want to use GHOST but not. This double hard disk failure situation should be encountered by many people. The large hard disk can not be recognized by the motherboard's BIOS is a typical tricky problem, plus dual hard drive + GHOST, is a bit of a headache.

Second, the corresponding solution

1, for the first case, in fact, is normal, but only a little less. When GHOST restores the image, it can automatically find the second GHO file to continue recovery. If you want a single file, you can use the DOS COPY command, plus the binary copy of the parameters to synthesize a separate file, be sure to add binary parameters, otherwise you get a mess. The instructions are as follows: Execute the "Copy/bfile1+file2+...outfile command, outfile is the name of the file you want to get, you can name it yourself. By the way, if you are merging text, you don't need binary /b parameter instructions. /This article comes from the computer software and hardware application network www.45it.com

2, GHOST is indeed a very rigid mirror program, this can not be behind the pure DOS recognition In the case of several partitions, please try to repair with the windows installer first. If it doesn't work, it is better to format the C partition and reinstall the system. Pay attention to the hard drive or patch of the motherboard so that the system can correctly identify the hard disk. Manufacturer model, use DMA or ULTRADMA function. If you can't solve it, please backup the data and re-partition.

3, this is caused by the motherboard's BIOS is too old, can refresh the BIOS is best, so sure Directly manage the hard disk, run GHOST backup normally. If you can't find the new BIOS, there are two ways, one is more troublesome, get another machine, change the capacity of the partition to less than 10G, GHOST can Second, use DM universal version and other tools to manage the hard disk. But after using DM, the system must load the hard disk management program before loading windows, which is a bit inconvenient. I really don't want to use DM and other tools, but also want to back up windows. Finally, here is a compromise: use ZIP or RARforwindows (must be the windows version, otherwise the long file name will be destroyed). The entire windows directory is compressed and backed up into a file, preferably automatically decompressed. First delete the directory tree where the original windows is located, and then extract it.

This compromise backup method has two shortcomings: First, you are required to have dual systems, such as windows98+windows2000, then in one out When the problem occurs, you can use another one to extract the recovery. If there is only one windows operating system, or two windows at the same time, then you can't do anything, because Windows 瘫痪 self-extracting programs can not run under DOS; the second is this The backup recovery method is invalid when the boot area of ​​the C drive is destroyed. It is not as good as the GHOST. Yee install windows partition or not too good, 3 ~ 5G is more appropriate value.
