On the Unix system with Ghost clone

use ghost This question is not very easy to answer, everyone has returned enough posts, but some places are still not comprehensive, because everyone is not the same situation. Basically,

1)4 G The following copy must be strictly matched; some hard disks can be modified by the hard disk parameters in the bios to reach the large disk copy

2) 4G or more, without limiting the size of the disk As long as the target disk can put down the unix partition

but pay attention to the following points:

A) The machine's BIOS must identify the hard disk parameters; some machines (such as HP's Brio, CompaQ's D5xxx, etc.) The hard disk algorithms used are different. If they are interchanged on ordinary machine hard disks, they cannot be booted. So their disk can't be copied with the disk on the ordinary machine;

B) The boot file system inside the unix partition must be guaranteed in the first 8G of the hard disk (of course, if the unix partition is all In the first 8g, there must be no problem.)

C) It must be ensured that the starting position of the unix partition is 0; the starting cylinder is 1, otherwise it will not be able to boot in most cases (remember that there is a partition in Unix) Suggestions, plus the number of sectors as the start of Unix?); the reason for this situation, most of the use of ghost, ghost adjust the partition, in order to be safe, you can first use the tools such as diskman to divide the Unix area And then copy; or, if you use the same hard disk, simply open the sector copy parameters in the ghost, so that you can use

D) according to the experience of data recovery, especially recommended not to The Unix partition is placed at the beginning of the entire hard disk. The reason is that many viruses like it here. They can't correctly identify Unix. The result is that Unix is ​​completely over; if you can modify the partition pointer in the back, you can save Unix

E) used to copy The machine, bios must correctly support the capacity of the hard disk; for example, some old bios will have problems in identifying more than 9G, and copy out can not be used;

3) The mutual copying of scsi and ide is exactly the same, completely Can copy each other, do a few core spares; if you modify the parameters, you can make a system that is common to scsi and ide; however, the machine used for copying must correctly identify the capacity of the hard disk (even if scsi is copied; if the machine Can not identify the same capacity of ide, there will be problems)

In general, almost 70% of the time, without any prior knowledge of the preparation can be copied successfully; the remaining 30%, is discussed above The edge is wrong.
