For the novice to bluff: see the trick of the liar 1G hard drive to become 120G

During the process of repairing the computer to the customer, I often encountered the situation that the hard disk capacity of the customer's computer has been modified! These computers are undoubtedly purchased at low prices on the roadside or online. The so-called P4 computer is just MMX. 512M of memory is 16M, 120G hard drive is 1G or less, and it is regrettable to be late! There are two common methods for making fake hard drives:

1: Copy partitions. With the DOS external command SUBST in WINDOWS, SUBST is a virtual floppy disk command. Example: Take SCSI9.1G to 20G as an example. First, divide the C drive to 3.5G. After formatting, reinstall the system, and leave the D drive. Then create a subdirectory E.F on the D drive and hide the subdirectory E.F. Finally edit the AUTOEXEC.BAT automatic batch file, add the following two lines of commands (SUBST space E: space D: E) (SUBST space F: space D: F). Note: The scammer joins in the first line (@ECHO space OFF). People can't see what command he is running. After rebooting, there are four zones in the system. Friends who are familiar with DOS commands will be more clear.

2: The partition table error. You can use ordinary partitioning tools. The scammers generally use SFDISK, but they don't have to be in one step. Sometimes they have to try many times. Be sure to install the system first, and then expand the partition! Example: Take SCSI9.1G to 20G as an example. First, the C drive is formatted for 4.5G, and the system is installed (the remaining space is divided first, so keep it). Install the system, run the partition tool SFDISK under DOS, divide the partition: D disk is divided into 100M, and the rest is given to the E disk (note that the D disk is not formatted, only the E disk can be formatted), restart, the system is also four District. Sometimes it is not a success, you have to try a few more times to divide the extended partition. If you want to divide into 30G, you will have one more 100M partition without formatting in the middle. Why use SCSI hard drives, because SCSI does not see parameters in CMOS. You can also do it with the IDE disk. First insert a 40G into the CMOS and confirm the parameters and store them. Then plug in a 10G and don't recognize the parameters. You can format the partitions again, all 40G, but in a system. 10 more. If the scammers combine the above methods, then people will become 40G without knowing it. Haha! The first method, E.F disk can not be scanned in the system. In the second method, each disk can be scanned in the system. In addition, in the system properties, the scammer also used the software to modify the CPU and memory parameters. Generally, the rookie can't see it! The cracking method is very simple, just format the hard disk.
