can I change my hard disk serial number????? and if I can , what's the way??? | ||

Sorry, the serial number the manufacturer built into the hard disk cannot be changed using WinHex, only the volume serial number of a logical drive, which is stored in the boot sector. | ||

hi all ------ how can i read the physical hard disk serial not logical thnx for ur time | ||
| Stefan Fleischmann (Admin) |
Under Windows 2000/XP, Windows is already able to display the serial number under certain conditions (in the details panel). The next WinHex version is supposed to be able to do that principally. | ||

thnx Stefan.. i want to read it manual..if it possible to know the starting address of serial..i will be more grateful for u thnx again | ||

As far as I know, it is not stored in a certain sector of the hard disk. | ||

can we say that, serial may existed in ROM of hard disk...so can ur program read this | ||
| Stefan Fleischmann (Admin) |
No, it can't, it asks the operating system. | ||
| Heggooo (Heggooo) |
ok, but how..it must be existed in hard disk and OS use system call to read it | ||

i want to know how 2 find cpu, hard disk (not volume serial number), ethernet card serial numbers using my own programme in c or assembly language, on linux,windows, unix machines ? | ||
| hassan |
can i change the volume serial number of a logical drive which is changed every format can i chnge it without format | ||
| Stefan Fleischmann (Admin) |
Yes, e.g. using the boot sector template in WinHex. | ||

I have a software that lack on the Hard disk serial number, which make it difficult to re-install software into another computer with different Hard disk. Is there ways to work around it? Since Hard Disk serial number cannot be modified. | ||

The way to extract the physical serial number of the hard disk is to use the ATA command set and use command ECh (Identify Device) then extract the serial number from the buffer. In order to do this you would need a Port IO driver that works under windows without crashing. The main problem is that Windows intercepts direct IO commands particulary where it has already remapped the port to use it's own drivers. Direct ATA commands sent to the drive through windows usually blue screen or freeze the system. In order to change the serial number you would require the secret 'factory' ATA commands to read in the serial number module. Changing it can result with a non working drive. There are at least two explanations. Most manufacturers use a single 512 byte module for the serial number, however they also contain a checksum at the end of the module, so when changing the serial number you would need to recalulate the checksum and then write the module back to the drive - again requiring factory or reserved command sets. Drives with invalid checksums may not operate correctly or at all. Some software houses use port remapping in order to lock software to a specific drive, however many just use the logical serial number field in the boot sector. The second reason is that some manufacturers (e.g. Quantum) use parts of the serial number to identify for example, the number of physical heads on the drive. So changing the serial number could change the head count and result with a dead drive. There are some tools you could try, such as the NTPort and MemAccess dlls. Search and you will find  Both require an understanding of computer ports, registers, etc.. Mike | ||

I should have mentioned ... Changing the logical serial number may disable any software that is already locked to the original serial number .. Take care! Mike | ||

I can change hdd serial number. I have problem with software that protected by serial number, i want to backup the software to other hdd but the software can not run in the other hdd. To resolve this problem i found the software from http://slayo.com exactly http://slayo.com/harddisk-volume-serial-number-changer.html |
