#How to clone disk with macrium reflect free serial number

So, those programs might have recognized that the hardware serial number or model info indicates that you are using different drive, requiring reactivation even if the clone was an exact replica of the disk platter contents. That's not the same thing as the volume IDs/serial numbers on disk. Those can make an exact copy of a drive, including the MBR and Partition table.Д«ut, even with an exact copy, the programs you had issues with may be looking at the drive model and serial number of the drive in the drive's EEPROM, as malch mentioned in his first post to this thread. Personally, I use either dd or ddrescue (linux utilities) to perform sector by sector copies (including unused space). But, i guess that some vendors are picky about any changes at all. They should be able to tell it's the same computer and just has a different drive in it, and should not care about someone replacing it. I don't know why those programs would care.

So, if you told it to do that, perhaps some of your programs didn't like it, even if the volume IDs are the same on the cloned drive.ДЄ true sector by sector clone would have left the partition sizes the same (meaning you'd have unallocated space at the end of the larger target drive), if the cloning software was leaving the boot loader and partition table (first 512 bytes on drive) intact.Д«ut, if you told Macrium to fill in the rest of the drive space by making the last partition larger, it may have made a sector by sector copy of the original, then performed a partition resize and update of the partition table meaning the software you're using may not have liked that difference. I see where Macrium has a wizard that lets you do that kind of thing when cloning. If not, then the cloning software probably resized the last partition larger and updated the partition table to reflect that change.

Now back to trying to find why my 2002 Jaguar x308 won't start.Дid the target drive (larger than the original) end up with unallocated (unpartitioned) space on it at the end? I will watch this closely in making regular clones (as W7 backups). It is only a couple apps that were affected. In my case the the cloned W7 HDD boots up fine. I tried finding how apps may be affected, no joy Seems to me that disk signature collision affects booting of the OS. However, on the off chance you attach a cloned disk to a Windows system that has a disk with the same signature, you will suffer the consequences of disk signature collision, which renders unbootable any of the diskвЂ™s installations of Windows Vista and newer. This signature dates back to Windows NT 3.5 in the mid 1990s and was then referred to as the Fault Tolerance Signature because its primary purpose was to help a booting or booted operating system uniquely identify individual hard drives in a fault tolerant dynamic disk raid configuration. The Disk Signature is a unique ID number that Windows writes to a specific location inside the Master Boot Record ( MBR) on the first sector of every hard drive that it sees.

This article is for those who have received an error message from Windows 7 saying 'This disk is offline because it has a signature collision with another disk'.

Yes, that is what my life has been missing, not knowing about disk signature collision!!! Sooo, I googled 'disk signature' and found a lot about 'disk signature collision'.
