Disk Signature Collision While Cloning
Microsoft Windows has been sending out updates which have created some problems for those cloning mass storage devices like USB flash drives and USB hard drives. This article should help you resolve those issues.
The Disk Signature is a unique ID Windows will assign to a device inside the Master Boot Record or MBR. The disk signature is 6 bytes long and sits in the first sector of the mass storage device. The disk signature becomes a problem for those cloning flash drives or hard drives with either a software utility or a large duplication equipment like a USB duplicator. The disk signature compounds itself if a multi-partition device is being cloned.
Many times a multi-partition device is created in Linux and at the time of create only one disk signature is assigned to the physical device. However, if multiple units of those copies are put in a Windows computer, Windows will try and assign a disk signature to each partition. This will cause a collision.
There are different situations one could have a disk signature collision, so this is only one example.
GetUSB.info did a write up about this a couple months back, here is the full blog post:
In addition, we found the following website which does a fantastic job about how one would edit the disk signature using a hex editor:
