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:

Press Release: Nexcopy Introduces Default State USB Write Protection Flash Drive – Lock License

“The fundamental change towards how our flash drive works should draw attention for those looking for read-only USB flash drives” says Greg Morris, CEO of Nexcopy Inc.

What is unique about the Lock License approach is whenever power is cut to the device, for example disconnection, the USB is automatically write protected. This is the strongest first line defense against malicious software or virus jumping onto a flash drive without the user knowing. It is impossible to infect a USB drive if the device is write protected.

Lock License flash drives require a password upon first use. This password is used to unlock the write protection and make the USB a read/write device. This feature provides a personalized solution for each business which uses the Lock License technology. There is no need to set the write protection after being unlocked because simply cutting power to the device will put the USB into its default state: A read-only device.

The Nexcopy Lock License USB flash drive has the following features:

  • Default state of drive is read-only, a.k.a write protected
  • User assigned password to remove write protection
  • No password is required to read from the drive, acts as normal WORM device
  • Graphical User Interface (GUI) to set password and remove write protection
  • Command line utility for custom integration to remove write protection
  • No back door password or feature from Nexcopy to unlock the drive
  • Available in USB 2.0 and 3.0 technology and ranging from 2GB through 128GB capacities

Stan McCrosky, head of Sales, comments, “System Control manufacturers for waterworks, electrical utility and petroleum companies need a solution like this. The ability to load software or firmware to a hardware based USB read-only device gives system control companies an incredible amount of security for in-field deployment via USB. More importantly, the command line utility gives the manufacturers a secure way to unlock the drive and update the content remotely without the worry of the drive remaining read/write. It’s simply impossible for the drive to remain writable.” McCrosky concludes.

The Lock License USB flash drive is simple to implement. Steps include:

  • Connect USB to a Windows computer
  • Open either GUI or command line utility to remove write protection
  • Assign a password to be used when removing the write protection
  • Data load the drive as needed
  • Eject drive from computer once copy process is complete
  • At this point the USB is write protected at the hardware controller level
  • The Lock License drive can be read (used) by any device on any platform
  • Password not required to read data from the drive
  • Password is only used when removing write protection to make the USB read/write

Nexcopy Lock License media is available in USB 2.0 and USB 3.0 technology and range it capacity from 2GB through 128GB. Nexcopy offers six body styles for the Lock License media with a wide range of body colors available for each stye, all available for custom branding. The six body styles include Oxford; a capless swivel style drive. Newport; a classic rectangular shape with cap. Lexington; a classic rectangular style with rounded edges and cap. Augusta; a shorter style drive with large lanyard loop. Huntington and Geneva which uses an aluminum body for more durability and also better suited for laser etch branding.

The Oxford style swivel drive is the in stock media Nexcopy carries for same day printing and shipping. Nexcopy inventories USB 2.0 media of 2GB and 4GB capacity and in stock USB 3.0 media of 8GB, 16GB, 32Gb, 64GB and 128GB capacities. The in stock Oxford media is a black body with white swivel clip with full color printing via the Nexcopy Logo-EZ USB flash drive printer.

The Lock License utility is available for download off the Nexcopy support page. The utility requires a Nexcopy licensed USB flash drive. The Lock License USB write protection is not a universal solution for any thumb drive, a Nexcopy drive is required in order to take advantage of the increased security the technology offers.

Home Office Tools – Home Office USB Duplicator

Today, like never before, individuals are working from the home office. Working in an favorable situation is decent and beneficial and I think this is why so many love the home office. As favorable as things may be; now and again the home office doesn’t have a computer gear to carry out the responsibilities required. With numerous business now practicing social distancing, one will discover certain things are still needed.

Consider the niche requirement to make USB duplicates at the home office. For instance, let us consider an IT director who needs to turn out bootable restore recover sticks, or a product engineer who is required to send programming updates to a group of remote office sales guys. These managers need a snappy, simple and econimical bit of gear to do the job.

The smaller USB flash drive duplicator by Nexcopy is an incredible solution for this definite issue. The unit measurings is 15cm long and 10cm wide. So it will fit into any computer bag, and light as a book.

Nexcopy USB Dupliclator

The USB duplicator is a one-master to four-target copy station. The duplicator is a digital binary copier which duplicates any file system or structure provided by the master host flash drive. Using a USB cable the duplicator can power the five USB flash drives; however, is not recommended for using with USB hard drives.

With a duplicator like this, making duplicates at the home office is speedy and extremely simple. There are four menu buttons, enter, escape, up and down. The unit will work at the press of a single button, which makes this unit ideal for non technical people. The mini duplicator may be configured to perform a binary copy or a binary copy and compare. The copy and compare function gives the user piece of mind that each copy is exactly the same as the master. Having a verification option will insure every copy is the same as the master, giving the user piece of mind all the copies are 100% correct and exact.

Reviewing the features of the duplicator, we have note worthy features:
  • Asynchronous copy mode, all the time
  • Binary copier will copy any format; FAT, FAT32, exFAT, NTFS, HFS, Ext2,3,4, Proprietary
  • Binary CRC verification algorithm
  • Quick Erase and Full Erase for disk sanitization
  • Four language modes in LCD menu
  • USB speed benchmark utility
  • Firmware upgradeable

Is the cost of the mini sized USB duplicator worth the cost for a home office employee? The easiest way to determine this is asking ourselves how much time the duplicator will save. This mini copy station, called the Nexcopy USB104SA will copy one GB of data to each device in just over one minute. That is extremely fast. If an IT manager or software engineer had to data load a 12 GB worth of data on a PC, it would take about 12 minutes to make four copies. Windows could never copy that much data, that quickly. When using the copy and compare mode it takes a bit longer… about 1.5 minutes per GB. So still incredibly quick.

Several features are worth mentioning in a bit more detail. The Erase function is a technical term to remove all data from the USB flash drive. This is a robust feature which guarantees data is removed from the flash drive with no ability of the data being recovered. Formatting a drive doesn’t clean data from the drive, the format function only destroys the file allocation table (the directions to find data), but erase will actually overwrite random binary data over the data blocks. There are two erase settings available on this little USB104SA, and the quick erase will scrub certain portions of the drive so some data could remain, but most likely the files would be corrupted if trying to be recovered because the random write sequence skips around the drive and over writting just bits of memory. The full erase function will write binary randomly zeros and ones to all the NAND memory of the flash drive. By doing this randomization, it would be impossible for sophisticated forensics recovery software to restore any data.

The four language modes include English, Spanish, Portuguese and Simplified Chinese.

The USB benchmark speed is a great a convenient tool for testing the read speeds and write speeds of a thumb drive. This is even more valuable when dealing with promotional quality media, as this low-end memory is very instable and can get frustrating to deal with. The easiest way to determine the quality of memory is looking at the write speed. With the benchmark utility one can test the read and write speed of a drive. The USB duplicator will write about 20MBs of random data to determine the average read and write speed. If the USB memory has a write speed of 4MB/second or lower, it’s not good quality. If the write speed is above 8MB/second for USB 2.0 media and above 20MB/second write speed for USB 3.0 media, it is of better quality memory.

The duplicator uses the CRC verification protocol. We did a previous article on Cyclical Redundancy Checking and a great read.

The USB duplicator made by Nexcopy is a backward compatible product and will copy to USB 1.0, USB 2.0 and USB 3.0 flash drives. The duplicator will write to the device as fast as it will allow. The best write times will result from the operator using USB 3.0 media.
