How do I clone a USB flash drive to another one? Answered

The premise- The school gave us USB flash drives that have special software in them as a test drive. The software will automatically open when plugged into a computer. I want to transfer all the files in that drive to an Ativia flash drive for 2 reasons:

1- The Ativia drive has more memory
2- I will have to give the flash drive back later on

I have tried simply dragging and dropping all the files, but this does not work. One thing I have noticed is that the USB drive the school gave us was read as 2 separate drives: Drives J and K. That should help some.

In case you are wondering, the flash drives the school gave us are the blue and green bracelets in that picture.

Thanks for your help!


The craze for uniqueness in the industry has led to the invention of one after another variant of flash drives. Both from quality, protection and to the cool and funky ones. Cool flash drives are the recent trend of this age, be it youngsters or aged we all like to carry out documents in our preferred way. While some are over priced for providing you top level security, most of them are quite pocket-friendly and gives satisfy you in your kinda ay.

Have you tried sending the files through a dropbox account? I work for a company called Ampronix and we have server issues across departments and sometimes have to exit our network and send through a third party source(like dropbox).

The fact that it's showing up as two partitions suggests that there's something special about these drives. If so, the answer may be that the drive is copy-protected. If so, you're on your own. If not... Try XCOPY, with all the options needed to tell it to copy recursively, include Hidden and System files, preserve attributes, and so on.

Oh ok. I never heard of it before, so I thought it was a program.

You can not do this because the USB is 2 physical drives, so you need another usb like the U3 drive which has 2 seperate components

Actually you can, the one drive will just be partitioned, not two physical drives.

PassMark's ImageUSB http://www.osforensics.com/tools/write-usb-images.html

Works very well. I use it to clone my Xbox memory flash drive so that I can use it on my multiple Xboxes (not at the same time!)

Here's their overview:
"ImageUSB is a free utility which lets you write an image concurrently to multiple USB Flash Drives. Capable of creating exact bit-level copies of USB Flash Drive (UFDs), ImageUSB is an extremely effective tool for the mass duplication of UFDs. ImageUSB can also be used to install OSFClone to a USB Drive for use with PassMark OSForensics™.

Unlike other USB duplication tools, ImageUSB can preserve all unused and slack space during the cloning process, including the Master Boot Record (MBR). ImageUSB can perform flawless mass duplications of all UFD images, including bootable UFDs.

Warning: Due to the forensic nature of image duplication by ImageUSB, please ensure that you select UFDs with a storage size similar to the image you wish to duplicate. For example, if a 2GB image is copied to an 8GB USB Flash Drive, the drive will only be able to use two out of the eight gigabytes of storage space. In this scenario, users will need to reformat the UFD in order to access the rest of the storage space."

I just tried ImageUSB and it worked great for me. Thanks!

Hi Tried both the softwares they dnt pick up the drive ??

Do you have any other ideas

Are you sure the drive isn't bad? What kind / size.

WinImage has many cool features!

* Create a disk image from a removable drive (like USB drive), CD-ROM, floppy,
* Extract file(s) from a disk image,
* Create empty disk images,
* Inject files and directories into an existing disk image,
* Change a disk image format,
* Defragment a disk image,
* A powerful "Batch assistant" mode that lets you automate many operations,
* And many more!


it is imposible to do so because software simply wont go onto a computer unless you have the main disk to the software

I'd guess that the physical drive has been partitioned into two logical disks. You should be able to turn off the autorun/play through the Properties function for the drive letters.
You may be able to copy these things (what do you mean by "but this does not work"?) - make sure you copy all files & the autorun.
It probably does have some anti-copy device, not sure what it is though..


By "this doesn't work", I mean that the software does not automatically run on the Ativia drive, unlike the smart drive. I do not think it has an anti copy device, its very compact and the people assume the kids can't do this.

You've possibly not copied everything?


I can't see what's on the two drives so I wouldn't know, but have you cloned both drives onto a new stick (including repartitioning it)? L

how can you do that? instructions?


wait for my PM first, there are some details I have to get to you fast; I will send it to you tomorrow

Use mac or linux. Pc will probably have anti-virus/pirating stuff to prevent you from copying it.

Have you tried just exploring the drive?

Yes, how else would I find that the flash drive was read as 2 different drives?

im guessing you probably wont be able to. these flash drives (like the u3 drives) will most likely have a special chip inside that has the rom files for the software partition (the one that probably comes up as a cd.) if so, then you are out of luck. otherwise, daemon tools, acronis true image, or another image/cloning tool would work.

Try pressing shift before you plug in the drive. That keeps windows from running whatever startup software is onthe drive. There may be some startup software on the drive that prevents copying the drive properly. Are you enabling "show all files" in windows files before you copy? In the event that you can't get it to copy, have you tried explaining to your teacher that you are trying to copy and why?
