Introduction: Modifying a USB to Work Like a U3 Drive
Note: It's been about 4 years since I put this Instructable up, I recently got a few requests to fix the broken links. That should be all done :)
One of my recent projects was to venture to the shops and return with the holy grail of USB devices:
A U3 Drive
The price for these devices is pretty outrageous. A U3 drive, with half the storage of the equivalent Lexar drive was twice the price! So I went with the Lexar. When I got home, I did some playing with my 8GB Lexar thumbdrive.
I managed to get the drive functioning like a normal U3 drive and I've encapsulated the how to into this instructable.
Step 1: What You'll Need
Step 2: Now for the Numbers
Step 3: Using UFDisk
If you using UFDisk(First Download) then insert your USB, open the program, click AutoRun and set the slider to anything bigger than a megabyte. Then select the image.iso you downloaded earlier and click make.
Okay! that was the hard bit, now for the easy bit! Please skip to step 5.
Step 4: Using UCDExec
Ok, here goes.
Set the AutoRun area size to1MB. set the image to the image.iso that you downloaded earlier. Click burn.
Step 5: Finally!!!
Okay, now that we have got our USB set up, ensure that you cycle the USB - That means to take out, and plug the USB back in. You should have seen both a CD drive AND a USB drive show up in 'My Computer' when you plug the USB back in. If you didn't, then you will have to do some searching for the program appropriate for your USB.
Go onto the USB (Not the CD Drive) and add a file called 'fake-u3.ini' (without the quotes). Open up the file you just made with notepad and write into there:
\(Program you want to run; even a directory to a program)
so for me, its:
Because I'm using the PortableApps suite. THE \ IS VERY IMPORTANT
Just so you know...
This is a very simple VB.NET program, it works by getting all the drives and searching for the 'fake-u3.ini' when it is found, it opens it and opens the EXE specified in the INI.
Also, you should be aware that this doesn't really work the way it did when I first wrote this instructable. Microsoft have disabled CD autorun, so you will have the same outcome as with an ordinary USB drive when running Windows 7 or higher.
Please Enjoy :)
