You can then develop an automated way to cut power within a millisecond of the overwrite process starting and maximise available data. To perfect this technique, get an electrical engineer to work with you to monitor power consumption of the U3 device chipset to characterise when the overwrite begins, it should be a big sustained jump in power as the control chip initiates overwriting of all blocks. This may be fixed in newer implementations by having a flag in the controller that only allows access back to the removable device when overwrite is complete and just resumes overwrite on power up.

You then may have access to unallocated space and carve away, however this will overwrite some data and is taking advantage of a poor implementation. Harder - if you trigger the wipe process which also clears the pwyou can sometimes kill power to the device before it has a chance to overwrite all the storage space. Easier - take advantage of poor implementations as others have found - check pagefile and hiberfile for passwords or find some other way to get the password. The data is not stored contiguously on the flash memory, so if you change the controller, it will have no idea about the order data is stored in on the flash media. Flash memory implements wear leveling through this chipset en. You cannot just remove the control chipset and replace it.

In most cases, if you enter the password incorrectly a number of times, the control chipset will initiate the entire flash memory being overwritten. You therefore cannot take a physical image or start to try to brute force encrytion. The removable storage device component of the U3 is not accessible by the host and does not even appear on the bus until this security mechanism allows it.

When security is implemented in these devices, only the CD-ROM device and CDFS are presented to the file system where some software resides controlling access to the removable storage device. Encryption aside which is another issue in U3 devices, as discussed, the controller presents itself to the host as two separate devices, a CD-ROM device and a removable storage device. In a USB thumb drive you esentially have a controller chipset and flash memory.
