In the "Wishlist", the request has been made for Linux support.


Just so I can understand what's going on here ...

Does "dd /dev/zero /dev/sdx" to the unmounted usb key followed by repartitioning / formatting work to remove this crap?

It would have to be "dd if=/dev/zero of=/dev/sdx bs=512 count=1" and
I don't know if it'd work or not.  Unless there's some hardware flag
on the drive that turns the U3 portion into a read-only physical device
it should work.


Sorry 'bout the lazy "dd" command.

Yes, it would seem that it should work, but people are reporting that they had to get a "Windows using friend" to fix the thing. I don't have such a device, but I may in the future (and I don't do Windows), so I was curious.

Thanks!

John


I tried that on one of my SanDisk Cruzer the other night. I tried different versions of dd, even to the point of over writing the whole drive using dd.

From what I could find, the partition that is uses is a read-only partition and is hardware controlled. Some code in the removal software must turn this on/off. I know that the windows software writes directly to the video driver and won't work with dual display monitors.
