Remove U3 from an USB flash disk
This "SanDisk Cruzer" USB flash drive has this nasty U3 thingy included. Every time it connects with a host, this
U3 partition reappears and gets in the way, trying to do super smart stuff.
So, how to get rid if this
malware feature? Overwriting the whole device did not help. There's a removal tool...for Windows. There's a removal tool for Macs too, but only up to MacOS 10.6 :-\
For Linux, there's u3_tool. This hasn't been updated in a while but let's hope we won't need tools like this in the future. Here's a short description to get
svn co https://u3-tool.svn.sourceforge.net/svnroot/u3-tool/trunk u3-tool-svn cd trunk u3-tool-svn aclocal autoconf automake --add-missing ./configure --prefix=/opt/u3-tool make && sudo make installAfter the build completed, let's use it:
$ /opt/u3-tool/sbin/u3-tool -i -v /dev/sdb Total device size: 1.88 GB (2017525760 bytes) CD size: 16.00 MB (16777216 bytes) Data partition size: 1.86 GB (2000748544 bytes) $ /opt/u3-tool/sbin/u3-tool -p 0 -v /dev/sdb WARNING: Loading a new cd image causes the whole device to be wiped. This INCLUDES the data partition. I repeat: ANY EXISTING DATA WILL BE LOST! Are you sure you want to continue? [yn] y $ echo $? 0And it worked :-) Good riddance, U3!
