Flashdrive has autorun files that cannot be erased. U3 or not U3?

I have several flashdrives that have a powerpoint configured to autorun.  I need to re-use them but the files cannot be erased.  My Computer shows 2 drives when it is inserted. One "G" is a removeable drive with (now) FAT32 formatting and it can be written to.  The other "H" shows s a CD drive with CDFS formating and the files are read only.  I have tried to repartition using Disc Management but all I can do is change the name of the partition.  I've bee searching around and looked at some U3 sites but the two things I've tried cannot see it as a U3 drive.  Maybe it's not?  This looks like a real tough deal from what I've seen so I'm putting 500 points on it.

  Do you have the format option available to you when you right mouse click on it? Try opening a command prompt and "format g: /fs:fat32" it might not would but should offer some valuable insight.

I've tried that but I end up with a "this volume is write protected" message.

>> this volume is write protected

Look for a physical switch of some sort on the drive.  This may be on locking the drive being written to.  Or Windows has identified it as CD format and says no format allowed.

You may need to switch to another tool rather than Windows.  Try a Knoppix Live CD and see what it can do.


No guarantees.
Your help has saved me hundreds of hours of internet surfing.

See if  the HP USB boot utilities will do it:

HP USB Disk Storage Format Tool Version 2.0.6

HP Drive Key Boot Utility Version 7.41 (says Windows 2000, Microsoft Windows Server 2003, Novell NetWare 6.5, but might work in XP)


nobus: no dice.  I've tried these and after I insert the flashdrive (when requested) it is not recognized (as thought nothing had been inserted).
coral47: no dice here either.  This issue seems to be that the drive is recognized as a CD-rom so anything that tries to do something to a flashdrive can't see it.
dbrunton: no switches of any kind.  I'll try the Knoppix later but it's a 45 minute download so I can't do it now.  I shall update when I've tried it.

nobus: No dice still.  the ehow link leads to the same U3 Launchpad removal tool that I've tried before.  No matter what I do it cannot find the flashdrive.  I've tried it several times with it flashdrive in before running it and after running it.  The programs never sees the drive.  I've even tried different computers. Interestingly, if I remove the flashdrive while the uninstall is running it closes so there must be some kind of connection.  I'm begining to feel that somehow I'm not using it correctly.

What about the program that did it in the first place?
Does it have a 'unmount' option buried somewhere?
