unusable memory stick

Hi
I went to a seminar yesterday, and all the presentations were provided on a 2Gb memory stick.  All very nice.  I've now copied the presentations on to my computer, where they'll be very useful.
I then tried to delete them off the memory stick, but they won't delete.  Tried to reformat the drive - won't format.  On looking at the disk on Windows, it has a size of about 1.8Gb,
Can't delete the partition.  On top of that, actually reading the stick is very slow, and if it's plugged in, I keep getting delayed write failed messages, even if I'm not actually reading or writing to the stick. I can't write to the disk either. (There doesn't seem to be a write protect switch either - so it's not that)
It's only a 2Gb stick, so its not a big deal, but I'm intrigued as to how they did it, and if it can be undone.
Any ideas?
John

If that is similar to the Sandisk U3 mechanism then you might find that this tool http://u3-tool.sourceforge.net/ will allow you to delete the CD partition on the memory stick and get the space back for normal read/write.

Thanks Oldjim - that looks like it, but id so they had them made up very quickly.  I know for a fact that they didn't get one of the presentations until the day before the seminar! I also can't write anything to the stick.  It takes ages, then comes up with an error message.

It may be protected with a password or some similar thing. If you could use a Linux Live CD to boot into a Linux system you could possibly circumvent the protection. A member of our computer group (a computer dealer) often does this when customers have forgotten their password.  Another way would be to boot "GParted" from a CD and delete the files with that.
