[ale] "undeleteable" file

[PBoyington at polyengineering.com (Preston Boyington)]

I have a file/folder on my usb drive that is corrupt.  In the file name there are squares/numbers/?/+ and other such junk.  I believe that when my friend was using the drive he unplugged it while a transfer was in progress or maybe his XP machine locked it up.

My problem is this: I can't delete the file from Windows or Linux.  I booted to a Knoppix disk that I had and it barfed when I tried to delete the file (gave me a similar error message as Windows, actually).  What is the best way to remove this file from the drive?  Worst case I will remove all my good information and format it (8GB), but was hoping for a better way in case this should happen again.

Thanks,
Preston
