"All important things"
That's everything. I have school papers, and everything.
then copy everything... thats what I did with my jumpdrive. Then I did a Chkdsk /f which somehow found 2GB of lost chains, which was odd given the drive was only 256MB. and then it only wrote 50MB worth of CHK files.
I actually managed to rebuild two of my larger projects my combining the CHK files with COPY, opening it with my text editor and searching through the file for portions of text in the 4KB of the file I wanted that I still had... needless to say it was a very time consuming process.
However, the difference here is that my files were corrupted(as opposed to mysteriously dissapearing), since my laptop at the time was a finicky little fellow and sometimes froze solid causing me to remove the battery to restart it- sadly this was usually while accessing the files on the drive, too
- in your case it's the "move to folder" menu command. Is this when moving to or from your USB drive?
Another good strategy that I also followed for a time was periodically copying everything from the drive to my HD. Now I work from my HD on account of only needing to sync my laptop and desktop, and not really having to use foreign computers such as those that were at my school.
