Losing a thumdrive

Darn..Lost my 256MB thumbdrive yesterday. Look high and low for it. Looked in office. In toilet. In house. Cannot find it. Worst thing is ...I have my passwords for a lot of websites in it. Darn. Luckily I still had time to change the passwords before someone changed it.... If not... There goes my checks from Google Adsense..

So note to myself. Next time, I need to install some sort of encryption software to password protect my data on da thumbdrive. How does 1GB sound to you ?
