This blog was away during the weekend. It's definitely not for any good reason but hard disk failure at the server. All my files on the server have gone! And, to have my database and files recovered, I believe it's going to take lots of money and time. So, I decided to use whatever backup I have and leave other posts gone.
I'm lucky that I upgraded to wordpress 2 not too long ago and the pre-installed database backup plugin was great. My last backup was 2 weeks ago and I recovered a few more posts from Google's cache. However, my other blog which has not been upgraded to wordpress 2 had all the posts lost!
I hope you all will do more backup so that you won't get the same fate.
