You should.  I just spent the last week digging through restored data files I was able to pull off my brand new SATA 120GB HD.

Last week I tried opening a VS Project and started getting CRC errors.  I tried another, and got more CRC errors.  Opening individual class files failed too.  I ran chkdsk, and it failed, after about an hour, with an unspecified error.  When I opened Windows Explorer, my entire Visual Studio Projects folder was gone! 

After staring at my monitor for about 5 minutes, I remembered I have my bigger projects in Vault source control, so they should of still been ok.  I checked and they were.  It was all the smaller apps, half started projects, and experiments that were gone.  Still, they had a lot of useful code and such in them. 

I picked up a copy of Final Data data recovery software.  You probably wouldn't pick this type of software up unless you needed it, but if you ever do, I would recommend it.  Although it took a while for me to go through and restore the most important stuff, I was able to do it without to many unrecoverable file.  A few folders were completely gone and showed up as zero byte files, but I'm pretty much back to normal now. 

I spent some of this weekend putting everything in source control, on a new external HD backup and burned to DVD. 

Now to go pick up Halo 2 and work off the stress.  Look out, if I read your blog and you list your live account, I'll be looking to frag ya!
