You say replace the harddrive "it is a really simple procedure to perform." Is it so simple to teach me how to do it myself?
1. Absolute easiest diy method is to buy a hard drive that is already prepared for use in your unit. Then you simply open your unit, remove the old drive, and install the new drive.
Step by step instructions are included. Instructions are also online at first 2 below.
The cost will be a little less than you mention above but you will have a much larger drive with hundreds of hours of capacity.
These drives can be found at(among others):
2. The next easiest method is to buy a drive and prepare it yourself using a software product called Instant Cake from dvrupgrade.com. This method requires that you open your computer and connect the newly purchased hard drive to prepare. Instant Cake costs $20 and a new 500gb WD hard drive from newegg.com costs $100. Once you boot with the Instant Cake cd, you merely answer a couple of question that appear on the screen and your drive will be prepared.

3. If you are really good with computers, you can save(possibly) the $20 and use methods at mfslive.org to prepare the drive. You can also copy saved shows on your old drive with this method.
You can also get plenty of help at the upgrade forums. Just start a new thread here: Tivo community upgrade forum(click here).
4. Warning:"...When looking inside your TiVo, you will notice a white ribbon cable running from the front panel of the TiVo to the motherboard. It is a white ribbon cable that plugs directly into the motherboard.
Here's the WARNING: NEVER power-up your TiVo with this cable either slightly or completely removed from the motherboard. It must be firmly seated when you power up the TiVo.
Here's the reason: Doing so can permanently damage your TiVo. In some cases, the TiVo will power up but will not respond to the remote. In other cases, the TiVo will not power up at all (and will just click)...." (more info here)
