Advertisements Ok .. Is this normal. My tivo has a single drive set up at the moment. I have a dual drive setup to put in. One thing I have noticed is during the cachecard boot. Normall It says 512MB database being cached (on 512MB Ramm - so no harm no foul)... When I have two drives in and configured its says teh database is 521MB - which to my mind is two big for the 512MB cachecard ... Am I right ? Is this normal ? Gas.
