hey guys, for the past few months i have been running two internal hard-drives in my PC, and i havent been aware of any problems with them. they are both 80gig each. recently i removed the slave one so i could put a different(larger) slave in. though i havent put the larger one in yet, so im just running my pc with the master. i have noticed that my computer is running a lot quieter now with just the master, not really running any better/faster/stabler than what it was...just quieter. im not sure if this is because the CPU is under less strain and the fan isnt running as much, or the noise it was making before was from the slave HDD or anything. maybe i had the jumpers setup incorrect, although both drive worked fine. just wondering if anyone can shed some light. if i want to expand storage in my pc...is it better to just have the one HDD or is it all the same if i have two? im running XP with a 3gig CPU, 1gig RAM and now just the one 80gig HDD. cheers.
