The 750gb seagate in my HP is giving me all sorts of problems with slow boot times, slow shutdowns, taking an age to anything, I've swapped it out for an old 200gb WD drive and have had no such problem. Scanned the seagate for errors etc nothing. Tried to install win7 on it today gave up after 2 hours (took 25 mins on wd). Anyway cut a long story short after a bigger drive please. Have tried firmware update etc for seagate as web shows problems on certain types.
