Hello, i have a dell latitude r400gt laptop. it had a 120gb hard drive in it when i found it in a car at a local junkyard with windows xp and internet explorer 8 installed. it worked fine. i decided to put a 160gb hard drive into it since i had one just laying around. i put the windows xp cd into the cd/rom bay and started it up. it statred to format the disk. when it got through, it said something like it couldn't install windows xp. now i hear beeps when i put that hdd into the laptop. at first the bios froze, but now i can flip through the 6 pages ok. still get beeps when i put the hdd in. what happened? is the hdd any use anymore? windows will start to install, but when it finishes the dreaded blue screen pops up. any help would be appreciated. larry
