Why does my ipod freeze my computer?

my ipod classic 6th gen used to work fine, but now when i plug it in to my win xp computer, about half the programs wont neccessarily freeze, but its as if they're put on hold. like if i click a button on them or try to interact with them, nothing will happen untill i unplug the ipod, then all the buttons i clicked on all go at once. iv never used itunes with it. i use winamp. it has always worked perfectly fine. it was last working about a week ago. my ipod nano 3rd gen still works fine. iv tried a different cable, port, and even a different computer. i tried it on my ubuntu laptop using rhythmbox, and it works fine. iv rebooted my computer many times, but i dont like to reboot it too muchj because i have servers running, and my users get pissed whenever i have to reboot. its not a winamp-itunes problem, because even right after i reboot, before i launch winamp, it will still freeze it. the programs i have noticed that get frozen are winamp, the safely remove hardware utility, and computer management(right click on my computer and click manage). the safely remove hardware thing will freeze if i try to eject my ipod, and when i unplug it, it pops up a message saying something is using it. the pc manage thing wont even start up untill i unplug my ipod. i did drop it a few days ago (it fell out of my jacket pocket onto carpet, so not a terrible fall) and i know that classic 6th gens have harddrives in them, so im thinking it might be a problem with the harddrive. but then again, my laptop with ubuntu and rhythmbox loads it perfectly fine. iv tried putting it into disk mode, but it does the same thing. also, i noticed that the files on it seem to have doubled. a few weeks ago, i was compressing an old backup of my old harddrive (~80 gigs) because i only had about 10 gigs left, and i ran out of room for the compression. so i moved the 80 gig folder to the ipod and used winrar to compress it to my harddrive (whole process took like 3 days). the finished rar was about 50 gigs. i left the 80 gig folder on the ipod, since i was only using about 30 gigs of its room, so no harm there. on the ipod settings screen, it showed an orange (orange means other(ie not music, video or picture etc)) bar that took up ~half the space on the meter. the ipod is 160 gigs, so an 80 gig folder should do that. now the bar takes up almost the whole thing, and it says i have 6 gigs left. i have no idea why it does that. if i had to restore it, i could shepard the music back onto it fairly easily. i got it in late december 2010, so its not old at all. i took it to the apple store and they said it was at the latest firmware. any help would be greatly appriciated. and sory for the long post. if you read this far, thanks for atleast caring enough to finish reading this.
