ok. here's the deal. i recently upgraded my hard drive, from IDE to SATA. now i copied the contents of my IDE hard drive to my SATA hard drive, but forgot the registry files. henceforth when i started steam, weirdly it only recognized that all the old school half life, and cs was installed, and curiously 5% of hl2 deathmatch. saying that cs source, and hl2 and the likes weren't installed, even though they were in the correct directory. now i went to reinstall, but copied the game files to a different location, and reinstalled the whole lot again, and copied the game files back across, to save having to update them all again, now pretty much same issue again. so i try using steam, and going and clicking on install game, plenty of hard drive space, and basically steam turns around and tells me i dont have enough hard drive space. what should i do to fix this problem??? this is getting annoying. the only thing i can think of is to completely remove it, and start from scratch, reinstall the whole lot and see if it will allow me to update all the games... other than this, is there any other scenario that someone can think of that'll help me out? thanks
