A week from hell. I had to redo the HDD and now I get this annoying unknown device. One partion, fresh install from Windows 7 disc provided by Dell. Downloaded all available drivers from Dell and then some. Still can not find out what this driver is. Everything from battery to wireless network switch...none of which have worked. Does anyone have the EMCS.sys file.. I think that is the filename. I'm on a different box without access to that data right now. I read that if you don't have this file in your system32 folder it might fix this error. Tried to download it but can't seem to find it on a legit site. Lots of scammers though.
