	They are a low-pass filters. They make sure that the high frequencies generated within the drive stay in the drive. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	Given http://cr4.globalspec.com/thread/79624/Laying-of-cable-reg, is the drive CE-marked by the manufacturer? Are the chokes inside the drive itself? Please respond. __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856
