"Dear George I own a Gateway Profile computer. It has been an excellent workhorse. However, after about a year and a half of use I have a problem with the floppy drive. It will not read floppies! The floppy drive looks like it is functioning because its light comes on. But I keep getting an error message that says it is not accessible. I use this computer every day. Is there a way to replace the floppy drive without sending the computer back to Gateway? I sent an email to their online support people. They told me I would have to send it back." --Unwilling
Dear Unwilling The Gateway Profile unit you have is the first "Profile" sold by Gateway. The entire CPU, floppy drive, CD Drive and every other component of this computer, is built-in to the housing that also contains the display (monitor). Due to the Profile's integrated functionality, I'm told it must be opened in a "clean room" in order to replace your floppy drive. That means, you must ship it to Gateway to perform the replacement."
