Hi folks. I had my optical drives set up as Secondary Master: Sony DVD-Rom Secondary Slave: Asus CD-Rom My 3540a arrived today and I decided to replace the Asus. After installing and booting I got the "Floppy Disk(s) Fail (40)" message. Since I've never had this problem before I decided to undo everything that I just did. Now, even with my system back to its old config I'm running into the same "Fail 40" message. I searched around online to see what the message meant. Apparently it has nothing to do with optical drives...so why am I getting this message after installing the 3540a? I've tried tightening all the wires just incase I knocked something loose during the install and still no luck. As previously stated, even my pre-install config. is giving me the message. Also, when the 3540a was installed I loaded a DVD into the tray and it wouldn't register the disk. XP had it show up on My Computer but when I clicked the drive it was empty. Please tell me what's going on. Thanks.
