Limit on number of external hard drives?
Does Windows 7 have a limit on how many USB external hard drives it will use? We have 5 WD My Book 1TB drives; 4 of them are recognized and work just fine with Windows 7 Home Premium 64 (which we recently did a clean install of to replace Vista Home Premium 64), but the 5th one doesn't show up with a drive letter (in Computer or Windows Explorer), even though it does show up in Control Panel. The one we are having trouble with has had the latest firmware and WD SmartWare installed, and our computer has the most current Dell BIOS installed. We know the drive works, because we can plug it into our other computer which has Windows XP on it and it comes up with a drive letter just fine. Just wondering if there's a limit on how many of these you can use with Windows 7, since we had no problem with the drive until we installed the new OS.
