After updating to the last firmware version for my Airport Extreme (7.2.1) our MyBook USB hard drive which had worked perfectly until that point disconnected and will no long mount giving an error of wrong password. After spending two days resetting the Airport I replaced the MyBook it with a spare external hard drive I had setting around. I reset the Airport and that replacement hard drive showed up and has been working ever since. Even though I have heard reports of this happening it was kind of a surprised to have it fail after the firmware update. So all you MyBook owners be advised. Update the MyBook was moved to my G5 tower where I ran DiskWarrior 4 on it that found lots of little errors. After the directory was rebuilt I returned the drive to my Airport Extreme rebooted the Airport and all was well again. Just proves you can never have too many hard drives setting around.

I have since gone back to the 7.1.1 firmware and my drive problem has got away. 7.1.1 was very stable and 7.2.1 very likely to disconnect and then refuse to let me remount the volume telling me I used the wrong password. Apple needs to get a Firmware version of this working correctly, VPN is also a problem for some users, so if these things worked it would be the perfect wireless router for all my clients.
