Hi Paul, A USB drive connected to a recent dual-band Airport Extreme may work as a destination for Time Machine backups, but it’s not recommended. This works well for some, not so well for others, and not at all for still others. Even when it appears to be working well for days, weeks, or even months, suddenly the backups may become corrupted.
Sometimes Disk Utility can repair them, sometimes the 3rd-party app Disk Warrior can, but other times they're useless. Then you must erase them and start over! And it's not supported by Apple. See: Mac OS X 10.6 Help: Disks that can be used with Time Machine and: Time Machine doesn't back up to AirPort Extreme AirPort Disks. If there's trouble with this setup, you won't get much, if any, help from Apple. You can use another backup program to backup to a USB Hard Drive attached to an Airport Extreme. <http://www.switchingtomac.com/tutorials/how-to-attach-an-external-usb-hard-drive-to-your-airport-extreme/> Cheers, Ronni 17" MacBook Pro 2.3GHz Quad-Core i7 “Thunderbolt" 2.3GHz / 8GB / 750GB @ 7200rpm HD OS X 10.6.7 Snow Leopard Windows 7 Ultimate (under sufferance) On 13/05/2011, at 4:46 PM, Severin Crisp wrote: > > Paul, > I can not recall the full reason when I tried this, it was quite a > while ago.
