Hi, I have an issue and was hoping someone might be able to give me a hand. I have a macbook + airport extreme + external hard drive hooked up to the AE. On my mac, i setup this external HD to be used for time capsule backups. All worked fine for a while, but no it no longer seems to back up? It just says it got an error while preparing... i've gone so far as to delete all my backups and start from fresh, that didn't help. I thought it might be the HD is bunk, but I seem to be able to get/store stuff on in still... Did apple block this functionality with a firmware update or something? Worked flawless for a while, now nothing, kinda dissapointing, any help would be appreciated. Thanks.
