AirPort Extreme tells me "Disk needs repair"

I have an AirPort Extreme base station with a brand new 2TB Iomega USB disk connected to it.

I have set up the disk through the AirPort admin utility and set a disk sharing password. Works fine.

After trying to copy some files to the disk (larger files) it was unmounted and Finder gave an error on the copy task. Disk unmounted. Now I get an orange light and the base station tells me there is a disc error (needs repair). Connecting the disk to my mac, all is fine.

After reading a bit I decided to re-format the disk, check that the partition also was in the right format. They where, but I did a new format anyway. All good. Connected it back to the base station, it worked.
Tried to copy again and half way it gave the same error, now I get “disck needs repair” again.
Anyone know what I can do to fix this?
Base station is running latest firmware, disk is brand new and works fine on my mac.

I'm trying to use my iPhoto library from the disk. It's fairly large.

But I did not use that file when the disk died.


I don't think the disk error has to do with the file as the disk is ok and file permissions etc are ok when I connect to my Mac.


If the disk does not manage larger file, what is the point of air disk? How can for instance apple offer OTA backup to time capsule?

After some additional research (including talking 2 hours to 2. line of Apple Support) I have discovered the following:

Airdisk has problems that are oriented to both hardware problems (known but not solved by apple) and on the latest editions of the base-station a firmware problem. Upgrading to latest firmware SHOULD fix the unmount / disk needs repair msg on the latest devices. (this is unconfirmed as I do not have a new device, just the 1. gen base station). My (norwegian consumer purchase law) product protection of 3 years had just lapsed so apple said “sorry, cant help you”, once we figured out it was probably hardware error on my 1. gen. device.
So; if you want AirDisk, make sure you get a proper confirmation from Apple that it WILL work on your new device before you buy a base station. Got an old one, sorry your out of luck.
