Hello I recently ordered a MacBook and an Airport extreme. The MacBook has not arrived yet, but I have the Airport Extreme set up. So far, I have my DSL modem and my Dell desktop computer both plugged into the Airport, and it's working fine just like that. The indicator light on the Airport is green, and I have Internet on my Dell. However, when I try to plug my external USB hard drive into the Airport Extreme, I run into problems. The indicator light blinks amber, and it says "Disk needs repair. There is a problem with the disk connected to your Apple wireless device. Connect the disk to your computer to repair the disk." The disk works when I plug it directly into my computer, so I know it's fine. The disk is branded Elements, powered by WD. Model number WD2500C035. NTFS format. Any help is greatly appreciated! Edit: Well, apparently Airport Extreme does not support NTFS. Very lame. Any other suggestions? Is using FAT32 on a 250gb drive reasonable? Am I going to run into problems doing that?
