Airport Disk performance issues...
airport_disk
It appears that my Airport Disk has hit a serious slow down rendering it effectively useless for data transfers (Data transmissions kit 300-400 Kilobytes a second, not good for transferring 32 Gig of data... I have read many suggestions including reformatting with HFS (no journalling) and replacing the disk / usb enclosure etc... For the time being I think I will try an airport reboot and a disk defragmentation and see how that goes... Fingers crossed.
