I bought a new 5th gen AEBS and installed it yesterday updating the firmware to latest version and enabling the 300mbps 5GHz access point. I formatted a 2.5" USB hard drive to Mac OS Journaled and connected it via USB. Last night I transferred GBs of data with no problems. However I copied my iTunes media over night, and this morning it stated that it lost connection to the drive. I since cannot connect to the drive again without disconnecting the USB drive and reconnecting it. This seems to be a common problem with no evident fixes. Has anyone got a reliable connection out of this device? I was using a MacBook Pro 2010 on SL. If not then I suppose I might send this back and get a dedicated NAS.
