My experience is that it takes a long time to index the drive and that access time is slow. Also, it is not certain whether the Touch will power that drive.
Additional transmitter/receivers can complicate the matter. To determine if it is a wireless problem, run an ethernet cable from the SBT to the router and see if that has any interruptions.
In my case, I had to deactivate the WiFi in my PC because it interfered with the signals from my router.
It is hard to know exactly what is feeding the SBT unless you defeat one. At least, that's how I figured out my problems with a PC-based system. I have no idea what is involved with Apple stuff and I had to look up AEBS.
I have used the Touch in 3 systems, wired and wireless, and not had any problems. If you are having problems, it is external to the SBT or, possibly, you have a defective one.
