Emax

Can someone offer me some direction as far as navigating the hard 
drive on an Emax SE HD? I purchased one off of E-Bay some time ago and 
it worked fine for a while. I was able to access the sounds off the 
factory loaded hard drive with no problem. Then the hard drive stopped 
working, so I opened the unit up and re-seated the cables and it 
functioned again. After it stopped spinning a second time, I opened up 
the hard drive case and spun it manually. I put it back together and 
it powered up, spun and the display stuck on 'loading software' after 
initially saying 'diagnostics'. Thinking that it was the hard drive, I 
bought a re-furbished one off E-Bay, but I am having the same problem. 
I don't see anywhere in the Emax manual or SE manual where it tells 
you how to access sounds or save sounds to the hard drive. Any help in 
these matters would be greatly appreciated. Sorry for the long winded 
inquiry. Thanks in advance, -Angelo
