Hey guys I just bought an Akai dr8 digital 8 track recorder from a retired sheriff's deputy off of craigslist. It was working when we tried it out at the guy's place. We plugged in headphones and could listen to all the songs that were already stored on the drive. When me and my drummer got it back to my drummer's place it wasn't working the same. We could turn it on and we could send signals through it from a microphone and hear what we were saying through headphones. The problem is we can't record now, even though we could at the guy's place. Everytime we hit record it says sys err 13. Also, all the music that was there before is gone. It seems to me that the recorder simply isn't allowing access to the hard drive. Anybody know whats going on?
