That's the strangest thing I've ever heard.
Yep, very strange. I wish I had a decent video camera so I could prove I'm not just going mad
Searching around, there was a thread about speaker proximity and whether magnetisim might mess with the drives. The general consensus then was that magnetism shouldn't really be an issue. If that's the case, I can only assume it's the circuitry for the VFD that's causing it. Sliding the lid back so it's still covering the drive, but about 1.5" away from the display stops it, which seems to back that up. Can't help but wonder if it might explain some of the other mysterious intermittant drive problems other people have experienced?
