This happens very frequently with my Bering Totem Drive as well.
I can live with 'kur-chunk'; is any damage being done?  Regarding
the 'negative ion generator' ... Yikes, is this a hard-drive component?

SCSI controller sensing, perhaps erroneously, that the drive media
has slowed down ... Any ideas?
