Some models of Seagate drives have a known firmware bug which causes these symptoms. You should try to get a firmware upgrade from Seagate technical support. Meanwhile, you can work around the problem by disabling the write cache on the drive. Use "camcontrol modepage ..." to do that (see the man page for details). The page you want to edit is page 8, and it's the "WCE" flag that you want to turn off. Caveat: Don't mistake me for a SCSI expert. I got this info from Justin Gibbs and it worked for me.
