Umm...can ccd(4) make a SCSI drive go CLANK!?

I striped 3 * 2GB Seagate Hawk-2 drives to make a news spool, under 
FreeBSD 2.1.5-RELEASE.   Actually, two of the drives are 8-bit 
ST32151N, the third is an ST32155W, which is the same geometry, just 
a 16-bit bus.

It ran fine for about six hours, then....blew up.  System was trying 
to reboot when someone looked at it, but was asking for manual fsck.  
He also reported the disk was making noise...  I could hear the armature 
clanking through the phone.

Here are the log messages:
