Would you please elaborate as this seems to run
counter to my experience?

I have had 3 drive fail events with software raid (md)
tools and SATA drives in the last year.  The drive was
taken off-line and I as the sysadm received a warning
message via email.

I downed the systems (after-hours) and replaced
the failed drive. (These machines don't have hot-
swappable h/w)  No problems were encountered.

Two of these systems are running a WBEL-3 and a 2.4
kernel and haven't been updated in a while.  The other
was a CentOS-3, same story.
