When it rains, it pours (dead harddisks)

A few weeks ago was the end of a heat wave.  During the heat wave a hard disk died.  I RMA'ed that disk, but a week later, another hard disk died.  So far, I have not lot much data.  I manually stripe files across hard disks. When the first died, I re-striped.  When the second died, I did lose some data.  It got me a little worried, so I decided to create a ZFS pool with blocks on multiple disks.  I started coping all of my data to the pool.  Although that experience will be written up in a different blog post, I wanted to bring it up a little bit.  ZFS has a WONDERFUL feature that allows it to CRC the entire pool to identify any problems.  I ran the CRC a few days ago and discovered that a 3rd hard disk is dying!  This one is a brand new disk that I purchased.  The only data on it is the ZFS pool blocks, so I can replace it with a new disk, but this is getting kind of ridiculous.
