Another hard disk dead

It's that time of year again.  The seasons are changing.  I have to mow my lawn again.  The temperature is getting warmer.  Hard disks are dying!  I had expected that moving my server into my basement would reduce the deaths of the hard disks.  This death might be a little unique, though.  The hard disk is brand new.  I bought it 3 months ago.  It is a Hitachi 4TB hard disk.  I never had a Hitachi before, but it was 4TB and it was on sale for the same price as Seagate and Western Digital 3TB disks.  I decided to take a chance.  At 3 months, I consider this hard disk a dud.

My server has 7 hard disks attached to it, although one of them is an SSD (the operating system).  Five are inside of the case while 2 are in an external eSATA enclosure.  The Hitachi is in the external enclosure.  I know the enclosure is fine, since there is another hard disk in it that is working fine.  This hard disk was my first chance to really expand my capacity.  Most of my hard disks are between 1.5TB and 3TB.  I previously combined two 1.5TB drives into a single 3TB device and two 2TB into a 4TB device in my RAIDZ.  The 4TB drive replaced the two 1.5TB drives, matching the capacity of the two 2TB drives.  With the 4TB dead, I'm running in DEGRADED state until a replacement can get shipped to me.  I don't need the capacity yet.  Right now, the biggest thing driving my data growth is doing backups of my Windows PC, but I barely use it anymore, so I was able to reduce the backup frequency.
