This is just a warning to people to take care when using new
hardware ;-)

Got my replacement home server running, everything seemed to be ok
(low power consumption, 4 drives, SATA3, i3 so effectively four
cores).  And then, after fixing up the kernel config so that I could
access external drives (I had not realised the mobo only had a USB3
controller, I'd assumed the USB2 sockets used an earlier driver) I
started to write backups to an external disk.

With four internal drives (sda system, sdc /staging for all my boxes
to rsync to for backups, RAID1 sdb and sdd as /dev/md0 for the final
backups and other data) I had assumed the external drive would be
/dev/sde1 like on the previous box.  And the first time, it was.

But then I unmounted that drive and inserted another.  And suddenly
the new one had become /dev/sdd1.  I then reinserted the original
external drive instead, and it too was now sdd1.  I've now moved on
to backing up some other stuff to a third external drive - still
sdd1, but I bet at some point an external drive will be sde1 again.

Just when I thought I understood device naming 8-|
