I have a Lacie Bigdisk Mini network drive, which I use for a form of network backup in my network at home.  This drive was purchased off Ebay a good long time ago.  A few months back, the drive started having some problems, so I diagnosed it as a dying hard drive.    The replacement was nothing but ordinary.  The unit comes apart to reveal a SATA drive burried quite deep in the unit.  It was a little involved getting it apart:

That said, I figured once I replaced the drive, I would be good to go.  But since its a NAS, it needs a mini operating system on the drive in order for it to work.  Loaded up Acronis Trueimage, I see this as the partition table:

What a mess!  Luckily, I put the drive in the freezer for a day, and was able to acronis the drive to a new one, popped it in, and was able to get a working drive.  Had the drive failed completely, I wouldnt have been forced to throw the entire thing in the garbage.  Case in point:  NAS’s are not the best situation unless it comes with its OS on a secondary chip.
