This first one is like the one that doesn't work.  Of the three, two didn't work correctly and the one that works without errors isn't that fast either.  I wouldn't recommend this one unless something has changed which makes it much faster in the case of the one that works and is dependable in the case of the two who doesn't. This next one is the one that works great.  It's fast, every bit as fast as my internal drives.  I have not tried the USB port so I'm referring to the eSATA port only.  Let's hope they haven't changed this since it works great.  The display is hard to see on the main image but another image shows it well.  I might add, the price has went up quite a bit too.  o_O One other note, neither of those are the vendor I bought from.  The original vendor had sold out and either unlisted the item or no longer had all the info.  I'm sure there are others out there that work fine.  I'm just sharing the ones I have that don't work right and one that does.  Just like hard drives in general, I'm sure others will have different experiences.  Dale :-)  :-)
