Yes, the reported objectionable behavior at computer shops, is
reformatting customer boot disks, just for the hell of it.
Nobody asks the customer, and when the computer comes back,
there is a shiny new OS install, and no data files.

There are two ways to make a convenient backup device. Buy
an enclosure and a bare disk drive, and assemble it yourself.
But in the OPs case, I figured most consumers would want to
buy a drive already in a nice little enclosure, because not
everyone builds their own stuff.

What I've noticed for pre-built disks in external enclosures,
is an abnormally high failure rate. The 2.5" drive in question,
does not appear to suffer from this. But it would seem like
prebuilt 3.5" drives tend to "drop like flied". There was one
poster, not too long ago, who used an external 3.5", backed up
their data, and a few days later, expected to restore to a new
disk. The drive was dead. And there are repeat stories like that,
leaving me to conclude that perhaps a 2.5" is a better choice.

It seems a lot of externals now lack fans, and my own personal
preference in buying bare enclosures, is to find one with a fan.
It is getting hard to find a reasonably priced product, that
comes with a fan. On the last one I bought, I even had to drill
holes, to provide a place for inlet air. Some fan equipped
enclosures, have no other holes for intake! So all the fan can
do, is swirl the air around a bit.

I've just gotta ask: is there anything wrong with using a bare drive with just the adapter-wiring for a backup disk? Have to protect it from static electricity, of course. Just eliminate the enclosure and seems to me it will run cooler than cooped up inside those 'air-proof boxes'. BTW: I have probably 4-5 enclosures on hand and only one of the wire-only-adapters! s



Exposure to the air, has got to be better than being cooped up in a
sealed plastic box.

The risks to the raw drive, are static discharge (ground yourself to the
computer case before touching). Also, the risk of a mechanical shock to
the drive - like dropping an object on it. An enclosure is elastic to
some extent, and reduces the shock level.

The power dissipation of the 2.5" and 3.5" drives is quite different.
When I looked up that WD drive, I was surprised to see that the peak power
was 5V at 0.5A (2.5W). Which is a lot less than a 3.5" drive that is using
12V @ 0.6A and 5V @ 1A. Although there are probably a few 72000RPM
drives now, in the 3.5" size, that have better numbers than the ones
I typically quote. I use my 12W worth of power numbers, to try to make
sure the power supply will be big enough.
