I had an external WD Book that went bad ... but I wasn't running it
24/7... just occasionally, but sometimes I would forget to power it
off and leave it running for days. When it did die I figured it was
the heat rather then then anything to do with power adaptor. Thermal
test showed me that high RPM desktop external drives can get very hot
in those cases.
I am now running a Fathom External SATA enclosure that came with a
Hitachi drive ... it also supports USB2. It runs 24/7 and I have been
operating it continuously for three plus years. The difference is
that i hooked up a case fan in front of it that constantly blows air
through the enclosure. I haven't had any issues at all with the
drive. I think heat has more to do with external drive failure then
does an external power adaptor.

Hello Thane,
Yes, do the business and shut them off. With the new SATA HD's out now it does
not require much power to run them. Just don't run them 24/7
