I bought a new 1.5TB disk which was PC formatted, and got in trouble trying to
reformat it for Mac.  Eventually it froze the Mac (MacBook Pro), but Disk
Utility could still see it if it was mounted after starting the utility.

When I asked here, I got several helpful answers -- thanks -- but when I went
to try them, suddenly not even Disk Utility could access the disk.

I finally received my updated Disk Warrior, and that fixed it in one try.  It's
now my Time Machine target, and seems to work fine.  Thanks for all who offered
their help.

Get a replacement disk.  Seriously.  When you plug a disk in, it should 
'just work'.  Return it ASAP.  The longer you wait, the problems you'll 
have returning it.

I've had 3 Western Digital drives do just what you describe.  The first 
one right out of the box.  The second after a week and Fry's grudgingly 
replaced it because I'd bought the 'extended warrentee'.  The third died 
6 months later and Fry's wouldn't replace it in-store.  So I sent it to 
WD only to get a unit that was DOA.

Never again.

Why would you buy an extended warranty-- they're most always a rip off. 
Especially for hard disks which are either DOA/fail after a few days--- 
or run damn-near forever...

Indeed there's quite solid statistical data on that (and for more than
hard disks - it's a pretty broad principle). There's a classic U-shaped
failure-rate curve. It is high at first (infacnt mortality) and then
again at the end (wear-out), but low in the middle. That middle period
with the low failure rate tends to be what extended warrantees cover.

I might add that the middle period is what MTBF numbers are based on. So
an MTBF of 100 years (number pulled out of my hat for example) doesn't
mean you can expect a device to last 100 years. It means that, during
the middle period, you can expect about 1/100 of the devices to fail per
year. I read somewhere that the MTBF of humans was somewhere around 300
years, based on simillar computations.
