My half-full terabyte external hard drive seems to have died. I opened
the case and there doesn't seem to be anything visibly wrong with the
drive, and it was working just fine earlier today (even ran a checkdisk
to be sure)...it just doesn't spin up when powered on. Hopefully it's
just the enclosure. Have ordered a new one, which will arrive in two or
so days.
Will be *most* put out if the drive itself is dead, though losing a
little over a year's worth of data and effort at organising things isn't
as bad as eight years'.

Eventually you'll learn to buy two. :-)

I ordered stamps from Zazzle that read "Place Stamp Here".

Well said - guess there isn't a convenient modality for backing up 500GB of
data?
I've lost count how many times I've had to fall back to backups. Saved my
ass quite a few times...!
Greatest one was when I was working in a dispatching center for fire /
emergency. We had tens of thousands of patient and incident records on file
(in a custom developed Unix-based system) and up to five years or more
after the fact, firemen and paramedics could be called to testify in a
court about a shooting / rape / assault / fatal house fire, etc. Then they
would want records - accurate records - of times, who attended, what was
logged, etc. Failure to produce such could land you in contempt of court.
No less than FIVE times during my seven year career there, -I- could have
conceivably gone to jail for NOT having the records the court demanded - if
I had NOT made backups...!
But then, then volumes weren't at your level. Good luck in getting the drive
working!

What connector does the actual drive have? Can you plug that directly into
a desktop PC?

There is - but not for sane prices, no.

A 1.5 GB SATA Seagate Barracuda drive costs a mere $95 from newegg.
I guess that arguably is an insane price - insanely cheap.

I don't know, man... Backing up spinning disk to... spinning disk? Is
that such a sensible idea?
(Then again, I don't have any hard data on the reliability of HD verses
tape verses CD. I've heard that spinning HD up and down wears it out
faster than keeping it spinning, but I don't know if that's true...)

Mirroring (or duplexing) provides a pretty good degree of data protection
because the odds of both drives dying at the same time are pretty small.
It's been used for a very long time.
But I also back up directories from several systems to other systems
using rsync.

Well, I didn't say anything about shutting the drive down.

I do this daily, the thing is it is spinning disks on separate servers, from
different manufacturers, on different operating systems, each of the disks
being of different age since purchase... I'm sure you see how spreading the
risk applies, and thus increasing the percentage change of a backup
surviving.

Me too - works well.

I've seen this phenomenon on older drives. Had a HDD in a system here that
was left on for years, probably been turned off 20 or 30 times in its
useful life. The fortieth or forty-fifth time the server was turned off,
the HDD died - after running reliably (while not being turned off, ever)
for 5 or 6 years. Ok, old hardware and an old drive, but just goes to show.
Keep 'em spinning is better than spin-up / spin-down on a daily basis.

This is not the same as a backup.
RAID will protect you from physical failure of a single drive. It will
not protect you if you accidentally delete a file, or if some virus
infects your PC and deletes your stuff, or if the filesystem becomes
corrupted somehow, or...

Now that's more like it.
> Well, I didn't say anything about shutting the drive down.
An often-encountered backup strategy is to copy everything onto an
external USB HD and then put that somewhere. I'm not sure that all this
turning the drive on and off won't just wear it out faster.
PS. I've yet to find a consumer RAID controller which actually works
properly. They all seem to be hopelessly unreliable. And most of them
are software RAID anyway; the controller is a normal IDE or SATA
controller, and the Windows driver does all the actual RAID functions in
software. It seems that only the £££ server-grade controllers actually
do the job properly.
