No - evidently not, I must have missed it.

How does that work anyway?
What does a "cold hard disk" do differently than a warm one?

It shrinks. If the problem was friction, the increased distance between
the pieces could allow the spindle or actuator arm to move a little more
freely. If the problem was due to a tiny crack in a trace or other
electrical connection, the shrinking of the board could bring the sides
of the circuit back in contact.

It doesn't work in every case, but there are enough people who say it
helped to make it more than an urban myth. Depends on what the problem
is. Obviously if the fault is a blown component this will not do anything.

What's important is to not boot from the drive, and if possible to keep
it outside the computer, so as to maximize the working time while it's
still cold. Having a USB caddy available would be good, with the
computer already booted up. Most of the time (if it even works) it's
only temporary, so you want to get as much data off to another drive as
quickly as possible.

If all else fails, and before you give up completely, if you're going to
try shopping around for another circuit board, make sure you get not
only the same make and model, but the same firmware version. Here's an
inspirational link written by somebody who's been the

Actually, microwave might be too dangerous as it's metal on the outside so
I'll skip that - but I'll try heating it to change the operating
parameters
in the other direction.

Forget the microwave oven. You'll ruin the electronics and possibly the
motor too.

Try warming it to 50 deg C on a radiator or other dry heat.

Beyond that - employ a recovery company , I reckon.

I had already purchased a twenty-five dollar "SATA/IDE-to-USB 2.0 Adapter"
which plugs into & powers any 2.5", 3.5", and 5.25" IDE/SATA hard disk.

I put the hard disk in the freezer again and attached this naked hard disk
drive to this IDE-to-USB adapter into a good computer. That way, it was a
secondary disk.

When I powered the IDE-to-USB adapter, the naked hard drive made clicking
sounds for about 30 seconds, as if it was trying to find something it lost,
and then it went silent. Nothing showed up as a mounted drive like when I
tested with a known-good naked drive.

Here's an inspirational link http://www.deadharddrive.com/

I'm off to the store for some Torx screws since I have a second drive.

From the sound of things, I'm guessing the disk itself is OK but that the
components to get the data off the disk are bad.

Has anyone tried moving the "platter" from one 2.5" laptop hard disk to
another? Is it worth trying?

Heh heh. I'm in California. We don't have "radiators". All we have is a
little forced air heater which fits in a corner of the closet which we
almost never turn on. But, I think I can put the hard disk drive in the
oven at about 200 degrees and try again.

Beyond that - employ a recovery company , I reckon.

I'm not as worried about the data as the kid is. I'm really trying to learn
so I can be ready for the next big one.

I checked recovery prices and they are exhorbitant. That's why I'm looking
for freeware. It would be nice to recover the data but it isn't worth ten
thousand dollars (that's what some companies charged).

So far I've tried (and failed):
1. At 72 degrees F, plug it into the USB (via IDE-to-USB adapter)
2. Cool it to 30 degrees F and plug into the IDE-to-USB adapter
3. PC Inspector File Recovery freeware
4. Recover Data for FAT & NTFS freeware

Did I miss it or is there a recommended freeware crashed disk data recovery
program that can get the data bit by bit out?

Thats the drive attempting to read the platters and eventually giving up on that.

All that shows is what you already know, that the drive has died.

Correct.

Its not practical to do that, its close to impossible to get the platter
back on the rotation motor accurately enough so that the tracks
arent eccentric. The tracks are written to the platters after the
platter has been mounted on the rotation motor in manufacture.

You may find that changing the logic card may see the drive work.

Indeed. He's crying over the loss of his data. I'm trying
to be syphathetic but personally, from an adult standpoint,
I'm not too worried about it. But, it would be nice to
recover it so I'll keep trying for a while.

Since cold operating parameters didn't work, I might try putting the
hard disk in a zip-lock bag and heating it, either via the microwave

That wont work, hard drives dont have anything that will absorb microwave energy.

or the oven

That should work. But heating is very unlikely to make the drive work.

or boiling it in the water-tight baggie.

No point in that over the conventional oven.

Actually, microwave might be too dangerous
as it's metal on the outside so I'll skip that -

It wont work anyway.

but I'll try heating it to change the operating parameters in the other direction.

Makes more sense to try a logic card swap first.

Does anyone know the maximum heat a hard disk can take in the oven.
I'm thinking about 212 degrees (pot) or perhaps 250 (oven).

Can a hard disk take 250 degrees?
More importantly, do you think hot works in addition to cold?

No it doesnt.

I wouldnt do that until you are about to bin the drive.

No point, the real solution is proper backups.

They arent all that bad.

Not when the drive isnt visible to the system.

You could try a logic card swap with an identical hard drive.

Since you're really more concerned about the next time, then forget about
fixing this drive.

The best way to be ready is to perform backups. If a drive fails, you're out
$50 or so for a replacement drive, but you can recover all of your data
quickly.

It seems to me I heard somewhere that wrote in
article .com:

I think you will find that most, if not all software only recovery
programs, will require the operating system to detect your drive as a
physical drive. I know this is the way I have written CnW Recovery.
Once software get get a handle on the drive, it can access sectors, or
attempt to access sectors, and then recover logical data. If it cannot
see the drive, then it cannot start.

There are also limitations when using a USB caddy, for instance it is
not possible to access S.M.A.R.T data using USB.

With specialised hardware and software, it is possible to diagnose the
problem further.

The suggestion of getting a replacement controller board is very
unlikely to help as all boards store details of the drive defects etc
that would need to be copied, recreated.

A specialist company is probably the only way forward. In the furture,
backups should be investigated!!

That's my feeling, too. It's probable, but not guaranteed, that at
least some, hopefully all, of the data remains on the disk. Most
recovery programs need some of the disk parameters to locate the data.
The specialist companies have other ways, such as direct reading of the
disk, to work around that.

Several years ago I recovered large amounts of lost data from my crashed
hard disk using GetDataBack, a pay-for with versions for FAT and NTFS
systems. I would NOT recommend trying it unless you can be satisfied
with only recovering parts of your data (I estimate I got about 85% to
90% back) AND simply cannot afford the cost of a specialist company.

GetDataBack scans the media directly, comparing against patterns that
indicate usable data, assembles what it finds, and makes it readable for
the user's decision on final recovery. The process takes time, a lot of
user involvement, and a willingness to fail. Not a happy option, but it
salvaged a lot of my personal data that I would not have been able to
recover from any other source.

Here's a segment from the Help in the program itself; it gives some idea
of what's involved: [www.runtime.org]

[Start]
GetDataBack will help you retrieve your files if the hard drive's
partition table, boot record, FAT, or root directory have been damaged
by a virus, accidental deletion, formatting, disk or power failure.

GetDataBack can even recover your data when the drive is no longer
recognized by Windows. It can likewise be used even if all directory
information - not just the root directory - is missing.

Advanced algorithms will make sure that all directories and
subdirectories are put together as they were, and that long file names
are reconstructed correctly. GetDataBack works on a partition level. It
restores one partition at a time.
[End]

There may be other programs that also scan the media directly; ISTM I've
used a similar one in the past, but that one is off my system now (too
many system and HD changes have gone under the bridge since then).

I want to stress that I'm not *recommending* going this route, but
simply letting you know there may be viable alternatives to solve your
problem.

GetDataBack works in a similar way to my CnW Recovery. It must have
access to the physical drive to read sectors. As I understand it, this
drive is not seen in any way by the PC, thus it is not possible to
read a sector. If you cannot get the PC to open a handle for instance
\\.\PhysicalDrive2 then one cannot read any data, and thus not do any
recovery.

It is a hardware issue.
