The worst thing that can happen to most laptop users, aside from the loss
of the whole laptop, is hard drive failure. The hard drive holds all of your
data, files, and all your e-mails and contacts if you use Outlook, Eudora,
or any other non-portal based e-mail. But I'm sure many more laptops have
gone to the recycling facility with live hard drives than dead hard drives.
If you have any files you value on your hard drive that aren't backed up,
you should invest $10 or $15 in a USB shell and attempt to recover the data.
Hard drive data recovery is thought to be an arcane art, requiring expensive
equipment and a high level of technical skill, but all of that only comes
into play if the onboard electronics or the motor have failed. In that case,
the drive platters are removed from the metal case in a special clean room,
and the data is recovered by reading it off on a universal reader.

Most laptop owners are still very foggy as to where their data resides and
consider the whole lower part of the laptop (everything except the screen)
to be part and parcel with the hard drive. In reality, laptop hard drive
are 2.5" wide, about 4" long and about a quarter inch thick. They weigh a
couple of ounces, and can normally be accessed by removing a single screw
from the laptop, as shown above.You should always unplug the laptop and remove
the battery before attempting to do any repair work. I'll admit I left the
battery in here, because I knew it had been stone dead for some six months
or more, since the AC adapter died. After removing the single screw, you
can see the 2.5" laptop hard drive installed in its cage. This hard drive
is an IBM Travelstar, perhaps the most common hard drive used in laptops
the past couple years. Because it's an older laptop, there's no shock mounting
for the drive, little rubber washers that have become a popular way to partially
shield the hard drive from the vibrations that can cause head crashes, in
which case you can't recovery the data with a million dollar lab.

The next step is to remove the whole cage from the laptop, which involves
pulling back on the cage to free the drive's IDE interface from the laptop
connector. You can see to the right that the drive cage is held from lifting
by two metal tabs, and that the screw that held the plastic lid on the drive
bay went all the way through and secured the cage in the laptop. That's all
that held it together, one screw, and it's a typical arrangement. It turns
out that removing the old hard drive from the cage, once it's out, is generally
a bigger job than removing the cage from the laptop, because there are four
screws involved and they are often overtightened and strip when you try to
remove them. But it's not necessary to take it apart any further if all you
want to to recover your old files.

To the left, I'm holding the new USB 2.0 interface that came with the $14.95
Sabrent hard drive enclosure
I
bought from Amazon for $14.95. The interface is really all you need to
gain access to the old hard drive, if it's healthy, and recover your data.
The kit comes with software from Mac users as well as Windows based machines,
but modern operating system versions don't even require the software. They'll
just find the new USB hardware when it's plugged in, recognize that it's
a hard drive, and allow you to recover your files as long as the file system
types were compatible. I'm holding the interface card over the aluminum enclosure
in which you could install the drive if you wanted to use it as a permanent
external hard drive.

But when I started taking the screws out of the cage, three out of four fought
me and the fourth stripped, despite the fact I was using a high quailty screw
driver. It would be easy to bend and break the remaining tab off to remove
the cage, but why bother, when the only point of the job is to recover some
old files? So I plugged the interface on (to the right), then set the whole
thing down on my table with the new laptop and plugged it into the USB 2.0
port. You can see that the little green LED on the drive is lit and active,
if you have good eyes and a better imagination.

Immediately after plugging in the USB cable, Windows XP picked up on the
drive, and asks what you want to do with it. Choose "View with Explorer"
and you'll gain access to all of the old folders, drag them onto your new
laptop hard drive, and your data recover job is complete. Well, after you
burn the recovered files on a DVD it will be complete, and you won't face
the worry again. If the LED doesn't light up, you could be plugging the USB
into an old port that doesn't source the 500 mA required, or the interface
could be bad out of the box, or the drive could really be dead. If you don't
hear the drive spin up, you can try picking it up gently, a few inches over
the table, and try rocking in slowly to see if you can feel the centripetal
force of the disk spinning.
