Fixing a hard drive?
    #6166871 -

Does anybody here have any experience in recovering data from a dead hard drive?

One of the professors at school lost a whole bunch of data when a hard drive crashed. The head knocks when it tries to operate. No way of telling if the platter is damaged except to open it up.

He seems to think the best way to do the recovery is to take the platters out and move them over to a new hard drive of a similar or identical model.

Buh?

If the data isn't critical, he's probably right and it would be a fun project. But, with my limited understanding of hard drives, I predict it won't work unless he has a clean room at his disposal. Especially not if it's a newer high density drive. If the data is critical he should contact a professional recovery company like Ontrack.

What's the difference between a clean room and a flow hood?

How much does OnTrack cost?

It costs a buttload, oh man!
That is exactly the method that professional services use, and they do it in a clean room. Clean room means perfectly clean, sterile conditions. Not a particle of dust or anything. People in space suits who take decontamination showers.

I have used drive savers in the past. They are very good, but expensive. One of my clients got about half the data back for around $900. Another client got 100% of the data back for $2300. www.drivesavers.com I'm not affiliated with the company, just happy with the service they provided. (Turn around time was under three days.)

None essentially.

I have successfully performed platter migration sans any clean room antics on very old hard drives. In fact, I have operated hard drives under full load with no cover in my bedroom. I understand that the newer the tchnology is the less likely this will work as the heads get closer to the media and the magnetic density of the media gets higher; both of which imply that the relative size of a speck of dust becomes more and more relevant.

I remember reading a description in an old version of Repairing and Upgrading PCs that stated that a hard drive travelling over a platter is something equivalent to the empire state building set on it's side flying across the utah salt flats at mach 4 and only 3-5 feet off the ground. If you say that a speck of duct is equivalent to a Volkswagon Beetle at that scale you can imagine the catastrophe that results when the empire state building hits the Beetle.

I too, have used the freezer method. It tends to work best for drives that work for a few minutes and then fail which indicates physical distortion via heat.

I also remember the good old days when the layer on platters would become semi-liquid during use and then solidify onto the parked head when shutdown thereby requiring the user to sharply rotate the drive or smack it on a surface to free the head.
