The Truth about Success Rates and Hard Drive Data Recovery, By Don Anderson

So your drive has failed and you've been researching data recovery. You keep noticing extremely high success rates on these data recovery companies websites. "Well, with success rates in the 90%+ range the data must be recoverable no matter what happens to it! If the data off my hard drive is recoverable no matter what, then it doesn't matter that I try a few local repair shops first that advertise such cheap prices or attempt some do-it-yourself techniques I find on the internet!"

Stop right now

First, I would like to make you aware that any real official hard drive data recovery company uses the same techniques and the same tools in nearly all the cases. Some may modify a technique because they are more comfortable doing things a certain way, but this doesn't change how the process works.

It's impossible to post an accurate success rate

"Why do they all do it then?"

That's an easy answer. They just need to lure you in. Once the drive is in their possession, it's easy to say your drive has fallen into the 6% unrecoverable category.

"But why can't you put a success rate on the chances of recovery?"

Because many factors come into play. If the drive has been powered on too much after failing this can lower the odds. If the hard drive has been tinkered with, banged, frozen, cooked, or dropped this can lower the odds. Nearly all cases that are received here have had other attempts from other computer companies or data recovery companies. It's impossible to know what they have done to it. Sometimes the drive is totally destroyed before it even arrives to us and there is no hope of recovery.

There is a location on the platters of the hard drive called the "System Area" that stores unique information that is needed to operate the hard drive. This can become corrupted, or damaged causing the drive to stop initializing. If the System Area cannot be repaired then the data cannot be recovered.

Another reason the drive can become unrecoverable would be from constant tinkering and excessive powering on after the heads are gone bad. In some cases the heads will grind away at the platters destroying any data that was on that drive leaving it unrecoverable. Usually the first place that is destroyed is the System Area since that must read first before the drive can initialize.

Even if the drive hasn't been tampered with you still can't give a accurate success rate without diagnosing the drive in person. Certain brands and models are less likely to be recovered. Slimline drives for example, have a terrible success rate. Some Fujitsu drives in macbooks have a horrible habit of damaging the service area and becoming unrecoverable. Older Western digital drives have major alignment issues lessening the odds as well.

"So when can you give an accurate success rate?"

After the drive has been received and diagnosed. Only then can an accurate assessment be labled.

Clicking Hard Drive data recovery

Also known as "the click of death". If you hear your drive clicking, clunking, beeping, buzzing, grinding, or making any abnormal sounds do not attempt to run any software on it or continue to power it on. Shut the drive off immediately and call a professional. Visit my sounds page to listen to some sounds that damaged hard drives make. Software cannot recover data from cases like these.

Beeping or buzzing hard drive data recovery

Beeping or buzzing is usually caused from heat or physical abuse like a drop. This is most common in Seagate and Western Digital notebook and portable drives, but can happen to any make and model.
In most cases beeping or buzzing is a good sign that you will need a level 3 recovery to replaced damaged heads from stiction or even a platter swap from a seized spindle. Do not attempt to run software on your drive if it is making these sounds.

Dropped Hard Drive data recovery

A huge portion of drives that come in for recovery are from physical abuse. When a laptop or external hard drive is dropped this usually causes some kind of physical damage. Most cases of dropped drives turn out to need head replacements, which is also a level 3 recovery.

Virus corruption or accidental format data recovery

When a virus has corrupted your operating system causing the system to no longer boot up this is considered a level 1 or logical data recovery. There is nothing physically wrong with the drive and a clean room repair is not needed in cases like this.

I/O Cyclic redundancy check data errors data recovery

A good indication that your drive has developed bad sectors and is starting to fail. A level 2 recovery is required in these cases. Do not attempt to run software on drives that are failing.

Disk read errors data recovery

Another indication that your drive is developing bad sectors.

Windows blue screen errors data recovery

If you are having I/O device errors, disk read errors, or your computer is blue screening there is a good possibility that your hard drive has developed numerous bad sectors. In cases like these the likelyhood of recovery is normally very good if the drive is not continuously tampered with causing more problems. Special hardware is needed to read bad sectors. Using software on drives like this will cause more damage. The only time software should ever be used is if the drive has no physical problems and the data loss is stricly a logical problem.

Server RAID data Recovery

RAID failure from a HP or Dell server

it's very important to stop at once, label the drives in the correct order of the ARRAY and contact a professional. Normally one or more drives have failed bringing the entire RAID down. These can be very complicated to recover from depending on how many drives are in the ARRAY and what type of damage has been done. After the repair has been completed the entire ARRAY must be rebuilt much like a puzzle piece before the data can be recovered.

Secure Erase download below free hdd erase software
User data is left on disk drives removed from computers and storage systems, creating a data security vulnerability that many users are unaware of. Recent Federal and state laws requiring secure erasure of user data expose companies to fines of $250,000 and responsible parties to imprisonment for 10 years. Complete eradication of user data off drives can be accomplished by running data Secure Erasure utilities such as the freeware "HDDerase" downloadable above.

It executes the Federally-approved (NIST 800-88) Secure Erase command in the ATA ANSI standard, which is implemented in all recent ATA drives greater than 15-20 GB.
