In this video we show you an actual case that was sent in to us for data recovery. It is a great illustration of how severe the damage can be when a head failure occurs, and we explain why the data cannot be recovered in these situations.
Regardless of what you may have heard or read, when the magnetic coating on the platters (the area that actually holds the data) have been turned to dust, there's no way the data can be recovered. Imagine writing your name on a piece of wood and sanding it off, then try to imagine repairing the sanded area to restore your signature, it's physically impossible. The same thing occurs with hard drive platters.
Hard drives are extraordinarily complex devices. Any imperfections in the platter or read-write heads can cause the drive to fail. If a head failure is severe enough it can score the platter surface as illustrated in this video and render the data unrecoverable.

Some companies will tout that they have a 95% or better success rate when it comes to hard drive and RAID data recovery services. The truth is, they are either extremely lucky or they get very few jobs in. Most data recovery jobs are either recoverable or unrecoverable before we even receive them. In cases like this when the hard drive platters are severely damaged, then there's nothing we or anyone else can do. Has nothing to do with our capabilities when it comes to data recovery.
If we had 100 jobs come in every week, and 99 of them had scored platters, our success rate would only be 1%. That's not realistic, and not an indicator of capability.
On average, if you really ask the companies that know what they are doing, you will find that about 15-25% of the drives that arrive are not recoverable from the start due to either platter damage, data corruption, or failed prior attempts that have exacerbated the problem.
If you need data recovery on a failed hard drive or RAID array, just make sure you do your homework and verify that the company can actually recover data successfully. Most won't charge you any attempt fees unless they can recover your data.
At ACS Data Recovery we never charge an evaluation fee, and the only time we ever charge attempt fees are in cases where a drive has already been opened prior to our receipt, or in complex RAID arrays.
