Successful Data Recovery MUST “bypass the computer’s operating system software (Windows) and built-in ECC algorithm.”


Most local companies cannot afford the highly specialized equipment to properly handle a data recovery project. They rely on inexpensive imaging software which DOES NOT bypass the computer’s operating system software (Windows) and built-in error correction code (ECC) algorithm. Their type of “data recovery” software will physically stress your already fragile hard disk drive with intensive read processes potentially resulting in the complete failure of the hard drive. Their approach to data recovery can quickly move you to requiring the “last resort” – hard drive disassembly in a clean room. Data recovery projects needing this final level of expertise end up costing upwards of $6,000.

At Computer Warehouse of North Carolina in Greensboro, we have the expensive hardware and software that industry leaders use to handle sixty percent of all hard drive failures. The forty percent of data recovery jobs we cannot handle should always be sent to the industry leading data recovery experts at one of the two companies below:

Make the first step in your data recovery project is to get free analysis of the state of your hard drive from Computer Warehouse of North Carolina in Greensboro. We own one of the DeepSpar Data Recovery imaging units. Unlike our local competitors, our imaging hardware and software solution combines several critical capabilities to increase the odds of a successful data recovery. Sixty percent of the time, we will be able to handle the data recovery project right here in Greensboro saving both time and money.

Be sure to ask your data recovery specialist if they use the DeepSpar Data Recovery imaging solution

During a data recovery project, the already fragile hard disk drive will often stop responding to operating system software read request. The imaging hardware we use does a hardware reset to the drive when it stops responding minimizing damage from head-clicks. Unproductive head-clicks can permanently damage your drive if they are not kept to a minimum. Inexpensive software only solutions can permanently damage your hard drive leading to the drives disassembly in a clean room to successfully recover the data.

More about data recovery

Proper data recovery involves as many as three phases; mechanical or electronic hard drive restoration, disk imaging, and data retrieval.

Drive restoration is required if there is any physical or mechanical damage such as failed heads, electronic failures from circuit boards, or a firmware failure. Drive restoration is required in about 40% of all drive failures.
Our DeepSpar data recovery system addresses the remaining 60% of drive failures even if there is some minor physical degradation due to normal wear and use. In these cases, the wear is severe enough to interrupt operation in the native operating system mode but has not degraded to the point where hardware disk imaging is unable to read, retrieve, recreate, verify, and repair the data from severely compromised disk sectors.

Our DeepSpar data recovery system addresses the remaining 60% of drive failures even if there is some minor physical degradation due to normal wear and use. In these cases, the wear is severe enough to interrupt operation in the native operating system mode but has not degraded to the point where hardware disk imaging is unable to read, retrieve, recreate, verify, and repair the data from severely compromised disk sectors.

These unstable drives always have high read error rates, read instability, and require technologically robust hardware and software manipulation in order to successfully perform a complete data recovery.

“For example, wear in the actuator bearings causes slight deviations in the distance the arm moves across the platter. As a result, the current that was once required to move the actuator to a certain track is no longer sufficient to move the arm precisely. Read errors can also be caused by dust infiltration into the disk drive over the course of its life, which may make the read process electronically noisy. The important point is that failed drives tend to have read instability no matter what the reason for failure.”

Because of how the operating system, BIOS, and firmware interact, it is impossible to have a complete data recovery of the hard drive without specialized hardware and software controlling the data recovery process.

READ INSTABILITY cannot be handled by the operating system’s software. Therefore, software only disk imaging solutions which run on top of the system’s operating software are not very effective. In fact, without hardware in place to guard against intense read operations, further damage to an unstable drive can result. For example, Windows operating system software reads each disk sector presuming there is no data corruption. If a read request returns an ECC checksum error then the read request is repeated several times causing additional physical stress to the already unstable drive. Eventually, a read timeout occurs and an ECC error code is sent to the display informing the operator that a read error has occurred. The read timeout error handled by the operating system is incorrect 90% of the time because the operating system is programmed to assume the data is readable. Fortunately, most of the bytes in the sector are readable, but only if you can work around the computer’s operating system.

In order to access the readable data, the system software and BIOS must be bypassed with specially written software code running on specially designed hardware. The DeepSpar imaging solution is able to use ATA read commands that ignore the ECC status and is still capable of reading the drive error registry. Being able to read the drive error registry allows DeepSpar to employ different algorithms to handle the different types of errors. For example, if our imager reads a sector 10 times and a particular byte returns the same value eight times then that value is statistically likely to be the correct one.

Unfortunately, most imaging tools use the computer’s operating system software to access the data drive. So reading the same sector the DeepSpar imaging system is able to read only results in another ECC error code resulting in no data or incomplete data written to the newly created image.

DeepSpar Imaging Hardware minimizes additional damage.

When read timeouts start to occur the hard drives firmware becomes unstable resulting in read instability. Read instability causes the drive to stop responding to the operating system software read request. To resolve this problem, the IDE reset line must be under the control of independent hardware and software to bypasses the computer’s operating system. Otherwise, the only solution to an unresponsive hard drive is a manual reboot of the system during the data recovery process. I’m sure you can imagine what results when the system keeps freezing and the operator keeps rebooting the computer.

DeepSpar is able to avoid constant rebooting by issuing a hardware reset command even when a drive ready timeout occurs. This software reset is the least taxing process on a non-responsive hard drive versus the repower and reboot method. A software reset minimizes physical drive activity reducing additional wear to an already fragile drive. This reduces the risk of drive self-destruction due to unnecessary repetitive head-clicks or reboots avoiding the major danger with read instability.
