Examples of Data Loss Situations - Hard Disk Drives

Recovery from physical and logical damage due to mechanical and electrical failure, software corruption or human error.

• Computer will not boot
• Hard disk crashes
• Accidental reformatting of partitions
• Accidental deletion of data
• Applications are unable to run or load data
• Corrupted data
• Fire and water damage or crushed
• Hard disk component failures
• Inaccessible drives and partitions
• Virus
• Media surface contamination and damage

Recovery Process

Each recovery case begins with an evaluation to determine the potential for recovery and to provide a firm price-quote for your review. The initial diagnosis determines whether the media is accessible to our lab equipment. If so, the first priority is to create a raw image of the data on Sherlock Data Recovery Services media so that logical analysis can determine the nature of the data loss situation. If the media is inaccessible our facilities will test the components and closely examine its internal health to determine the extent of physical damage.

Recovery of crashed hard disks often involves replacing failed or damaged components in a clean environment and using specialized hardware and software tools to create the raw image. Failed components typically include electronics, read/write heads, head assemblies, magnets and drive motors.

Logical recovery uses the raw image by examining the low-level data sectors and determining what fixes to filesystem structures are needed to get access to the important data. Sometimes the existing filesystem structures are missing or damaged so much that data has to be extracted directly from one or more fragments of the raw image.

Sherlock Data Recovery Services Data Recovery programmers have created a full set of software tools used by our experts to analyze, fix and recover data from raw images of all operating systems. Once a recovery has been successfully performed, file lists are created and data validity is checked.

Recovery Pricing for Single Hard Drives

Each data recovery case has its own unique characteristics. Based on the high volume of cases handled by Sherlock Data Recovery Services we can classify most single hard drive recoveries into two broad categories : External and Internal.

Pricing for Single Hard Drive Recoveries.

The actual price of any case is determined by two main factors:
The cost of components.
The total time spent on the case and what proportion of the work is done by junior, intermediate or senior experts. In turn, the amount of time and seniority of staff needed are affected by:

 The File-system type. (Various Windows systems such as FAT32 and NTFS, ext2fs, xfs, reiserfs and jfs filesystems)
 The degree of file-system rebuilding required. This is the amount of logical repair work required for an external recovery or as the follow-up steps for an internal recovery.

Other factors affecting the price quote are:

The historical success rate on a certain type of data loss situation on a particular model. Note that there is no charge at all if the data cannot be recovered; hence the costs involved in attempting the recovery are borne at our risk. Where we enjoy a higher probability of success (and thus lower risk) the price quote may be lower than those cases with a lower probability of success and higher risk.
Significant research and development is required to keep up with the technological developments in the drive industry. Pricing for newer data loss problems on newer models will be higher than the pricing for mainstream problems on more common models.

Turn-Around Data Recovery Time

Sherlock Data Recovery Services has geared its entire service to recover your data as fast as possible. When dealing with such a wide variety of problems, estimating time before the problem is diagnosed is difficult. That is why, each recovery case starts with an evaluation.

The evaluation is started immediately on receipt of the media and generally takes 2 to 24 hours to complete. The process involves several hours of work and testing. (Mirroring alone may take up to 24 hours of computer time with extensive re-tries for badly damaged devices.)

Complete recovery turn-around time including analysis and recovery is usually between 1 and 5 days. Some severe cases can take considerably more time.

Our hours of operation are 9am to 7pm EST Monday to Saturday. If you have an emergency situation, we have technical staff on call for weekends and after hours in all locations.
Call (800) 267-4712 or in New York (212) 249-9888 or in Pennsylvania (570) 895-4340

Time estimates are based on procedures and expertise required to recover the data you require. You are not charged by the hour. A firm quote is provided for your approval following the evaluation.
