Data Management has become a crucial part of every Corporation’s and small Business’s infrastructure. A comprehensive Data Management Plan should define how the data will be archived and stored and who will have access to the data. These are the most import parts of a Data Plan as approximately 44% of all Data Loss is a result of Hardware Malfunctions or Failure and about 32% of Data Loss or Corruption is a result of human error. Therefore it is critical to understand the expected life spans of hard drives, workstations and storage serves and have a comprehensive update plan to prevent critical data loss due to hardware malfunctions. Since the next greatest data loss occurs from human error, having a personnel data management plan including who has access to critical data and who is responsible for backing up mission critical data can reduce the risk of a data disaster loss.The most critical part of preventing a Data loss Disaster is implementing the proper data storage devices needed for your business needs.

Recovering data from a failing hard drive is not advisable. Attempting to do so can result in complete loss of your data. If your hard drive is slow to access, slow to copy data to or from or has folders that are not accessible or empty all indicate that the drive is falling. The best course of action is to shut the drive down and call one of our data recovery Techs. All hard drives are forensically imaged for any data recovery services. Our Forensic Imaging hardware has a unique ability to recover bad sectors. Few imaging devices or software can deal with massive sector failures. Our hardware is adjustable for multiple attempts to read bad sectors resulting in a very high success rate of recovering data from those sectors. Multiple attempts to read bad sectors with our hardware will not shut down the hard drive due to bad sector limitations of the SMART feature of the Hard Drive. Forensic imaging is the byte by byte imagining of every sector of the client hard drive. We have successfully recovered many hard drives with over 800,000 plus bad sectors. We provide Certified Forensic imaging for eDiscovery cases, Forensic Data Recovery and Forensic data imaging of all make and models of hard drives, raid arrays, flash drives, and micro hard drives.

External hard drives are generally portable SATA hard drives or SSD Flash Media Drives connected to the computer via USB, FireWire or Thunderbolt.
We also provide raid data recovery for any brand of external hard drive configured is a raid array. Most external drives set in a raid array are usually configured in a striped, raid 0, array or a mirrored, raid 1 array. Data Recovery of external hard drive raid arrays are generally recovered within 12 -24 hours of receipt of the drives.
The most common external hard drive data recovery issues come from corrupted firmware modules or motor spindle seizure. Corrupted firmware generally occurs when the external drive is dropped while running or unplugging the drive before a read and write operation is completed. Spindle seizure usually occurs when the external drive is knocked over or dropped. This type of data recovery will require a Platter exchange and a clean room recovery. Either recovery case will cost our same Flat rate price. We recommend, when using an external drive, that you lay all stand up external drive flat on your desk to reduce the chance of the external drive being knocked over.
External hard drives were designed to backup data from your pc or server. By moving your data from your pc to the external drive you have made the external drive a primary data storage device, without any backup. Backing up data to multiple external drives is the only safe method of securing your data. Cloud storage of your data is another method of backup. Cloud storage should only be considered as a third backup as data can be corrupted in the upload or download transmissions.

Raid Data Recovery - Raid Hard Drive Data Recovery - Raid Array Data Recovery
Raid Hard Drive configuration RAID (Redundant Array of Independent Disks) is the combining of two or more hard drives working in unison to gain greater levels of performance, redundant reliability, and or to create a larger hard drive volume sizes. In the past this type of configuration was generally used only by large companies. Today, many small business and home users are finding an ever increasing need for servers and mass external storage devices to store there ever expanding data needs. When multiple raid configured hard drive arrays fail, special software and hard were is needed to successfully recover your data.
We provide Worldwide Data Reconstruction for all Raid levels. If you have a raid array fail in your SAN Server, Raid Server or NAS server do NOT attempt to rebuild the array unless you have a complete backup off all the data, separate from the Failing Raid array. Attempting to do so can corrupt data if not completely loose your data.
Most Server and NAS arrays are built using drives that were from the same lot. When one drive fails there is now a high probability of other drives in the array will fail in short order.. If other drives in the array fail during the rebuilding of the array you will most likely loose your data. If you do not have a complete and current backup of your data from the array then the best choice is to power off the server and call one of our raid specialist. We have found that most of our Corporate Clients and Business Clients are relying on their raid array as to sole source of their data backup based on the redundancy of raids. This is a practice that will lead to disaster. Raid Arrays fail for many reasons as do single hard drives, CDs, and DVD,s Flash Drives and SSD Drives, Cloud storage. Protection from data loss can only be accomplished by multiple copies of the data and understanding the life expectancies of media storage devices. During the past year we have found many Raid array recovery clients with a replace hard drive from a different manufacture or model number. This is another practice that will put the drives out of step which can cause slower read and write speeds and possible lost of the array.
Raid arrays are configured in raid levels based on the performance and redundancy that is required for the application. Raid levels vary from hardware arrays and software arrays Raid Levels consist of Standard, Non Standard Raid levels.
We provide advanced raid data recovery for hard drives configured in the following raid levels: configured in Raid 0, Raid 1, Raid 1 – 0, Raid 10, Raid 3, Raid 4, Raid 5, Raid 6, ZFS Raid, Raid 5e, Raid 5ee, raid 15, Raid 6E, Raid 1.5, Raid 7, Raid-DP, Raid S, Matrix Raid, Raid-K, Raid-Z, Raidn, Linux MD 10, IBM ServeRaid 1E, unRaid, Drobo BeyondRaid, Nested Array, Hybrid Array, Raid Data Reconstruction Recovery from hard drives configured in Standard Raid Levels Raid 0, Raid 1, Raid 2, Raid 3, Raid 4, Raid 5, Raid 6.

Raid Array Issues - Raid Array Recoveries
Raid array failure for most corporate users is generally a minor several hour inconvenience as they are more likely to have a disaster plan in place to deal with raid array failures. Large corporations generally have the resources to have multiple servers so that ALL their data is not concentrated on one server. They will usually have multiple up to data backups and possibly a backup server ready to go on line.
Having a raid array failure or a single drive failure is a disaster for most home users and small to medium size business users. Panic sets in as you see your entire digital life gone or your entire business shut down. What you do next can determine if this disaster turns into a Major Disaster or a Catastrophic Disaster.
Remove the server array from the network and Shut the system down. This includes an active array with just a single drive failure. Do not attempt to rebuild the array unless you have a good backup copy of all your data including the most recent files. Remove all of the drives from the array. Build a new array with new drives and start rebuilding your array from your data backup, even if the backup is old and out of date. If your raid array needs to be recovered you will already have the server and your company up and running. Once the recovered data is back you will simply be updating the array. Even if you have a complete and sound backup of the array, rebuilding using the remaining good drives may result in corrupted data, lost files or failure of other drives in the array. With most businesses, getting the company back up and running and recovering all the data is most important. Buy following the previous steps you have the server up an running in the quickest amount of time and you have the failed array secured so no other damage or data loss can occur.
I know this goes against what older IT administrations and Techs were taught. We have a combine 57 years experience building, recovery, maintaining and implementing raid arrays on servers, NAS devices, SAN Servers and DAS Servers. This is not how we were taught when it came to recovering a failed raid. Back when, we were limited to the software and hardware that was available to use for bad drives, like CheckDisk, Fsck, Spinrite, all of which are destructive programs. Destructive because they re write data on the hard drive attempting to correct errors in the MTF or Journaling systems or moving data from a bad sector to a good sector sector. With an active failed raid array, with no backup, copying the data or cherry picking the data was the only choice then attempt to add a new drive for the failing array and attempt to rebuild the array for several hours or days. How many arrays have you spent hours on a rebuild, only to have another drive go and the array fail?
Why Not copy the active data from a failing raid array or replace a failed drive and rebuild? The main reason is that when the array was first constructed at the factory or by an IT department, all the drives used in the array were the same make and model drive. All the drives were most likely purchased at the same time from the same location and most probably were all manufactured at the same time and are from the same lot. If one drive from the same lot fails, there is a very high probability that other drives will shortly fail with the same problem. At this point why the drive failed is not of concern. Your only concern at the moment is to protect the integrity of the data on the drives. If you start a rebuild and another drive fails you may corrupt or loose data on the array. The only safe course of action is to remove all the drives from the array and have each forensically imaged with forensic hardware and software designed for data recovery and having the ability to deal with bad sectors.
Bad sector failure is the second major concern when attempting to rebuild a failing array. Greater density has been gain on the hard drives by the compression of tracks and sectors to produce greater capacity on the same size platters of 20 years ago. Failing sectors are now more critical then in years past, especially when dealing with multiple drives in a raid array.
