Nowadays, loss of data can cost a business millions. Data is a critical asset and organizations must be able to deal with natural disasters, government compliance, database corruption, component failures, and human error.
Businesses generate and maintain vast amounts of data, including details of customers, partners, inventories, products and services. What will happen to your business if all that data is lost?
Can your business survive a catastrophic event such as the 9/11 bombings or hurricane Katrina or the recent devastation seen in Alabama and Mississippi? Disaster recovery can be defined in many ways because there are many different types of disasters that must be addressed.
This simplest and most common is a system failure, referred to as a system failure. In this case, the hard drive and its contents are preserved, but the system that housed and used the data is no longer functional.
The second and more difficult situation is a hard drive failure. Recovery from this experience can vary from full to none. Customers must have reliable backup to insure 100% recovery.
The third is complete loss of the device due to either a catastrophic event or robbery.
Levels of Hard Drive Recovery
These levels relate to the complexity, the experience and sophistication required to get you access to your data, and include hardware and logic failures.
Level 0 data recovery is commonly referred to as “restoring.” The customer must have a current back-up (or copy) of the data, that can be used to restore the data on the computer. This can be performed by you (the customer) or by KK Enterprises.
Level 1 data recovery is when a hard drive is recognized by the system but the system is unable to access the files needed. Causes include mistakenly reformatted hard drives or deleted files, deleted, damaged or corrupt partition structures, and virus or spyware infections.
Level 2 data recovery is when a drive appears to your computer system as corrupt, as incorrect drive size, or as incorrect model numbers. KK Enterprises utilizes special equipment to rewrite the drive’s firmware, and recalibrate and program the drive so that the files can be recovered.
Level 3 data recovery is when a clicking or other unusual sounds are heard coming from drive, the platters aren’t spinning or the drive isn’t recognized by the computer. Part of the process requires work inside of a clean room to remove covers and seals to repair a drive head stuck to a platter surface, realign heads, clean platter surfaces or replace components on the printed control boards (PCBs). This level also includes imaging equipment to perform a sector-by-sector image while bypassing bad areas.
Level 4 data recovery is when extensive procedures are done in a clean room, including replacing read heads or transplanting platters, then mounting and precisely aligning the parts. This level of work is needed when the platters are damaged from excessive heat (fire), or the spindle motor seizes (is frozen) or is contaminated by foreign materials, including water.
