A Quick Data Recovery Guide

Put your data recovery knowledge to the test with our data IQ quiz.

Data recovery, clean rooms, and hard drives are terms we toss around at Secure Data Recovery headquarters. You might only use a computer only a few times a month or you are never far from it. But when something goes wrong, it’s important to know how your data is stored and how your computer works. Let’s put your knowledge to the test! Answer these questions to find out your data IQ. Read the question and think for a second before reading the answer.

1. What is Data Storage?

Data is stored in digital memory, that records data in the form of binary 1s and 0s. This is CDs, DVDs, hard drives, (random access memory) and more. Data media types constantly evolve.

2. What Types of Data Storage Are There?

Modern computers store their data traditionally either in RAM, which loses data without electric power, or stacks of disks in a hard drive where data is permanently written (until deleted or overwritten). On a network, storage is usually in the form of network attached storage (NAS), or a storage area network (SAN). A NAS is a single storage device such as a dedicated file server. A SAN is a group or smaller network of storage devices that communicate with one another to store data in blocks.

3. What is a Data Recovery Clean Room?

A clean room (or cleanroom) is an environment kept free of contaminants such as airborne particles or chemical vapors. For computer data, read/write heads hover just microns above the surface of the disk, and contamination could cause misreads or loss of crucial data, or failure of the drives. 1 micron = about 0.000039th of an inch. Clean room data recovery is important when the drives have to be opened and the internal disks are exposed to air.

4. What is Cloud Storage?

This is often a free limited space (5GB comes free with iPhones, for example) or paid service where a hosting company stores client data across multiple servers (or locations) accessible via the Internet. It’s different than storing the data on the device itself.

5. What is SSD?

SSD stands for solid-state drive, and uses flash technology as an improvement over hard disks that had moving parts and tended to wear out eventually, needing replacement or hard drive repair. SSD also sometimes needs repair but data recovery is something best left to experts in the technology.

6. What is backup and recovery?

Backups are copies of data that are made regularly and stored separately so that the data can be restored (recovered) in the event of disruptions like viruses or hardware failure.  Data recovery services provide this process for other companies and individuals. As they are different operating systems, backing up Windows data may require different partitions and software than data recovery for Macs. If you couldn't answer more than a couple of these, we hope this quick data recovery guide has increased your data IQ. Would you like to put us to the test?
