Beware of these data recovery mistakes
I’m going to wind up this series with three more recovery mistakes. I’m going to combine two of them since they deal with RAID arrays. However, the first one is a common mistake that many users make because they don’t realize the potential for disaster it brings.
• Saving recovered files improperly – One common mistake made when recovering files is saving them back to the same hard drive or media card. The hard drive may still have unresolved issues and saving the data back to it may cause further damage to the file. The file system may consider the lost data area as free for reuse. Your lost files may be overwritten before they are salvaged. Because of this, it’s better to save the files to a secondary drive, an external drive or other media, including DVDs, CDs or flash media. I’ve seen folks save back to the same drive, only to bring the drive into our data recovery service for retrieval.
• RAID errors – RAID is an acronym for “redundant array of independent disks.” Basically, this type of system, usually employed on servers, uses several disks to record data, allowing for redundancy. This is supposed to improve reliability; however, if a single disk fails and is replaced improperly, the data could be damaged beyond retrieval. There are several RAID configurations and each one has its own procedure for disk replacement. Because it can get confusing, many businesses contract a data recovery specialist for server recovery. This brings us to the last mistake. If a specialist is needed, the user must supply all crucial data about the server. That’s why it’s a good idea to keep all service manuals and other pertinent installation documentation. Without this information, the repair could cause even more damage.
Our data recovery engineers are trained in server and hard drive recovery and can help you to find all the necessary information for a successful recovery.
Laptop computers are becoming more popular these days. The smaller size and portability makes them the perfect computer for many families. When coupled with a wireless network, the laptop can be moved from the kitchen table to the living room couch very easily. This author even uses his laptop to work on writing assignments in the side yard, using the old picnic table for a desk in this outdoor office.
While the desktop computer is the workhorse of computing, the laptop continues to grow in popularity. I use a desktop for all of my “heavy lifting,” but the laptop is a constant companion on the road. To be sure, the portability of the laptop offers many advantages; it also is the source of several problems as well. Accidental, unintentional abuse frequently renders data inaccessible.
Because of its slender configuration, many people forget or do not understand that spinning platters and moving read/write heads still make up the most common laptop hard drives. Solid-state drives are more rugged and less susceptible to bumps and bruises, but the cost of the drive in relationship to size makes it too expensive for casual users’ machines. Therefore, most computers still use the more common platter-style drive.
The Data Rescue Center, a data recovery specialist based in Livermore, California, recovers data from hard drives that have been damaged by dropping or other inadvertent abuse. When a laptop is dropped, physical damage is likely. Notebook data recovery should be performed by a qualified data recovery service, such as The Data Rescue Center.
We all have heard the grinding sound that comes just before the crash of a hard drive. Unfortunately, you’ll never know when a hard drive will go bad. Sometimes it will crash right out of the box. Other times you may be able to use your hard drive for years before it starts to fail. But at some point it will fail. At that point you will probably need hard drive crash recovery.
The hard drive is the weakest points in your computer’s system. Unlike other components, it has moving parts. The motor used to put the hard drive in motion can fail. Your hard drive may fail due to problems with its head. This is the part that actually reads and writes the data on the disk. They can become askew or corrupted resulting in no data transfer. The plates or disks themselves can also become warped or not spin correctly resulting in a failure.
Outside sources can also cause failure a virus or other corruption in your system can make the hard drive unresponsive. Sometimes a firmware or operating system upgrade can trigger a failure in the hard drive as well.
In the event of a crash, there may be help. Hard drive crash recovery can take place. A Data Recovery Specialist can retrieve data still on the hard drive but is inaccessible to your system due to the hard drive failure. Data retrieved from a failed hard drive can then be placed into a new hard drive. It often results in a near new operating situation for the computer user.
At some point in time everyone will have to rely on data recovery information services to retrieve data they have lost during a hard drive crash. This is because all hard drives have a finite life-span. What this means is that no matter how well a person takes care of his hard drive, it is eventually going to fail and the services of a hard drive crash recovery company is going to have to be utilized.
However, this doesn’t mean that precautions can’t be taken to increase the life-span of a hard drive. Most hard-drive failures are due to one of two factors; viruses and heat. By addressing these two factors a person can greatly improve the life-span of their hard-drive equipment and decrease the chances that they will require disk file recovery services.
Viruses can be particularly damaging to a hard-drive and cause massive information loss. To combat this silent threat, an individual should have anti-virus software installed on their system. However, a mistake many people make is to install anti-virus software and not keep it updated. This can be as dangerous as not having anti-virus software at all. In fact, this may be even more dangerous because it lulls the person into having a false sense of security.
Heat is an even greater threat to a person’s hard-drive and the information contained on it than viruses. Heat build-up in a computer’s case can cause imminent hard-drive failure. This problem can be combated by making sure that all system fans are in working order and that they are free of dust.
Following the above tips can help a person protect their hard-drive and their data. By addressing these two common problems, a person can increase the reliability of their machine and avoid making unnecessary trips to a data recovery specialist.
Your data is important. Losing it, whether it is a million row database or just your music collection, sucks. Fortunately there are companies that specialize in getting data from corrupted and broken hard drives, thumb drives and other file storage techniques.
There are many different reasons for a storage device failure. On a hard drive, the reading heads(small arms that stick out over the magnetic platter and reads the data stored on it) could contact the platter, shattering the heads and damaging the platter. If you have damaged the circuit board on the inside of your thumb drive, it is still possible the data remains as long as the chips that store the data are still intact. If you are lucky, then the damage may not be physical at all. You may have just lost your partition on the hard drive, or accidentally deleted files. The good news with cases where the damage is not physical is that it is easier to recover the data.
Data recovery experts know how to get the data off of corrupted or damaged devices. While there is no guarantee that the data on your storage device is recoverable, a data recovery expert generally is able to extract some information. For a hard drive, this generally means transplanting the magnetic disk to a specialized device capable of reading the platter just like the heads could. For the thumb drive, the chips that store the data are desoldered from the broken circuit board and attached to a specialized reader. If the problem is purely software, then data recovery experts can use specialized software to check the integrity of the data.
To find a data recovery specialist who can handle your case, you need to know what type of device your data was stored on. There are specialized experts that focus on hard drives, CD and DVDs, tape drives, RAID arrays and more. Of course there are general purpose shops that have a data recovery expert who can handle many different types. Keep in mind that you will probably want to find a data recovery specialist that is nearby. Your hardware is already damaged, it is probably a bad idea to send it through the trauma of the mail. Usually a simple Google search is sufficient to find a nearby shop capable of handling your problem.
Data loss sucks, but it is easier to recover it now than ever before. Data recovery experts know how to recover information off of pretty much any storage medium. All you need to do to find one capable of solving your problem is to perform a search. Fairly large cities usually have a local shop capable of handling your needs. Ask around; see if anyone you know can recommend a good specialist. Who knows, you may get that database back yet.
