These frequently asked questions (FAQ’s) are a drop down list of questions and answers commonly asked regarding data recovery. Hopefully you will find the answers you are looking for here. If not, feel free to contact us. We are always happy to help!
What is data recovery?
Data recovery is the process of recovering data from the damaged media by the recovery experts. The damage to the storage media can be categorized in to physical damage and logical damage. The data is retrieved back by recovery experts after determining the type of the damage caused to the storage media.
What is the probability of data recovery?
Data loss is a very critical situation and must be handled as such. No matter what the cause, data can usually be recovered. In recovering the data from a failed hard drive, zip disk, tapes, floppy disk, or other storage media, there is around a 98 percent chance of recovering the lost data in its entirety. Usually, some if not all the data is recoverable. The probability of a successful data recovery is reduced to a great extent if the damaged device is mishandled or any attempt made personally to retrieve the data. Launching unnecessary programs, restarting the computer or any activity taking place on the damaged hard drive may make the lost data irrecoverable forever. Using a conventional data recovery technique or handing over the damaged device to a reputed data recovery company avoids wasting time, effort and money resulting in quicker data recovery with a higher probability of success.
How long does the data recovery process take?
The data recovery process can take as little as 2 to 5 days or up to 3 weeks depending on the severity of the failure and if donor drives are needed.
What is a partition? Can the data be recovered from a deleted partition?
Allocation of memory in different sections is called a partition. Each partition made is like a separate disk drive. Partitioning can be very useful when the user wants to use more than one operating system. When a disk gets formatted, the partitions are erased, or rather, the partition table which stores the information is. The partition is not actually deleted. The data can most likely be recovered by using recovery tools which copy the data present in the erased partition to the new destination drive.
What is a head crash?
A head crash is when the read/write head of the hard disk is damaged. This usually occurs when the head is contaminated by dust particles or if the head gets sudden contact with the media surface. A head crash damages much of the data present on the hard disk drives. When there is a head crash, both the head and the disk need to be replaced. It is important to operate on the hard disk drive in a clean-room environment, because dust or even smoke particles can damage the head of the disk beyond repair causing permanent data loss.
What are causes of data loss?
Data loss is the unexpected or accidental loss of data stored on the storage media. Data loss can occur because of software corruption or hardware malfunction. Some common issues that can lead to data loss: -Power surges -Software corruption or malfunction -Hardware or system failure -Natural disaster -Improper shutdowns
What is meant by Hard Disk De-fragmentation?
Disk de-fragmentation is the process of rewriting the parts of a file to increase the speed and recovery process. When files are updated, the computer saves the updates on different spaces on the disk, which often results in slow access times. De-fragmentation optimizes the storage locations, creating faster access times while creating more usable space on the disk.
What is booting?
Booting is a process in which the system starts while checking all the components present in the system. If all is well, the system starts. This is called POST, or “Power on self test”. If the system is not booting then all components must be checked. A good place to start is to check whether they are connected properly. If a system is not booting, it could indicate a recent hard disk failure. No attempts should be made to repair the system yourself if the data is important.
What to do if the hard drive does not spin up?
When the computer is switched on the hard drive must be recognized by the BIOS. When the drive does not spin up the power connections and data cables must be checked properly to insure that power is being supplied properly to the disk and the cables are attached in the correct positions. If all appears to be well, the problem most likely resides in the drive and must be taken in for data recovery immediately.
