Concerned About Data Recovery?
Data is stored in various storage media such as magnetic tapes, hard disks, floppy disks, etc. With time, the data stored in these medium might get damaged due to many reasons. Data recovery is a process to recover the lost or damaged data which has become inaccessible or corrupt.
The data stored in various storage mediums may be of great importance to you or the organization for which you work. Any damage or loss of data might cause a serious loss to you or your company. Thus, certain data recovery measures can be highly useful in situations where such a mishap has occured
Data gets lost or damaged in many ways. The cause can be a virus attack or improper storage of data in the data storage medium. The cause can also be a simple accidental erase, or a natural disaster such as flood, wind or earthquake. Whatever may be the reason, there are many techniques to recover the lost data.
Simple data recovery options involve data recovery via simple hardware or software. The most complicated data recovery cases require a data specialist. Let's take a closer look at some data recovery examples. Optical drives suffer from damage caused by small scratches and nicks on the underside of the DVD or CD. Options for recovering damaged data with these type of drives frequently will involve two steps or stages. The first stage deals with filling the nicks, and the second stage deals with sealing of the surface of the nicks. Hard disks are prone to physical, logical, and/or mechanical damages. There can be a number of different data recovery measures applied to the hard disk depending upon the fault. For example, if the Printer Circuit Board (PCB) of the hard disk is damaged while the platter, on which the data is actually stored, is intact, then the solution is to replace the PCB of the hard disk. However, if the data stored on the platter is damaged, then a Hex Editor will help find the exact fault location. Data can also be recovered from errors in the RAID configuration. For example, in RAID 0 configuration data is stored in two different physical drives. Through certain data recovery measures, it is possible to recreate the RAID array and recover the lost or damaged data from each drive, and then place the data back at its original location. You must be wondering how lost data can be recovered when it's supposedly gone. Actually, when a file is deleted, only the index that points its actual location gets deleted. The file, as such, is many times left untouched. So, if everything goes according to plan, the recovery method overwrites this location, and the file gets recovered. Prevention is always better than cure. Rather than getting the data lost and then having to deal with recovery measures, its better and less stressful to adopt some prevention measures. Data recovery plans usually contain these preventive measures. Taking frequent back ups of the data is one of them. Thus, following the preventive measures, and using data recovery plans should they become necessary, can help guard your stored data againt untimely loss.
