As this is the information age, most firms use other forms of media to store their valuable data. However, there is one form called the tape drive that are still used by many organizations worldwide. The notion of tape data recovery still entails mystery and how it is to be done. This type of recovery is to recover any data that has been lost on a tape.
How can a tape cartridge be damaged? It can be damaged from smoke, dropping into the water, or simply just dropping from high levels. It can also be damaged from the exposure from the sun, extreme temperature, internal mechanism failure, and errors that are located found within the tape's file span.
With more organizations using tape as a storage media, damages done by water, absence of oxide, folds in the tape material, sliced edges, bad oxide and even frictional damage tape data can be recovered from tapes. There are generally two types of tape data recovery. These are known as physical recovery and logical recovery.
What is physical recovery for a tape data?
When there is a physical damage on the tape, a physical tape recovery is applicable. Physical damage such as cartridge crack, tape damage, failure in the internal mechanism of the tape and etc may prevents the data from being read efficiently.
Another reason for physical recovery can be due to the deterioration of magnetic coatings on the actual tape surface, broken or cracked wheels, twisted or folded tape, creased tape edges, broken tape, stretched tape, and etc.
There are lots of companies or stores promise a high recovery rate from using physical recovery methods. They claimed that they have over 98 percent success rate of their recovery techniques.
You may quickly need to bring your storage device to those highly trained recovery experts for recovery procedures, once you felt that you have damaged your tape storage device if it has been dropped in the mud, water or fall from high levels.
What is logical recovery?
Logical tape data recovery is more complicated than physical recovery, and is also more expensive than the normal recovery techniques.
When the data was successfully written onto the tape, but for some unknown reasons, it cannot be read or written, or simply there is no visible form of damage to the tape on the body itself.
In order for the technician to execute the recovery procedures properly, he has to use multiple versions of the tape recovery software and take many "passes" at the tape using it.
Using the recovery methods mentioned above, you can easily pieced back lost tape data. But the success rate of logical tape data recovery is much lower than the physical tape data recovery.
