Storage media is very risky data damage. In Storage Media there are several types that can cause data damage. If data damage has occurred then the steps that must be done is to restore it so that data can be accessed again. Data corruption can occur due to several factors as mentioned earlier because of the occurrence of damage to operations that cause data damage.
Data Storage Media is a data storage device that serves as a tool / media for storing data and programs where data / stored programs can be read and reopened for re-processing on a computer or laptop.
Storage Media The computer has a variety of media, but in computers computer storage tool only has 3 categories of data storage media only as follows:
Types of Damage and Storage Media types
Some types of damage that can occur include:
1. Transaction failure
There are several types of errors that may cause a transaction to fail:
hardware jam (hang), causing the contents of the storage media temporarily lost.
3. Failure/disk damage
the presence/occurrence of bad sectors or disks jammed during the operation of I / O to disk.
There are several types of storage media (storage), which can be distinguished in terms of speed, capacity and also resistance to damage:
1. Temporary storage media (volatile storage)
The information contained in this storage medium exists only as long as the electrical current flows. If the electrical record is disconnected, then the information/data stored will be lost. However, the advantages of this storage media is located at a very high speed. Examples of storage media are RAM (Random Access Memory), Cache and register.
2. Permanent storage media (non-volatile storage)
The information that exists in this storage media still exists even though the electrical record does not flow again.
3. Stable storage media (stable storage)
The information contained in this storage media is never lost/damaged (physically by internal factors).
The recovery mechanism has two main parts:

Storage Media The computer has a variety of media, but in computers computer storage tool only has 3 categories of data storage media only as follows:
- Magnetic Storage Media (Magnetic Storage Media)
- Optical Storage Media (Optical Disk)
- Cloud Storage
Types of Damage and Storage Media types
Some types of damage that can occur include:
1. Transaction failure
There are several types of errors that may cause a transaction to fail:
- Logical error, where the program can not continue its normal execution because of certain internal conditions such as false/corrupt input, unavailable data, data values outside the limit of overflow domains, incorrect program logic.
- System error, where the program/system has entered an unexpected condition (such as deadlock), as a result of not executing the program/system normally.
hardware jam (hang), causing the contents of the storage media temporarily lost.
3. Failure/disk damage
the presence/occurrence of bad sectors or disks jammed during the operation of I / O to disk.

The recovery mechanism has two main parts:
- Actions taken during the normal course of transactions to ensure that adequate information is required for recovery mechanisms.
- Actions taken after the occurrence of system failure / failure performed to restore the contents of the database to a state that ensures database consistency, keatomikan, and transaction resilience.
