What To Do When Data Is Lost
Accidental overwriting or deletion is a common cause of data loss. In this scenario, minimal use of the computer before attempted recovery ensures the odds of being able to retrieve data. If data is lost in this manner, be sure to get your storage media to a data recovery service promptly to improve the chances of recovery. If data is unreadable from an optical disk, don't attempt to "fix" it by cleaning the disk using a cloth or by applying any substances whether it's simply water or any other cleaning agents. Quite often, people tend to be too forceful when attempting to clean the disk which will damage the disk further and reduce the possibility of recovering any data from the device.
The same would apply to any other device that is failing to read. Simply store it away safely until a data recovery service attempts to retrieve the data from it. Attempting to read the data by plugging in the device repeatedly may lead to frustration and you may damage the device.
Once you have taken the above precautions to prevent further damage of the data, the next step would be to choose your data recovery company. The ideal place to look for data recovery services would be online. One simple search for Los Angeles data recovery services will reveal dozens of options. A great way to consider the quality of a service would be to look for customer reviews. Multiple positive reviews would indicate that the software used by the company is efficient. Next, take a look at the price; once you find a reputable service for a decent price, simply contact them and proceed from there.
