If your RAID goes on strike and you have no backups, you will need to attempt data recovery. But once one fault is made in this process, you may loss all of your data. This article will tell you the 6 top mistakes you have to avoid in RAID recovery.
It is known that all the data storage media can get corrupted. Therefore, so as to keep your data well-protected, you’d better make a consistent data backup. It will come in handy if you suffer data corruption. For example, when Outlook crashes and your Outlook files get corrupted, if you have backups, you can easily recover damaged Outlook data from the backed up files. Apart from the precautions, you also ought to pay attention to your rescue measures.
When encountering damaged RAID data, you should keep cautious of each step if you intend to attempt data recovery on your own. Incorrect operations will lead to very terrible consequences. So here we will outline 6 most common faults you should avert, which will greatly increase the chance of successful data recovery.
1. Open a Hard Drive
Provided that you’ve detected or diagnosed that a hard drive is to blame in the RAID failure, you must be going to repair the hard drive. But please bear in mind that you should never open a drive casually, since that more damages may occur to the drive. Opening a hard drive requires specific conditions, including proper air pressure, tailored tools and a cleanroom, etc.
2. Re-create a Partition in the Same Place
When you delete a drive partition by accident, actually the data on this partition is not erased completely. So it is possible to recover the invisible data. But if you think that recreating a partition with the same parameters in the same place will get back the data, you’re wrong. This action can make your data inaccessible, and it will be much more difficult to recover them.
3. Format the Malfunctioning Drive
Sometimes, if a drive becomes unreadable, you may receive a suggestion from the operating system. It usually advises you to scan, check and format the hard drive that cannot function properly. If you follow the suggestion, you will say goodbye to your data forever, in that formatting will write new data on the drive. It refers to overwriting data. In this case, recovering data will become impossible.
4. Incorrect Operations in Drive Rebuild
When a RAID fails, rebuilding hard drive must be the first approach which will occur to most people’s minds. Of course, it indeed should be your first and best solution. But if you have no relevant specialized knowledge, never attempt it on your own. Rebuild is a process to create data redundancy and provide the array’s fault tolerance. One operational error will lead to the failure of the entire array.
5. Recover Data on the Original Drive
There is multiple data recovery software available in the market. Most of the time, they can really make effects. But before starting the recovery process, you should configure the software to recover data onto the other drive, not the original drive. Otherwise, your original data will be overwritten. Also, you should never install the software on the original drive.
6. Not Provide Crucial Info to Data Recovery Specialist
More often than not, you will consult data recovery expert for suggestions. They may require you to provide some crucial information about your cases. But most people cannot offer the actually needed and vitally important info. For instance, you’ve attempted to open a drive by yourself before, but you didn’t mention this when recurring to data recovery service. Without any doubts, the more precise the info you can provide, the higher the chances to recover your data will be.
