Nowadays, there is too much data recovery software available in market. Thus, for most users, as long as encountering data loss, they will select to apply data recovery software. Yet, in the 5 cases listed in this article, the software will fail definitely.
It is always advisable to back up your data on a regular basis. Only with backups, you can restore corrupt or lost data, such as damaged Outlook file, like a breeze. However, if you have no effective backups, you will need to attempt data recovery when encountering data loss. Generally, for a majority of users, they will invest in data recovery software to have a try. Nevertheless, no software is versatile. It still can fail in the following 5 situations.
1. Data Overwrite
When realizing data loss, such as accidentally deleting any files, you have to stop all operations at once. Otherwise, new data may be written to the location where the lost data was stored. This is so-called data overwrite. In addition, you should never recover data directly to the same drive in that the recovered data can cover the lost data, too. Later, if you find recovered data still inaccessible, you’ll regret it absolutely.
2. Full Format
At times, you may receive any error messages suggesting you to format the drive. Under this circumstance, you ought to consider whether to follow the advice with care in that formatting will delete all data. Of course, if you select “Quick Format”, software still can recover data. Yet, if you select “Full Format”, you’ll kiss your data goodbye forever. Full format will erase data completely.
3. Physical Damage
Aside from logical factors, data can be lost due to physical damage. For example, in a hard drive, if a sector is damaged, namely bad sector, the data on this sector will be corrupted. In this scenario, any data recovery software will not work since software is unable to deal with physical issues. Running such software will only result in further damage to your drive.
4. Run CHKDSK
As we all know, Windows provides a built-in disk scan and fix tool – CHKDSK. It’s able to detect bad sectors and mark them unavailable. Although it is really potent in disk repair, you shouldn’t run it after data loss due to bad sector. When a file is stored in a sector which is marked as bad by CHKDSK, the file will be remapped to a spare sector. Yet, there may be accidentally deleted file on the spare sector. In this case, the file will be erased thoroughly. Software will not help you, either.
5. Data Erase
Last but not least, if you suffer data loss due to that you run data erasure software, it is necessary to run data recovery software. Data erasure will wipe all the data on the drive completely without any bits existing. Hence, data recovery software will definitely fail.
