Logical Failures & Bad Sectors
Logical failure means there is a corruption or failure within the software that is preventing access to your data. So although there is no physical damage to the internal components themselves, there is logical damage to the file system that prevents it from being read or written to. This can happen for a variety of reasons, such as malware or a virus, when hard drive recovery
may be necessary.
In order to retrieve these files, an individual engineer is assigned to your case where, after having run thorough diagnostics, the appropriate steps are taken for successful recovery.
