Although they are resilient and can handle environmental impacts, such as shock, temperature and physical vibration, SSD data is still susceptible to electrical damage, firmware corruption and controller failure. Three common types of flash/SSD failures are user error and environmental influences, electronics component failure, and system area corruption.
Some of the challenges specific to data recovery with SSDs include: several manufacturers in the SSD space, lack of standards in NAND manufacturing, proprietary chip pin outs, proprietary wear levelling algorithms, proprietary encryption, use of glue and other epoxy-like substances on the NAND chips and microscopic traces, along with many others.
Various operating system functions like TRIM and software components like background data collection (BGC) can be the most accounted reasons for the extended software complexity of retrieving data on SSD.
A file system defines the internal data organisation format on an SSD. File system also controls the access to both the metadata and contents of a file that exists in SSD as an entity. Data loss in SSD drives can happen due to the following reasons.
We use advanced SSD data recovery tools that employs a search algorithm to look out for the previous existing file systems and consequentially determines the physical address of previously existing content and the metadata. Hence it recovers the data by establishing a new file system for the orphaned data which helps in reconstruction of the file system.
