Solid State Drive Data Recovery
Solid State Drives are not immune from data loss. I recover cases such as human error, hardware failures, computer viruses, malware, physical damage, and software corruption just as as often as traditional hard drives.
Solid State Drive Data Recovery is becoming more common as drives are in more computers. SSD’s are fast and the best for storage but there is nothing magical about these devices. They do fail and components can wear out and fail from use. You should have a backup strategy. Unlike the hard drives, SSD’s do not give any signs of problems like slow read writes or clicking, when an SSD fails, it’s bad news.
What Causes SSD Data Loss?
Solid state drives store data in flash memory chips, and do not have moving parts like traditional hard drives. Common failures that occur with SSD or M.2 NVMe drives are:
- Heat and overheating
- Software corruption
- Electronic or Controller component failure
- Degradation of Flash Memory (Flash cells) from reading and writing
- Power surges or power loss
- Damage to circuit boards or SATA/M.2 connectors
- Data corruption after firmware updates
Professional data recovery services are now available.
Why is this more difficulty of a recovery?
Unlike the mechanical hard disk drives SSD’s and Flash Memory have diverse challenges for data recovery. The SSD’s have complex data structures that vary from individual brands to the specialized controller chips and other SSD specific parameters. Here some of the challenge for SSD recovery:
- Address line complexity
- Density of Memory chip
- Error correction code variables
- Encryption and Encoding variations
SSD’s have TRIM. The TRIM command organizes data on an SSD and improves its performance. TRIM allows an operating system to inform a solid-state drive (SSD) which blocks of data are no longer considered in use and can be wiped internally However, due to the nature of TRIM, data recovery efforts are less likely to be successful, and some times even impossible.
Interface Types of Solid State Drives
- SATA 2.5-inch Serial ATA
- M.2 SSDs
Many SSDs are encrypted by default, ensuring data security, but also make data recovery more complex.
