How to Recover Data from Solid State Drives (SSDs)

Lost your valuable data from solid state drive? Do not worry! The blog presents useful tips and ways through which you can recover the lost data from SSD Drive. Read on, to know how.

Solid state drive (SSD) is a non-volatile data storage device that uses an assembly of integrated circuits (ICs) as memory. Due to low random access and read latency time, the storage device is used in modern laptops, desktops, servers, and other applications that need real-time sending and receiving of information. Some benefits of SSD are listed below:

ADVANTAGES OF SSD

  1. Non-volatile
  2. Fast
  3. Silent
  4. Consumes quite less power
  5. Does not heat up
  6. Light-weight
  7. No moving parts
  8. Resistant to vibration, shock, movement, orientation

Besides the benefits, SSD also has some flaws as mentioned below:

DISADVANTAGES OF SSD

  1. High in price
  2. Amplified write operation
  3. Block erasure rather than sector or cell erasure
  4. The memory cell has finite erase cycle
  5. Erase block wear out due to constant rewrites

Although SSD is non-mechanical and far more superior to HDD, the former can fail without showing any failure symptoms and can lose data. Few common reasons for SSD failure are mentioned here:

SSD Data Recovery

TOP REASONS FOR SSD FAILURE:

Logical Damage

  • A computer virus can make SSD data inaccessible
  • File system corruption
  • Accidental deletion of files or folders
  • Formatting of solid state drive
  • Corruption in firmware
  • Power outage or low power can result in incomplete write
  • Charge leakage due to one or more years of inactivity
  • TRIM operation can erase block(s) to carry out garbage collection

Physical Damage

  • Inoperable NAND flash memory cells
  • Damage to its storage chips and internal circuitry
  • Damage to capacitor or battery
  • Failure of control chip
  • Spilling of water or any other liquid
  • Shorting of SSD
  • Damage due to the power surge
  • Exposure to extreme heat
  • This Logical or physical damage to SSD results in data loss.

SSD VS HDD
Contrary to HDDs where data can be overwritten on platter easily, SSD’s flash memory cells cannot be directly overwritten, but can be rewritten after the block containing the data is erased. Overwrite operation in SSD requires read, delete, modify, and rewrite.

When a file is deleted from SSD, it is marked as unused and left for the garbage collection. SSD with enabled TRIM command immediately and efficiently handles garbage collection to speed up write operation. The TRIM command though useful but leave no opportunity for data recovery. On the other hand, when a file is deleted from HDD, the pointer pointing to the file is updated instead of deleting the actual sector(s) containing the file, this leaves a chance for data recovery unless the data is not overwritten.

If you have lost data from SSD, don’t get disheartened. Equip yourself with the following tips and methods to mitigate data loss and recover data.

SSD DATA LOSS PREVENTION TIPS

  1. Protect your SSD from low power situation as well as power surges
  2. Update the firmware of the SSD from the manufacturer’s website frequently
  3. Refrain from reaching the peak of the SSD drive storage capacity
  4. Scan and remove malware from SSD on a regular basis
  5. Monitor your SSD usage and estimate its probable lifespan
  6. Stop using the SSD after the data loss until data recovery is made
  7. Consult a professional data recovery company to avoid data loss risk
  8. Backup data from the SSD to a PC or an external backup drive regularly
