SSD Data Recovery

SDD drive internal architecture
SDD drive internal architecture

Solid State Drives (SSD) are being popular due to robust performance and its reliable usage. But the drive also prone to errors due to Electrical shock, over voltage, electronic component wear and tear, CRC errors or bad sector formation due to diode electron read and write do fail by time. The normal hard drive fail due to age, usage and mechanical wear and tear, the brand new normal hard drive would not fail so easily as the old hard drives with slow performance and symptoms of failure, SMART performance will be monitored during the BIOS for normally laptop and desktop to check the regular health condition. But SSD fails un-noticeably without providing any prior symptoms nor any failure notice, One day it works and an another the drive is dead and completely non readable and does not detect in any of the machine, the SSD does not provide SMART parameters for the drive, hence it is difficult to notice the failing SSD drives.

SSD Basically consists of 4 Main chip-sets or components

  1. Micro Controller,
  2. Flash or Storage
  3. Interface (like SATA, mSATA and Strip others)
  4. Flash Cache in modern SSD to cache information on fly.

The data crash in the SSD are classified with following types

  • Electronic Shock Damage
  • Electronic component wear and tear.
  • CRC Errors or Bad sectors in SSD due to flash degradation.
  • Controller Failure.
  • Connector damages due to wear and tear.
  • Electronic circuitry damages due to water or fire incident.
  • RAID Failure in the Flash devices.
  • Mechanical Shock due to fall or sudden hitting on any hard surface.

The Laptop manufactures are using the modern SSD as internal drives replacing the old mechanical hard drives, due to light weight and less power consumption than the older drives, the laptop like Macbook air, macbook pro are used with modern SSD with mini 24 pin and 18 pin connectors, the lenovo, ibm and hp laptop uses micro pinned SSD with different ports for new laptops.

The recovery is complicated based on the capacity of the drive and controller used in the same and recovery methods applicable via NAND recovery mode. The encryption in the SSD like bitlocker, truecrypt, mcafee saeboot and symantic encryptions are much more complicated than the normal SSD recovery, We are equipped with NAND recovery from flash drives and SSD drive recovery methods which can recover even from damaged SSD cards which are not in detection, direct recovery from the memory / flash chips inside the SSD Unit, the memory will be decrypted according to the controller information assigned with each manufacturers.
