The evolution of technology has transformed not only computers but also their storage solutions. While many laptops still rely on traditional 2.5-inch hard drives, modern devices increasingly feature SSHDs and SSDs. In particular, M.2 solid-state drives have gained popularity in ultra-thin models due to their compact design and superior performance.
Another key feature of contemporary laptops is self-encrypting drives (SEDs), which automatically encrypt data on the system drive, enhancing security for users.
Causes of Data Loss in Laptops
Data loss in laptops can stem from various issues, such as file system corruption or hardware failure. Accidental drops, impacts, or liquid exposure can compromise the hard drive’s functionality, leading to malfunction or complete failure. At PITS Global Data Recovery Services, we specialize in repairing and recovering data from laptops experiencing these challenges.
Case Study: Microsoft Surface Pro 5
Recently, our data recovery team was approached for an emergency recovery involving a Microsoft Surface Pro 5. The client accidentally spilled water on the laptop while working on a research paper, prompting him to seek our expertise after researching recovery options.
Initial Assessment
Upon receiving the device, our technicians conducted an immediate diagnostic assessment. The inspection revealed that moisture had caused a short circuit in the SSD controller. Fortunately, the client had promptly turned off the laptop and unplugged it, which helped limit further damage.
Recovery Steps
The recovery process involved two critical steps:
- Reading the NAND Chip Dump: We securely extracted the data from the NAND chips.
- Decrypting the Self-Encryption: We addressed the challenges posed by the drive’s self-encryption feature.
SSD NAND Flash Memory Recovery
NAND chips, which comprise millions of cells made from modified floating gate transistors, are essential for data storage in SSDs. These chips use high voltage to manage data writing and erasing.
Our data recovery experts transferred the NAND chips to extract all available data. The SSD’s microcontroller featured PRD level 1 protection, which safeguards the firmware stored in the internal flash memory from unauthorized access.
The debug interface remained active, but flash access was restricted once it was connected. Consequently, our engineer had to employ specialized techniques to decrypt the self-encrypted files on the SSD.
Decryption of the Microsoft Surface Pro 5 SSD
Self-encrypting drives utilize hardware-based encryption through an embedded AES cryptographic chip. This process encrypts the entire disk before writing data and decrypts it upon retrieval.
Encryption transforms data into complex blocks, making it difficult to interpret. Our data recovery expert utilized customized decryption scripts to restore the damaged SSD’s file system. Once decryption was successful, all recovered files were transferred to a new hard drive and sent back to the client after his approval.
Commitment to Quality and Speed
At PITS Global Data Recovery Services, we continuously strive to enhance the quality and efficiency of our recovery processes. With readily available spare parts and a team of dedicated professionals, we are committed to providing reliable data recovery solutions within the required timeframe.
If you experience data loss on your device, trust our expert team to deliver prompt and effective recovery services.
