Precautions:

  • If your data is not important & your memory card is under warranty, best way is to replace the card from the manufacturer service center.
  • If your data is not important & your memory card is out of warranty, don’t waste time on internet to find any solutions to repair it if the above instructions didn’t work for you. (nothing can be done)

Data Recovery:

  • If your data is very important & you are facing the same 31 Mb Raw Partition issue or card may be heating as well, please follow these steps:-
    1. Please Don’t plug-in the memory card again & again to PC or Laptop, it can cause much more damage to the internal components & data recovery chances can be reduced.
    2. Don’t download free data recovery or paid data recovery software and try to recover data as it won’t help ( Special hardware tools required to retrieve data, no software can help )
    3. Data Recovery of memory card at this situation can cost you a lot in India (Minimum 20000/- INR)
    4. If you can afford that much amount, please only contact a Professional Data Recovery Service Provider which can deal with Physical Media Recovery of memory cards. ( Please don’t visit any computer repair shop, they can’t help you in this case )
    5. Even Experts in recovery of hard drive data may not be able to help you, as this case is beyond their limits, and it needs special tools & equipment for this case.
