  • If your data is not important & your memory card is under warranty, best way is to replace the card from the manufacturer service center.

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.
