I have a memory card which i received from an institute. Even though it is not read-only its files are, so I cannot delete or copy something to the memory card. I have tried diskpart clean and it returns the error "DiskPart has encountered an error: Data error (cyclic redundancy check)."

Cyclic redundancy error means a bad sector on the card.

The card has most probably gone bad, so ask for a replacement.

If any important data needs salvage, see the following article for free products:

  • In that case the card is dead. – harrymc Jul 28 '19 at 05:51
  • I am able to use the file that are on the SD card, what i can't do is delete them or copy new things – Rachit Jul 29 '19 at 18:12
  • This might be a simpler case, where you just don't have full permissions on these files. In this case the card is good. For gaining ownership and permissions see this answer that uses batch commands, but you may do the same from Explorer. – harrymc Jul 29 '19 at 20:07
  • It's not showing the security option when i click on properties, there's only General, Customize, and Sharing and when using takeown command it's displaying"File ownership cannot be applied on insecure file systems; there's no support for ACLs – Rachit Aug 02 '19 at 09:30
  • The card is then formatted as FAT32 or similar that has no permissions. The last possibilities are damage that affects these operations or a hardware lock that prevents any modification. For the last option, search for any switch on the card itself. If you can find nothing, I recommend giving up on the card. – harrymc Aug 02 '19 at 09:37
