How to fix a RAW micro SD card and recover data from it?

Hi everyone, I have a corrupted micro SD card that shows RAW as its file system in Disk Management. I have tried using CHKDSK in cmd (admin mode) as follows: chkdsk G: /f /r. But I get the message that CHKDSK is not available for RAW drives. Therefore, does someone know how to solve this error and fix the micro SD card? More importantly, how do I retrieve my data if it can't be fixed? I would really appreciate your help.

If the CHKDSK command fails to repair your RAW micro SD card, then your best shot is to format it. Formatting an SD card would wipe off all files stored on it, so you can use data recovery software like iBoysoft Data Recovery for Windows to get your data off of it first.

You said that after you use chkdsk G: /f /r in cmd and receive an error message "CHDSK is not available for RAW drives", which indicates that your micro SD card is heavily corrupted. In this situation, you should perform the SD card RAW recovery in two steps. First, retrieve your data from the faulty SD card. Second, reformat the micro SD card.

Step1. Recover files from the RAW micro SD card

Since your SD card is RAW, all files stored on it remain inaccessible until the RAW status is removed. So you can't copy and paste your files to another storage device. But, a data recovery tool like iBoysoft Data Recovery for Windows can give you a hand.
