Hi, I am helping a friend out with recovering data from an SD Card. They were moving things off their phone and they canceled the transfer just as it started and now nothing is reading the contents of the card. I have tried using linux to read the card and have also tried running chkdsk to no avail. What else can i do to attempt to repair this card? when you plug it in the card takes a good few minuets to appear in Windows but does not show any partitions. Disk Management also does not seem to load either when the card i in the computer. The card seems to read as RAW in CHKDSK.
You can try to fix the damaged SD card via formattting SD card. But what you need to pay attention is that formatting will delete all data on it. Thus, you can recover data from the RAW SD Card to another place using data recovery software, if you don’t want suffer from data loss.
“They were moving things off their phone and they canceled the transfer…” - that is the reason why SD card can become a RAW)))
  Well, don’t worry, you can fix it with diskpart! That is in build windows tool. It is pretty much better than simple formatting!
You can use the algorithm from here SD card RAW format recovery  (use the code from black&white picture).
  But remember: that will remove all your files, so save them first. You can use their software - Uneraser or any other that you like, but restore files first - there will be a small chance to restore them after diskpart.
Hello, may be you can try updating the USB device driver.
Enter into Device Manager by typing” devmgmt.msc” in the Win+R window, and then choose “Update Driver Software”.
And I find a ste that contains four ways to recover SD card corrupted and RAW issue, hope it can help you.
If your friend’s SD card is showing as RAW in CHKDSK and isn’t recognized properly by Windows, using a specialized data recovery tool like Disk Drill could be helpful. Here’s a simplified approach:
- Download Sd Card Recovery Software: Get it from its official website, ensuring compatibility with your OS.
- Connect the SD Card: Insert the card into your computer via card reader.
- Run Software: Open the program and select the SD card for scanning.
- Perform an SD Card Scan: Choose a deep scan to thoroughly search for recoverable data.
- Preview and Recover: After the scan, preview the files and select those you wish to recover.
Remember, the success of data recovery can vary depending on the card’s condition and the type of damage.
The last option would be to format the card. You see, chkdsk can fix the filesystem errors and repair the card, but if you are unable to do so, then format it from the cmd only. Use this resource to format SD card and recover lost data from it.
OFC, when a data transfer is abruptly stopped, it can lead to corruption in the file system. This is just logical damage; you only need to format the problematic SD card. However, the downside of this method is the data on the card will be erased completely. Wanna repair a RAW SD card? Well, I recommend hiring a professional to handle the job. Without specialized tools and techniques, it is almost impossible to fix a severely damaged SD card at home.
Don’t waste your money on commercial data recovery software. For RAW drive recovery, data recovery services are more reliable.
