Summary: RAW SD cards can become inaccessible, putting your data at risk. If you are looking for a secure solution to recover deleted RAW files from SD card, read this post.
A RAW SD card indicates that its file system is damaged or has corrupted. Since a file system is necessary for operating systems to access data stored on a drive, you cannot open a RAW SD card or any other storage drive.
What is a file system in an SD card? A file system organizes the drive’s data in tabular form so the operating system can steer to this data. SD cards are formatted to FAT 32, exFAT, NTFS, or other file systems. If the file system gets corrupted, your SD card becomes raw. Besides, a brand new SD card is also RAW until it is formatted to a specific file system for usage.
Further, a RAW SD card can throw different error messages while trying to open it. These error messages are signs of RAW SD card, hinting that your data is at risk. Here are some common error messages that a RAW SD card would display:
‘SD card is blank or has unsupported file system’
‘SD card is not formatted. Do you want to format it now?’
‘Windows cannot access the disk’
‘The type of the file system is raw. CHKDSK is not available for RAW drives.’
‘0 byte error.’
There can be various reasons why SD cards become raw. A malicious software, virus attack, sudden power cut or disconnect while transferring files from SD card to computer, etc. The file system of an old or unusable SD card over a long period can also get corrupt, making its files RAW.
A simple answer is ‘yes’. You can recover RAW data from SD card. Your data on RAW SD card is still present but uncategorized. Therefore, unreadable by the operating system. However, no manual hit and trial method will work. You require a professional SD card recovery software to recover RAW SD card data.
Meanwhile, solutions like formatting can only make your RAW memory card reusable but cannot get back the lost or deleted data on it. Further, it will permanently delete your current data on SD card.
