Data is recoverable from an ADATA SD card following accidental deletion, quick formatting, or RAW filesystem errors, provided the physical storage blocks have not been overwritten by new data or subjected to a full format.
● Choose **Wondershare Recoverit** for a user-friendly GUI capable of extracting and stitching together fragmented high-definition videos, or opt for **TestDisk** if you are an advanced user needing a command-line utility to rebuild lost partition headers.
● Halt all use of the ADATA card immediately upon noticing data loss to prevent overwriting the invisible files, and strictly avoid running the Windows `chkdsk` utility, which can permanently destroy remaining raw file signatures during its repair attempts.
● If the card suddenly locks into a "Write Protected" or "Read-Only" state, its internal flash controller has detected that the NAND memory cells have reached their maximum write limits, meaning you must extract your existing files to a separate drive before the hardware fails completely.

Recovering deleted files from an ADATA memory card is a simple process. Whether you accidentally erased the files or formatted the card, we can assist you in retrieving your lost data.
To begin, gather a computer, a card reader, and an ADATA SD card. While not all types of data loss can be easily fixed, most cases involving an ADATA memory card can be resolved. Here's a step-by-step guide on how to perform an ADATA SD card recovery.
Can I Recover Data From an ADATA SD Card?
Yes. Sometimes when you delete files from a digital storage device, they don't disappear right away. They stay on the device, hidden from view until they are overwritten by new data. This is why it's possible to recover lost data from a memory card. However, to know if data is truly lost from an ADATA memory card, you need to thoroughly scan the card.
Let's look at some common reasons for data loss on an ADATA SD card and the potential solutions:
🔍 Technical Overview: ADATA Memory Card File Vulnerabilities
Data storage on ADATA SD cards relies on flash memory chips controlled by a specialized firmware chip. When files are lost, the success of the recovery depends entirely on whether the physical storage blocks have been completely wiped or simply unlinked in the file allocation tables (FAT32/exFAT):
| Data Loss Scenario | Underlying Flash System Behavior | Recovery Feasibility | Recommended Tool Path |
| Accidental Deletion | The file directory flags are wiped, but raw clusters holding data blocks remain completely untouched. | 98% Success Rate | Wondershare Recoverit (Instant extension filter scan) |
| Quick Drive Format | Clears the file allocation index table. The flash memory blocks are not overwritten with zeros. | 95% Success Rate | Wondershare Recoverit (Deep raw file signature carving) |
| RAW File System Error | The master boot record (MBR) or partition definitions are broken by a sudden write disconnect. | 90% Success Rate | TestDisk (Direct partition header restoration) |
| Full / Low-Level Format | Every storage cell on the card is overwritten with zeros. | Impossible | None (Data blocks are permanently wiped from the NAND chips) |
| Severe Physical Damage | The NAND flash chip is cracked, snapped, or has suffered severe high-voltage shorts. | Hardware Expert Needed | Physical chip-off recovery via a specialized cleanroom service |
| Causes | Description |
| 🗑 File Deletion | Accidentally deleting files is the most common reason for data loss; Fortunately, it's usually easy to fix. If you stop using the ADATA card and haven't overwritten the deleted files, you can use data recovery software to retrieve them. |
| 🔄 Formatting | When you format a card with Quick Format, it erases the file table. However, the files are still present on the card. A good data recovery software can scan the formatted SD card and restore the files. If you perform a Full Format on the SD card, the data becomes irretrievable. |
| 🔨 Physical Damage | Software solutions can only fix slightly physical damage. In severe cases, you should contact a specialized SD card data recovery service that can attempt to retrieve the data using specialized methods. |
Remember, the data may become permanently lost if you continue using the card. New files can overwrite the invisible deleted files, making data recovery impossible. Therefore, stop using the card once you become aware of data loss.

FAQs
-
Why does my ADATA SD card display an "I/O Device Error" when connected to my computer?
An Input/Output (I/O) device error typically means that your computer's operating system is unable to read the data sectors or flash controller on your ADATA card. This can be caused by dirty metal contacts on the card, a faulty USB cable, or a broken card reader slot. Before running any data recovery software, clean the gold contacts on your card using a lint-free cloth and try a different card reader or USB port. If the error persists across multiple computers, it usually indicates that the card's internal flash controller chip has suffered physical failure. -
Can I recover video files from an ADATA card that was formatted inside a DSLR camera?
Yes. When a DSLR or mirrorless camera formats an ADATA card, it typically performs a "Quick Format." This process clears the file indexing system but leaves the actual video frames stored on the storage blocks. However, because modern cameras write high-definition video in fragmented fragments across the card, standard file recovery tools may restore broken, unplayable video files. Wondershare Recoverit resolves this by using an advanced video recovery engine that automatically matches and stitches scattered video fragments back into a single, working file. -
How do I fix an ADATA MicroSD card that shows up as "Write Protected" or "Read-Only"?
When an ADATA memory card switches into an unchangeable read-only mode, it is usually because the card's built-in flash controller has detected that the NAND memory cells have reached their maximum write limit. The card locks itself to prevent data corruption. If you are using a full-sized SD card adapter, make sure the tiny mechanical lock switch on the left edge is pushed all the way up. If the card remains locked, you can still use **Wondershare Recoverit** to pull your existing files off the card and save them to a safe location before replacing the card. -
Is it safe to use Windows Chkdsk utility to repair a corrupted ADATA SD card?
No, using the `chkdsk` command on a corrupted or RAW memory card before recovering your files can be risky. While Chkdsk will try to fix the card's file allocation tables, it does so by forcibly cutting off or correcting any damaged indexing data that it cannot read. This process can overwrite or delete your remaining raw file signatures, making it much harder for recovery software to find them. Always use a secure tool like Wondershare Recoverit to scan and extract your files *before* attempting any system command-line repairs.
