What Does It Mean When an SD Card Is Corrupted?
SD card corruption usually refers to logical damage rather than physical failure. The data still exists, but the system cannot read it correctly.
Common symptoms include:
- “Você precisa formatar o disco antes de poder usá-lo.”
- SD card shows as RAW no Gerenciamento de disco.
- Files appear with strange names or cannot be opened.
- The card is detected but inaccessible.
In practical recovery scenarios, corruption often occurs due to improper ejection, power interruption, virus infection, or erros no sistema de arquivos. Understanding this distinction is important because corrupção lógica is often recoverable, while physical damage is not.
Can You Recover Files from a Corrupted SD Card?
Yes, in many cases you can recover files from corrupted SD card, provided the memory chip itself is not physically damaged.
A recuperação geralmente é possível quando:
- The SD card is detected by Windows.
- The card shows incorrect capacity or file system errors.
- Files disappeared suddenly after an error message.
Recovery becomes unlikely when:
- The card is not detected on any device.
- There is visible physical damage.
- The card overheats or disconnects randomly.
From a professional perspective, corrupção lógica still leaves data intact. The challenge is accessing it safely without triggering overwrites.
Important: Recover Files Before Repairing the SD Card
This step is where many users make critical mistakes. Repair tools like CHKDSK are designed to fix file systems, not protect data. In practice, CHKDSK may delete damaged file records to restore consistency.
That is why experienced technicians always follow this sequence:
1. Stop using the SD card immediately.
2. Recover important files first.
3. Repair or format the SD card only after recovery.
Following this order significantly improves the success rate when you recover files from corrupted SD card.
How to Recover Files from a Corrupted SD Card Using CMD
The method most commonly associated with CMD is the Comando CHKDSK. While popular, it is not always safe.
When CMD Works and When It Does Not
CMD-based recovery may work if:
- The file system has minor erros lógicos.
- The SD card still has a recognizable drive letter.
CMD should be avoided if:
- O card é exibido como RAW.
- Files are already missing.
- Data is critical and irreplaceable.
Step-by-Step: Using CHKDSK on a Corrupted SD Card
1. Insert the SD card into your computer.
2. Open Command Prompt as Administrator.
3. Type the command:
chkdsk X: /f /r
Replace X with the SD card drive letter.
4. Press Enter and wait for the process to finish.
Se CHKDSK succeeds, recovered files may appear in a FOUND folder. However, file names and structures are often lost. In many cases, users discover that CHKDSK removes corrupted entries instead of restoring them.
This is why CMD should be treated as a repair tool, not a primary data recovery solution.
