A SanDisk 128 GB Micro SD card is experiencing an 'Input/Output Error' when trying to copy files from it, specifically resulting in the error 'Error splicing file: Input/output error'. This issue affects users who have tried mounting the card on multiple computers and using different copying methods.

This problem can be frustrating for those trying to recover data from the corrupted Micro SD card. In this guide, we will explore possible causes of the error and provide steps to recover as much data as possible.

🔍 Why This Happens

  • The primary cause of the 'Input/Output Error' on the Micro SD card is likely due to corruption or damage to the file system. This can occur when the card was used in an Android phone, leading to inconsistent access patterns and potential errors. Additionally, the card's age and usage history may also contribute to the issue.
  • Another possible cause of the error could be a firmware issue with the Micro SD card reader or the computer's operating system. In some cases, outdated drivers or corrupted system files can lead to I/O errors when interacting with external storage devices.
