What Causes ASUS ROG Ally Not Recognizing SD Card?

Some people encounter the “Asus ROG Ally not recognizing SD card” issue when they are trying to access an SD card on the ROG Ally.

After investigating extensive user reports and posts, I find that the primary reasons for the “Asus ROG Ally not recognizing SD card” issue are as follows:

  • Excessive temperature: Heat exhaust is placed below the SD card slot. So, under certain thermal stress conditions, the SD card reader of ROG Ally will fail to detect the SD card.
  • Faulty SD card: The SD card you are trying to use in ROG Ally has already been corrupted by abnormal insertion and removal, sudden power outage, insufficient USB power supply, and virus.
  • Dirty or damaged SD card slot: If the position of the top pins and the bottom pins inside of the SD card slot has been disrupted, it may cause false connections. Meanwhile, the dirty things on the bottom pins can also affect the data reading on the SD card.
  • Outdated or corrupted driver: If you haven’t updated your driver for a long time, the drivers may be outdated. Sometimes, the drivers may be corrupted by other programs or apps.
  • Insufficient power supply to the card reader: If your ROG Ally has in low battery, it may provide little power for the SD card reader and then it may cause the SD card unable to be recognized.
  • Outdated or malfunctioning ROG Ally firmware: If you haven’t updated your ROG Ally BIOS for a long time, the ROG Ally firmware may be outdated or cause temporary/random bugs.
  • Software issues and glitches: If there are conflicts between software or corrupt installation files on the ROG Ally, they can cause software issues and glitches.
  • Corrupted system settings: Bugs on Windows OS may cause corrupted system settings.
