Troubleshooting

If you encounter issues with your SSK Portable SSD, try the following solutions:

ProblemPossible Solution
SSD not recognized by device.
  • Ensure the cable is securely connected to both the SSD and your device.
  • Try a different USB port on your device.
  • Test the SSD with another compatible device to rule out device-specific issues.
  • Check your device's disk management or file explorer to see if the drive appears, even if not automatically mounted. You may need to initialize or format the drive if it's new or has been used on a different operating system.
  • Ensure your device's operating system is up to date.
Slow data transfer speeds.
  • Ensure your device's USB port supports USB 3.2 Gen2 (or at least USB 3.0). Connecting to a USB 2.0 port will result in significantly slower speeds.
  • Verify the cable used is the original SSK 2-in-1 cable or another high-quality USB 3.2 Gen2 compatible cable.
  • Close other applications that might be using system resources or performing background data transfers.
  • Ensure the SSD is not nearly full, as performance can degrade when storage is almost exhausted.
LED indicator not blinking.
  • The LED blinks during data transmission. If no data is being transferred, it may be solid or off.
  • If the SSD is connected and not recognized, refer to "SSD not recognized by device" above.
Data corruption or errors.
  • Always safely eject the SSD before disconnecting.
  • Run a disk check utility on your operating system to scan and repair any errors on the drive.
  • Ensure your device is free from malware or viruses.
