6. Manutenzione
To ensure the longevity and optimal performance of your GRAUGEAR G-MP01CR, follow these general maintenance guidelines:
- Mantenere l'unità libera da polvere e detriti. Utilizzare un panno morbido e asciutto per la pulizia.
- Evitare di esporre l'unità a liquidi o a umidità eccessiva.
- Non tentare di smontare l'unità, poiché ciò potrebbe invalidare la garanzia e causare danni.
7. Risoluzione Dei Problemi
If you encounter issues with your GRAUGEAR G-MP01CR, refer to the following troubleshooting tips:
- No Power/Device Not Detected:
- Ensure the 15-pin SATA power connector is securely attached to the unit and connected to your PSU. The card reader and some USB functions require this power.
- Verify that the 19-pin USB 3.0 and 20-pin USB 3.2 Key-A Type-E cables are correctly and firmly plugged into their respective headers on the motherboard. Incorrect orientation of the Type-E connector can prevent functionality.
- Check your motherboard's manual to confirm the presence and location of the required headers.
- Velocità di trasferimento dati lente:
- Ensure you are using the correct USB port for your device's capabilities. The 20Gbps USB-C port requires a USB 3.2 Gen 2x2 compatible device and motherboard header to achieve maximum speeds.
- Verify that your cables are rated for the desired speed (e.g., USB 3.2 Gen 2x2 cables for 20Gbps).
- Confirm that your motherboard drivers are up to date.
- Scheda SD/MicroSD non rilevata:
- Ensure the SD card is inserted correctly, with the label facing down.
- Check if the card is properly seated in the slot.
- Provare la scheda su un altro dispositivo per escludere un malfunzionamento.
- Unit Does Not Fit 3.5-inch Bay:
- Confirm that the bay is indeed a standard 3.5-inch bay. If you are attempting to install it in a 5.25-inch bay, an adapter bracket is required.
