1.Why USB drives can't be detected after plugging into computers?+
If the USB drive cannot be detected, here are some possible causes and solutions:
1. USB port issues: Try using a different USB ports on the computer or unplug and replug the drive a few times to see if it works.
2. Driver issues: Open Device Manager to check for any error symbols (⚠️). Try reinstalling the USB driver if needed.
3. USB drive malfunction: If the drive cannot be read on multiple devices, it may be damaged.
⚠️ If the above steps do not resolve the issue, please contact our customer support. We’ll assist you with further diagnosis and solutions!
2.Why is the actual storage capacity of USB drive slightly less than the capacity written on the product specification?+
The reason why the storage capacity displayed on a computer is always less than the actual capacity is due tobelow :
1. The difference in calculation methods. Computers use a binary system for storage calculation, where 1GB is equal to 1024 × 1024 × 1024 = 1,073,741,824 bytes (since 1024 is 2 to the power of 10).
2. USB drives are formatted by default setting such asFAT32, exFAT, NTFS which might reserves some space.
3. Additionally, it reserves some space of the total capacity for cache record, error correction etc.
💡 This is a normal condition and does not impact the functionality of the USB drive.
3.Why I am unable to save files larger than 4GB to USB drives?+
Our USB drives are pre-formatted in FAT32, which has a maximum file size limit of 4GB per file.
To store files larger than 4GB, you can reformat the USB drive to exFAT (compatible with both Windows & Mac) or NTFS (writeable on Windows only).
How to Format (exFAT is recommended):
Windows: Right-click the USB drive → Format → Select exFAT → Click Start.
Mac: Open Disk Utility → Select the USB drive → Click Erase → Choose exFAT → Click Erase.
4.USB 2.0 vs. USB 3.0 – Which one should I choose?+
Consider USB 2.0 if you need:
1. Mainly store documents, photos, or basic media files with no high speed requirements
2. Prefer a more cost-effective option for general backups or everyday file transfers
Consider USB 3.0 if you need:
1. Work with large files such as 4K videos, games, or project files
2. Need faster data transfer speeds
Note: USB 3.0 is backward compatible with USB 2.0 ports, but full speed is only achieved with a USB 3.0 or higher port
📌 Quick Recommendation:
Occasional use / small file transfers 👉 USB 2.0 is sufficient
Fast transfers / large data migration 👉 USB 3.0 is the better choice
5.Why I can't access the USB drive and get "Format Disk" error message?+
Possible Cause:
The file system may be corrupted, preventing the computer from reading the data.
Solutions:
If the USB contains important data, try recovering it using our recommended tool:
Recuva (File Recovery Software)

If there is no important data, you can use Disk Management to format the drive and create a new partition.
6.What should I do if I see a message saying “The file or directory is corrupted and unreadable” when accessing the USB drive?+
1. This issue may occur if the USB drive was improperly removed while saving data, causing damage to the internal file system.
2. To reduce the risk of data corruption, always perfor“Safely Remove Hardware" before unplugging the USB drive.
3. We recommend backing up your data first, then reformatting the USB drive.
If the issue causes, please contact our customer service team for further assistance and support.
7.What should I do if the computer shows “The device cannot be stopped” when trying to remove the USB drive?+
Try removing the USB drive in Safe Mode using these steps:
Start → Settings → Control Panel → System → Hardware → Device Manager →
Universal Serial Bus Controllers → USB Mass Storage Device
→ Right-click the device → Select Uninstall → Click OK.
Wait a moment and then safely remove the USB drive.
8.How can I ensure that data on my USB drive is not lost or damaged?+
USB drives are not designed for long-term storage. To keep your data safe, please follow these recommendations:
1. Back up regularly: USB drives have a limited lifespan. We suggest backing up important files to the cloud or an external hard drive.
2. Remove the drive properly:
Windows: Click the USB icon in the bottom-right corner → Choose Safely Remove Hardware → Remove the drive after confirmation.
Mac: Drag the USB icon to the Trash, or click the Eject button before unplugging.
3. Avoid extreme environments: High temperatures and humidity can shorten the lifespan of the USB drive. Store it in a cool, dry place.
4. Protect against viruses: USB drives are vulnerable to malware. Use antivirus software regularly and avoid connecting the drive to unprotected computers.
9.The OTG USB can't be recognized on phone device.+
Here are possible causes and solutions:
OTG function not enabled on the phone: Some phones require manually enabling OTG. You can turn it on via Settings → More Connections on the phone.
Phone system or app issues: Restart the phone, or use the built-in Files app or download a File Manager app to check if the OTG USB drive is detected.
Unsupported USB drive format: Some Android devices do not support exFAT or NTFS formats. Try formatting the drive to FAT32 on a computer (⚠️Formatting will erase all data).
10.Can OTG USB drives be used with all mobile devices?+
Compatibility Requirements:
1. Android phones/tablets: Must support OTG (On-The-Go) functionality. Most newer Android devices are OTG-compatible.
2. Windows/Mac computers: Can be used directly without additional setup.
3. iPhone/iPad (Lightning port): Requires a Lightning-compatible USB drive designed specifically for iOS devices.
💡 Tip: Before purchasing, check whether your device supports OTG. You can test this using an OTG checker app.
