  • Updated

A "file open/read/write" error message means that Qubii is detecting issues related to files stored in the microSD card. If you have received this error, recommend trying the following troubleshooting tips below:

  • Solution #1: Find the problematic files in your camera roll and delete them.
  • Solution #2: Reformat microSD card and restart backup.*
  • Solution #3: Insert a different microSD card and reinitiate backup

 

Solution #1: Find the problematic files in your camera roll and delete them

This error may be caused by one or a few corrupt files in your camera roll. In order to reset this error message, please try the troubleshooting steps below:

  1. Open the Qubii app and go to: Settings > Backup Details > find the latest backup date
  2. Go to your iPhone camera roll > find the latest backup date > delete 5 photos
  3. After you have completed the steps above, reinitiate the backup. 

Corrupt or damaged files can lead to error messages. Deleting or removing these files should resolve this issue and clear the error message. If you have deleted the files and the error message reappears or you could not find the files, please try solution #2. 

 

Solution #2: Reformat microSD card and restart backup.*

If you still receive the error message on your Qubii app, you may need to reformat your microSD card before trying to back up again.

 

*Please Note: Reformatting will delete everything that is currently stored in your microSD card. Ensure that you have already backed up any previously stored data from your microSD card to your computer before attempting to reformat. 

 

STEP 1: Reformat your microSD card.

STEP 2: Delete all backup records from the Qubii app.

STEP 3: Restart your iPhone and try backing up again from the beginning.

 

Reformatting the microSD card will verify that there is no corrupt data on the card that could have caused this error.

 

Formatting Methods for MicroSD Card:

Ｗindows:

  1. Connect Qubii to your Windows PC.
  2. Right click on the Qubii folder once it appears or find the Qubii folder in the File Explorer under "This PC".
  3. Select "Format"
  4. A new window will appear where you can choose the file system. Select exFAT.
  5. Done!

Mac:

  1. Plug Qubii into your Mac.
  2. Launch Disk Utility, located in Applications > Utilities.
  3. Locate the drive named "Qubii" from the left-hand side of Disk Utility and click on it.
  4. Click on the “Erase” tab across the top.
  5. Done!

*MAKTAR REMINDER: Please remember that formatting a microSD card will permanently delete all the data stored on the card. If there is any previously stored data on the microSD card, please backup your data to a computer before formatting.

 

After reformatting you should delete previous backup records to reset the Qubii app in order to start completely back up all files again.

 

How do I delete backup records in the Qubii app?

In the Qubii app > tap the top-right "settings" icon > Backup Details > Reset backup records

 

Solution #3: Insert a different microSD card and reinitiate backup

If after attempting both of the troubleshooting options above you are still receiving this error message, it could mean that:

  • Your microSD card may be damaged
  • Your microSD card could be a fake or counterfeit
We strongly suggest that you switch your microSD card and attempt to back up again or purchase a new microSD card from a trusted brand and seller.
 
*MAKTAR Reminder: These error messages commonly appear if the microSD card inserted into the Qubii is a damaged, poor quality or counterfeit. Although it may not be immediately apparent when the backup process begins, you may receive errors as more data is stored onto the microSD card. We strongly recommend purchasing a microSD card from a trusted seller. Watch out for and avoid fake or counterfeit microSD cards.
