I just bought a SanDisk sd card to put in my iScan portable scanner, when i tried to use it, the sd icon advised me it was full. I formatted the card even if it was brand new, so theorically empty.
Once done the format I put the card in the scanner again and still when I try to scan something the card icon says “full”. Is it a scanner issue or is there something you can advise me to do to solve this problem ? Thank you 
Hi @Regina
Have you opened a Support Case? If not opened, for more information, please contact the SD Technical Support team for best assistance and troubleshooting:

did you ever figure this out? having the same issue.
To resolve the issue, try reformatting the SD card on your computer using FAT32 or exFAT. Make sure the scanner is compatible with the card type (SDHC or SDXC). If the problem persists after these steps, the issue may be with the scanner itself.
Such issues could be caused due to virus intrusion, bad sectors, corrupt file systems, improper handling, manufacturing defects, or transfer interruptions. The easiest solution is to format the SD card. But there could be other methods as well to fix the issue.
I believe CHKDSK could be helpful and it could fix the issue. However, check this article to fix the SD card showing full issue.
