So I moved my onedrive to an SDHC card around 6 months ago because the hardrive space on my laptop is very small (only 32GB). This has been working perfectly fine for me.
The other day, my sister added her user account to my laptop and uploaded her onedrive to the same SD card. This card remains in the laptop.
Today, I turned on my laptop and a message came up saying:
"THe location where you were trying to create OneDrive folder belong to a drive with unsupported file system. To have OneDrive use a different location, click "Set up OneDrive" and point OneDrive to a NTFS drive. To use the existing location with OneDrive, you need to format it with NTFS then click "Set up OneDrive" to configure your account.
Why has this only appeared now? I don't know how to format the SD card with NTFS..
