Hello
It seems like Windows might be hibernating or fast booting, which can cause issues when accessing shared drives from Ubuntu. When Windows hibernates or fast boots, it leaves the shared drives in an inconsistent state, preventing Ubuntu from mounting them properly.
To resolve this issue, you can try the following steps:
Disable Fast Startup in Windows: Go to Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable. Then, uncheck "Turn on fast startup" under Shutdown settings.
Unmount the Drive in Windows: Boot into Windows and make sure to unmount the shared drives properly before shutting down or restarting the system. This will allow Ubuntu to access the drives without issues during the next boot.
Mount the Drive in Ubuntu: After disabling fast startup in Windows and ensuring the drives are properly unmounted, boot into Ubuntu, and try to mount the shared drives again.
